All peripheral clocks are default enabled after chip is powered on.
When CPU starts, if reset reason is CPU reset, disable those clocks
that are not enabled before reset. Otherwise, disable all those
useless clocks.
These peripheral clocks must be enabled when the peripherals are
initialized and disabled when they are deinitialized.
The code in xtensa_vectors.S did not handle XT_DEBUG_BACKTRACE
consistently: #if was used in one case, and #ifdef in another. This makes
the checks consistent, and also introduces a Kconfig option to enable
backtrace.
In some cases, xPortGetCoreID was not inlined, and ended up in flash.
Since this function is used in many situations when cache is disabled,
that caused exceptions. Adding IRAM attribute to fix that.
vfs_uart used same locks for read and write operations on a single UART.
If read operation was blocking (i.e. carried out via UART driver), the
lock was held by reading task until it received a line. During this time,
other tasks trying to write to the same UART would get blocked.
This change introduces separate read/write locks, and adds a test.
Another vfs_uart test if fixed (it was disabled since the
CONFIG_NEWLIB_STDOUT_ADDCR option was removed).
If two different types of SHA hashes were active in the hardware
concurrently, a race condition meant the SHA unit could be incorrectly
reset leading to all-zero results.
If scheduler switches cores in narrow window during esp_dport_access_stall_other_cpu_start(), could cause the stall
interrupt to occur on the running CPU - halting the CPU until WDT cleans up.

This commit adds support for multiple NVS partitions. This provides application a flexibility to have multiple NVS
partitions such as separate partition with read-only manufacturing data and read-write partition with configuration.
Application can also use this to separate out application's configuration storage from system configuration.
This feature does not change any of the basic property of NVS subsystem. The same-named namespaces across partitions are
considered to be different namespaces. The original NVS API available for the applications remains unchanged. The only
difference is that instead of first NVS partition in the partition table, it now operates on the partition with label
"nvs" (which is default in the IDF provided partition table files). Additional APIs are provided to open a handle and
erase NVS with partition name as a parameter.
A test case is added in the host tests and it is made sure that all the host tests pass. nvs_rw_value app is also tested
with multiple partitions.

We had already updated to v1.24 months ago, but the submodule commit was accidentally
reverted in 1fb85b494c.
Fixes (again) error when compiling with assertions disabled.
As reported on forum: https://esp32.com/viewtopic.php?f=13&t=2750&p=13069
component/bt: cherry-pick the bugfix/btdm_api_manage_pair_info_#13119 to this branch.
component/bt: Change the ble gap API code format & added the status judgment in the btc_storage_load_bonded_ble_devices function.
Previously VFS driver for UART could only use simple non-blocking
functions to read from and write to the UART. UART driver provides more
complex blocking and interrupt-driven functions, which can be used
instead.
This commit adds optional support for using UART driver's functions.
Also added is a more flexible mechanism for configuring newline
conversion rules on input and output.
This commit also fixes a bug that all UARTs shared one static variable
used as a character buffer in newline conversion code. This variable is
changed to be per-UART.
* Disables 3DES, Camellia, Blowfish, RC4, RIPEMD160, SSLv3, TLS-PSK modes, DTLS by default
* Saves about 40KB from the default TLS client code size
* Defaults no longer get "Bad" howsmyssl.com rating (no more vulnerable 3DES)
(ping https://github.com/espressif/arduino-esp32/issues/575 )
* Allows up to another 20-30KB code size to be trimmed without security
implications if using DER formatted certificates, RSA ciphersuites only,
etc.
* Can save up to another 8KB by setting the TLS Role to Server or Client only.
1. Hello World application shows no footprint difference before and
after this change
2. examples/ethernet/ethernet application compiles properly (can't
test with my board)
By default SD cards are initialized in default speed (DS) mode. Enabling
HS mode requires SWITCH_FUNC command to be sent twice: first time to
query if the card supports switching to HS mode, second time to perform
the switch.
This change implements SWITCH_FUNC command and adds the procedure to
switch to HS mode.
In some cases the card needs to be returned to standby mode from data
transfer mode. This is done using CMD7 command, which does not receive
any response in this case.
‘make_hw_cmd’ function checks opcodes in a few cases. Comparing opcode
does not tell the whole story, because for some SD commands there is are
APP commands with the same opcodes. This change introduces a flag which
indicates whether the next command is going to be an APP command.
The check for APP_SET_BUS_WIDTH command is updated to use this flag.
This fixes a bug with an unexpected STOP_TRANSMISSION command sent after
SWITCH_FUNC command, which has opcode 6, same as APP_SET_BUS_WIDTH.
MMC_RSP_BITS helper function had a hack that it flipped word order in
the response, assuming that response size is 4 words. This hack does not
work for responses which are not 4 words long (such as the SWITCH_FUNC
response, which is 64 words long).
This change removes the hack and the matching word order reversal code
in sdmmc driver.
Remove wifi config option
Remove Wi-Fi enable/disable option from Kconfig. This can be detected by the presence of esp_wifi_init() function in the application. Minimum footprint impact after the change.
See merge request !1098
This is no longer required since the functions automatically get
pulled in based on the usage. A quick summary of footprint
comparisions before and after these set of patches is shown below:
Hello-World: (simplified for readability)
old Total image size:~ 104902 bytes (.bin may be padded larger)
old Total image size:~ 105254 bytes (.bin may be padded larger)
Per-archive contributions to ELF file:
Archive File DRAM .data & .bss IRAM Flash code & rodata Total
old libesp32.a 1973 177 4445 3939 2267 12801
new libesp32.a 1973 185 4473 3939 2267 12837
new libnvs_flash.a 0 92 0 274 8 374
new libstdc++.a 0 0 0 24 0 24
For some reason, nvs_flash.a (~400bytes) gets pulled in (particularly
the nvs_flash_init() function).
Power-Save: (simplified for readability)
old Total image size:~ 421347 bytes (.bin may be padded larger)
old Total image size:~ 421235 bytes (.bin may be padded larger)
old libtcpip_adapter.a 0 81 0 1947 115 2143
new libtcpip_adapter.a 0 69 0 1897 115 2081
The size actually shrinks a bit, since the AP interface function
doesn't get pulled in.
Since only the used interface's start function gets called, it pulls
in only the functions that are required in the current application,
thereby saving footprint.
Restart being a lower-layer system-level function, needn't depend on
the higher level Wi-Fi libraries.
This also enables us to get rid of one more WIFI_ENABLED ifdef check
The address field should be placed at the highest bits of address and slv_wr_status registers. Instead of breaking the address into two parts and fill in each register, move the address to the highest bits and write to the registers respectively.
Breaking change: if you fill-in the SPI address filed in a previous version in some way and it works correctly, you still have to rewrite the address, in a more intuitive way.
force rxlength=length and mosi=1 and inlink.start=1 on in full-duplex mode.
set rxlength > length is forbidden in full-duplex mode.
