- In SPI mode, the card will respond to the initial SDIO reset (done
using CMD52) with “invalid command” error. Handle this correctly.
- sdmmc_card_init had a hack where GO_IDLE_STATE (CMD0) command was
sent twice. Add explanation why this is done, and don’t expect
correct response from the card on first CMD0.
- improve logs printed at debug level by adding CMD index
- Add SDIO support at protocol layer (probing, data transfer, interrupts)
- Add SDIO interrupts support in SDMMC host
- Add test (communicate with ESP32 in SDIO download mode)
Existing code assumed that response timeout is not followed by CMD_DONE,
which was not true, in fact. Host datasheet states that CMD_DONE is sent
after an RTO.
All the commands which do not have a response must have their flags set
accordingly. Therefore the host will not send RTO interrupt if response
is not expected. It is a bug in the code logic if it happens otherwise.
SDMMC host suffers from an issue that it outputs data near the rising
edge of the card clock, which is the edge used by the card to sample
data. If sampling time constraint is not satisfied, card may read data
after the transition.
The phases of output/input data can, in fact, be adjusted. However this
adjustment happens in the clock generation block outside of the host.
So the maximum phase change which can be created this way is equal to
half of the host clock period. So if the host clock is set to the lowest
possible frequency (for the given card frequency), then the phase offset
(and hence the hold time) will be the highest. This change modifies the
logic used to determine clock dividers accordingly.
sdmmc host: set correct dout phase and print correct frequency
SET_BUS_WIDTH is not a data transfer command. Extensive search in the
host datasheet and SD card spec did not reveal the origin of this hack
or 'feature'. Further testing showed that removing this does not lead to
regressions.
Fixes exceptions LoadProhibited, when rmt tries read variable p_rmt on RX END which can be 0.
It happens after esp_reset() (OTA) and the rmt is not probably stopped by it.
In other words the routine rmt_driver_isr_default was called before second rx channel was registered.
scenario:
register tx channel
register rx channel
reboot
register tx channel
-> exception (because rx channel is accessed)

- In some cases where the HTTP URL contains the port number
(http://hostname:334), the DNS querier fails to resolve the hostname.
- Hence we have to populate the port number ourselves.
- This can only be done based on whether we get an IPv4 or IPv6
address.
Purpose:
1. TLS calls can be too many, and require a user to know the expected behaviour. A simple TLS socket wrapper that can be used in any higher level protocol.
2. Uses OpenSSL compatibility layer, so applications using esp-tls can be built on the host, and it should just work on ESP
Strips leading ../ when generating object file paths, keeps these in sync with the source files
otherwise.
This prevents object files landing in other directories, including outside the build directory, if
the component_srcdirs start with ../
When splitting a memory block, check if the next block is free.
If it is, then just extend it upwards instead of creating a new block.
This fixes a bug where when shrinking existing allocations would result in irreversible free space fragmentation.
When testing on the host, test all the poisoning configurations.
SDSPI driver optimized polling of the response tokens by requesting
two extra bytes on top of the block size (512) and CRC (2), and
checking whether these bytes contained the data response token or
not. In case the token was there, further polling would not need to
happen, thereby reducing latency between two consecutive blocks
transferred. However this caused compatibility issues when these two
extra bytes were sent after reading the final block. When
STOP_TRANSMISSION command was sent, these extra two bytes were
treated as part of the command, causing an invalid command error.
This fixes the logic by only requesting extra two bytes if the block
being read is not the final block. In addition to that, more strict
error checking is implemented for command response tokens.

Some application lock interrupt(portENTER_CRITICAL) too long time,

It is not possible to generate 1 MHz REF_TICK from 2 MHz APB clock
(this is a limitation of REF_TICK divider circuit). Since switching
REF_TICK frequency is something we would like to avoid (to maintain
UART output even with DFS), 2 MHz frequency has been marked as
unsupported.
The issue would manifest itself in cases when switching from PM
configuration like {active=160MHz, idle=80MHz} to {active=80MHz,
idle=80Mhz}. After the configuration was changed, PM logic would
think that current frequency was 80MHz and would not do any further
switching. In fact, frequency was still 160MHz.
The old code calculated MAX() of two enum values, but CPU frequency
enum values are not ordered (2MHz goes after 240MHz). This caused
incorrect configuration to be set.
Previous code contained a check for PLL frequency to be 240MHz, while
in fact 240MHz was a CPU frequency; corresponding PLL frequency is
480MHz. Fixed the comparison and replaced integer MHz values with an
enum.
This commit adds character encoding configurations in for the fatfs component.
The FF_LFN_UNICODE definition in ffconf.h can now be changed to accept UTF-8 or
UTF-16 encoded filernames. Test cases using UTF-8 encoded file paths and names in
FatFs have also been added.

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.

If the inherit flag is set, then all subsequent threads forked by this

d0e55335 Component/bt: fix reconnect fail in smp
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.
- separate mode stats from lock stats by an extra comment line
- add CPU frequency column to the mode stats
- don’t print a row for light sleep if light sleep is not enabled
s_cpu_freq_by_mode array was statically initialised with 80MHz CPU
frequency in CPU_MAX and APB_MAX modes, but sdkconfig setting for the
CPU frequency could have been different. For the case of 240MHz CPU
frequency, this would cause a frequency switch between 240MHz and
80MHz to happen, even though such switch is not supported in the fast
path switching functions used by the DFS implementation.
This fixes the issue by moving initialisation into esp_pm_impl_init,
which is called at startup before the first mode switch can happen.

On most microcontrollers I have worked with one can retrieve the
current state of output GPIO pins. On ESP32 this is not the case
if the pad is not explictly configured to route this information into
the port by configuring it as input or i/o.
