9b350f9ecc cmake: some formatting fixes
Do not include bootloader in flash target when secure boot is enabled.
Emit signing warning on all cases where signed apps are enabled (secure
boot and signed images)
Follow convention of capital letters for SECURE_BOOT_SIGNING_KEY
variable, since it is
relevant to other components, not just bootloader.
Pass signing key and verification key via config, not requiring
bootloader to know parent app dir.
Misc. variables name corrections

037c079e9a esp32: Refactor backtrace and add esp_backtrace_print()
This commit refactors backtracing within the panic handler so that a common
function esp_backtrace_get_next_frame() is used iteratively to traverse a
callstack.

A esp_backtrace_print() function has also be added that allows the printing
of a backtrace at runtime. The esp_backtrace_print() function allows unity to
print the backtrace of failed test cases and jump back to the main test menu
without the need reset the chip. esp_backtrace_print() can also be used as a
debugging function by users.

- esp_stack_ptr_is_sane() moved to soc_memory_layout.h
- removed uncessary includes of "esp_debug_helpers.h"

562af8f65e global: move the soc component out of the common list
This MR removes the common dependency from every IDF components to the SOC component.

Currently, in the ``idf_functions.cmake`` script, we include the header path of SOC component by default for all components.
But for better code organization (or maybe also benifits to the compiling speed), we may remove the dependency to SOC components for most components except the driver and kernel related components.

In CMAKE, we have two kinds of header visibilities (set by include path visibility):

(Assume component A --(depends on)--> B, B is the current component)

1. public (``COMPONENT_ADD_INCLUDEDIRS``): means this path is visible to other depending components (A) (visible to A and B)
2. private (``COMPONENT_PRIV_INCLUDEDIRS``): means this path is only visible to source files inside the component (visible to B only)

and we have two kinds of depending ways:

(Assume component A --(depends on)--> B --(depends on)--> C, B is the current component)

1. public (```COMPONENT_REQUIRES```): means B can access to public include path of C. All other components rely on you (A) will also be available for the public headers. (visible to A, B)
2. private (``COMPONENT_PRIV_REQUIRES``): means B can access to public include path of C, but don't propagate this relation to other components (A). (visible to B)

1. remove the common requirement in ``idf_functions.cmake``, this makes the SOC components invisible to all other components by default.
2. if a component (for example, DRIVER) really needs the dependency to SOC, add a private dependency to SOC for it.
3. some other components that don't really depends on the SOC may still meet some errors saying "can't find header soc/...", this is because it's depended component (DRIVER) incorrectly include the header of SOC in its public headers. Moving all this kind of #include into source files, or private headers
4. Fix the include requirements for some file which miss sufficient #include directives. (Previously they include some headers by the long long long header include link)

This is a breaking change. Previous code may depends on the long include chain.
You may need to include the following headers for some files after this commit:

- soc/soc.h
- soc/soc_memory_layout.h
- driver/gpio.h
- esp_sleep.h

The major broken include chain includes:

1. esp_system.h no longer includes esp_sleep.h. The latter includes driver/gpio.h and driver/touch_pad.h.
2. ets_sys.h no longer includes soc/soc.h
3. freertos/portmacro.h no longer includes soc/soc_memory_layout.h

some peripheral headers no longer includes their hw related headers, e.g. rom/gpio.h no longer includes soc/gpio_pins.h and soc/gpio_reg.h

cfba157fdd spi_slave: add valid check for DMA buffers
The DMA cannot receive data correctly when the buffer address is not
WORD aligned. Currently we only check whether the buffer is in the DRAM
region.

The DMA always write in WORDs, so the length arguments should also be
multiples of 32 bits.

A check is added to see whether the buffer is WORD aligned and has valid
length.

8bba348528 aes/sha/mpi: Bugfix a use of shared registers.
This commit resolves a blocking in esp_aes_block function.

Introduce:
The problem was in the fact that AES is switched off at the moment when he should give out the processed data. But because of the disabled, the operation can not be completed successfully, there is an infinite hang. The reason for this behavior is that the registers for controlling the inclusion of AES, SHA, MPI have shared registers and they were not protected from sharing.

Fix some related issue with shared using of AES SHA RSA accelerators.

4132834faa test: fix the unit test fail issue under single_core config
Introduced in 97e3542947.

The previous commit frees the IRAM part when single core, but doesn't
change the memory layout functions. The unit test mallocs IRAM memory
from the heap, accidently into the new-released region, which doesn't

a20d9287fe soc: use _EARLY versions of ESP_LOG
Some logging done in soc component may happen before logging via
stdout is possible. Use _EARLY version of log calls to make sure that
output is visible. The downside is that application does not have a
way to silence these logs. However since the soc component doesn’t
use any LOGV/LOGD/LOGI and only logs warnings and errors, this should
not impact the application.

22b840f3df bootloader: don’t reload RTC_FAST DRAM after deep sleep
When CONFIG_ESP32_RTCDATA_IN_FAST_MEM is enabled, RTC data is placed
into RTC_FAST memory region, viewed from the data bus. However the
bootloader was missing a check that this region should not be
overwritten after deep sleep, which caused .rtc.bss segment to loose
its contents after wakeup.

2e31cce390 soc/rtc: CPU frequency settings refactoring
Previous APIs used to set CPU frequency used CPU frequencies listed in
rtc_cpu_freq_t enumeration. This was problematic for two reasons.
First, supporting many possible frequency values obtained by dividing
XTAL frequency was hard, as every value would have to be listed in
the enumeration. Since different base XTAL frequencies are supported,
this further complicated things, since not all of these divided
frequencies would be valid for any given XTAL frequency. Second,
having to deal with enumeration values often involved switch
statements to convert between enumeration and MHz values, handle
PLL/XTAL frequencies separately, etc.

This change introduces rtc_cpu_freq_config_t structure, which contains
CPU frequency (in MHz) and information on how this frequency has to
be generated: clock source (XTAL/PLL), source frequency, clock
divider value. More fields can be added to this structure in the
future. This structure simplifies many parts of the code, since both
frequency value and frequency generation settings can be accessed in
any place in code without the need for conversions.

Additionally, this change adds setting of REF_TICK dividers to support
frequencies lower then XTAL with DFS.

If the RTC crystal is bad or has no matched capacitance, then you do not need to start such the crystal. It is necessary to determine this case, output an error (about impossibility to start from the oscillator) and start from the internal RC of the chain.

Reduced the default value of the number of bootstrap cycles. Because we can oscillating the oscillator which then stops. (in Kconfig). Changed from 100 to 5.

The number of calibration cycles has been increased. It is the main criterion for estimating the launch of an oscillator. A large increase leads to an increase in the load time, as well as the stability of recognition of this case. (in Kconfig).
Changed from 1024 to 3000.

1. External 32kHz crystal is started for too long or it may not start at all. It is often observed at the first start.
2. At the first start, it is possible that the crystal did not start. And the recorded period was recorded as 0. Which led to a division error by zero during the transition to the deep sleep mode (Maybe somewhere else).
3. Added a unit test to test a new method of oscillation an external crystal.
4. Added a new method of oscillating of an external crystal. The legs of the crystal are fed with a 32 kHz frequency.

The new method eliminates these errors.

Added unit test: `\esp-idf\components\soc\esp32\test\test_rtc_clk.c`: `make TEST_COMPONENTS=soc`
- 8 Test starting external RTC crystal. Will pass.

`Bootstrap cycles for external 32kHz crystal` - is specified in the file Kconfig by default 100.

QA tested a new method of oscillation the crystal on 25 boards. The supply of square waves on the crystal showed a 100% result in contrast to the previous method of launching the crystal. After the tests, the old method was deleted.

1618dbc9a5 soc/rtc: wait for frequency switch to complete
The fast path of CPU frequency switch function, used in DFS, was not
waiting for the frequency switch to complete when switching from XTAL
to PLL. This resulted in incorrect reads from peripherals on APB,
where two consecutive reads could return the same value. For example,
in esp_timer, read of FRC_COUNT_REG would return same value as the
preceding read of FRC_ALARM_REG, causing time to jump by the value of
FRC_ALARM_REG / apb_freq_mhz.

0c9e2c0fba esp_adc_cal/Remove lookup table
This commit removes the lookup table mode due to inferior performance when compared
to linear mode under attenuation 0, 1 and 2. However small portions of the lookup table
are kept for the higher voltages of atten 3 (above ADC reading 2880). That voltage range
in atten 3 has non linear characteristics making the LUT performan better than linear mode.

70ab924dbb Especially when internal memory fills up, some FreeRTOS structures (queues etc) get allocated in psram. These structures also contain a spinlock, which needs an atomic-compare-swap operation to work. The psram hardware, however, does not support this operation. As a workaround, this patch detects these spinlocks and will, instead of S32C1I, use equivalent C-code to simulate the behaviour, with an (internal) mux for atomicity. 2018-02-02 17:11:06 +08:00

eb5752c635 esp_restart: fix possible race while stalling other CPU, enable WDT early
Previously esp_restart would stall the other CPU before enabling RTC_WDT.
If the other CPU was executing an s32c1i instruction, the lock signal
from CPU to the arbiter would still be held after CPU was stalled. If
the CPU running esp_restart would then try to access the same locked
memory pool, it would be stuck, because lock signal would never be
released.

With this change, esp_restart resets the other CPU before stalling it.
Ideally, we would want to reset the CPU and keep it in reset, but the
hardware doesn't have such feature for PRO_CPU (it is possible to hold
APP_CPU in reset using DPORT register). Given that ROM code will not use
s32c1i in the first few hundred cycles, doing reset and then stall seems
to be safe.

In addition to than, RTC_WDT initialization is moved to the beginning of
the function, to prevent possible lock-up if CPU stalling still has any
issue.

f11ad0c904 soc/rtc: fix spurious warnings about XTAL frequency on startup
1. Make sure that 8MD256 clock used to estimate XTAL frequency is enabled
   before trying to use rtc_clk_cal_ratio.
   This fixes "Bogus XTAL frequency: 0 MHz" warnings after software reset.

2. Don't call rtc_clk_xtal_freq_estimate if XTAL frequency is already
   known. This reduces startup time after deep sleep or software reset.

3. Compare known XTAL frequency and estimated one before printing a
   warning. This fixes "Possibly invalid CONFIG_ESP32_XTAL_FREQ setting
   (40MHz). Detected 40 MHz." warnings.

6d4ed4ff6c soc/rtc: wait for SLOW_CLK cycle when switching CPU clock
Previous implementation waited for 20us after setting
RTC_CNTL_SOC_CLK_SEL_XTL register, using ets_delay_us, assuming that
the CPU was running at XTAL frequency. In reality, clock switch happened
on the next RTC_SLOW_CLK cycle, and CPU could be running at the previous
frequency (for example, 240 MHz) until then.
ets_delay_us would wait for 20 us * 40 cycles per us = 800 CPU cycles
(assuming 40 MHz XTAL; even less with a 26 MHz XTAL).
But if CPU was running at 240 MHz, 800 cycles would pass in just 3.3us,
while SLOW_CLK cycle could happen as much as 1/150kHz = 6.7us after
RTC_CNTL_SOC_CLK_SEL_XTL was set. So the software would not actually wait
long enough for the clock switch to happen, and would disable the PLL
while CPU was still clocked from PLL, leading to a halt.

This implementation uses rtc_clk_wait_for_slow_cycle() function to wait
until the clock switch, removing the need to wait for a fixed number of
CPU cycles.

Since 9a8c0392, XTAL frequency is set to 40MHz by default, and users
of 26MHz boards need to select 26MHz manually. Most users are not aware
of this change, and existing getting started guides do not mention that
XTAL frequency needs to be set for some boards. So users are left with
garbage output from UART without any clue what to check.

This change adds a warning in case specific XTAL frequency was set, and
it does not match automatically detected one. This should help users
fix the issue.

01b185977c brownout detector: enable by default
Because of errata related to BOD reset function, brownout is handled as follows:

- attach an ISR to brownout interrupt
- when ISR happens, print a message and do a software restart
- esp_restart_nonos enables RTC watchdog, so if restart fails,
  there will be  one more attempt to restart (using the RTC
  watchdog)

46fa2cfb46 Merge branch 'feature/spi_slave' into 'master'
Split common SPI stuff out of master driver; add slave driver; add workaround for DMA issue.

This merge req mainly adds a slave device. In order to do this, the original master driver is refactored into common code shared by master and slave modes, and a slave driver is added.

The other things added are:
- Added a workaround for a 'feature' of the ESP32 silicon that can lock up the receive DMA channel in some situations. This can only be fixed by resetting *both* DMA channels. The workaround implemented makes sure that the reset only happens when both channels are idle
- Got rid of the automatic choice between register- and DMA-based transfers. The master (and slave) code will now always go for a DMA transfer if a DMA channel is given, and always go for register-based transfers if no DMA channel is given.
- Add in a bunch of fixes for outstanding Github issues.

0fe765a977 Merge branch 'feature/32k_xtal' into 'master'
add support for 32k XTAL as RTC_SLOW_CLK source

- RTC_CNTL_SLOWCLK_FREQ define is removed; rtc_clk_slow_freq_get_hz
  function can be used instead to get an approximate RTC_SLOW_CLK
  frequency

- Clock calibration is performed at startup. The value is saved and used
  for timekeeping and when entering deep sleep.

- When using the 32k XTAL, startup code will wait for the oscillator to
  start up. This can be possibly optimized by starting a separate task
  to wait for oscillator startup, and performing clock switch in that
  task.

- Fix a bug that 32k XTAL would be disabled in rtc_clk_init.

- Fix a rounding error in rtc_clk_cal, which caused systematic frequency
  error.

- Fix an overflow bug which caused rtc_clk_cal to timeout early if the
  slow_clk_cycles argument would exceed certain value

- Improve 32k XTAL oscillator startup time by introducing bootstrapping
  code, which uses internal pullup/pulldown resistors on 32K_N/32K_P
  pins to set better initial conditions for the oscillator.

3323f31cfb soc: implement XTAL frequency detection
ROM code already implements XTAL frequency detection, but it uses the 8M
clock before the clock tuning parameters are initialized. With the
zero clock tuning parameter, 8M clock has significant frequency deviation
at high temperatures, which can lead to erroneous detection of 40 MHz
crystal as a 26 MHz one.

This change adds XTAL frequency detection code to rtc_clk_init routine,
and detection is performed after the 8M clock tuning parameter as been
initialized.

6e9d60ef70 rtc_clk_init: handle case when XTAL frequency has already been set
On first reset, ROM code writes the estimated XTAL frequency into
RTC_APB_FREQ_REG (aka STORE5). If the application doesn’t specify exact
XTAL frequency (which is always the case for now), rtc_clk_init will
guess what kind of XTAL is used (26M or 40M), based on the estimated
frequency. Later, detected frequency is written into RTC_XTAL_FREQ_REG
(aka STORE4).

When the application switches clock source to PLL, APB frequency changes
and RTC_APB_FREQ_REG is updated. If the application encounters an RTC
WDT reset, RTC_APB_FREQ_REG will not be updated prior to reset. Once the
application starts up again, it will attempt to auto-detect XTAL
frequency based on RTC_APB_FREQ_REG, which now has value of 80000000.
This will fail, and rtc_clk_xtal_freq_estimate will fall back to the
default value of 26 MHz. Due to an incorrect XTAL frequency, PLL
initialization will also take incorrect path, and PLL will run at a
different frequency. Depending on the application this may cause just
garbage output on UART or a crash (if WiFi is used).
