In some cases, linker could choose to use ROM functions instead of the
ones defined in IDF.
For functions used in ROM stub table, this would lead to infinite
recursion when the corresponding function was called from ROM.
For crypto functions, some of these were modified in IDF, and
incompatible with ROM counterparts.
If zero-overhead loop buffer is enabled, under certain rare conditions
when executing a zero-overhead loop, the CPU may attempt to execute an invalid instruction. Work around by disabling the buffer.
Due to a hardware limitation in ESP32, the first four bytes of some
CSI data is invalid, not the last four bytes.
Correct a mistake of CSI sub-carrier index in documentation.
1. fix bug PHY/RTC functions called in ISR (update phy to v4007)
2. add UnitTest to test it
3. fix task watchdog bug when wifi change channel
4. disable/enable agc to mac deinit/init
5. add UnitTest Job
state and reduce force receiving broadcast data time
1. If receiving beacon which indicates that there is no data
buffered, do not force to receive WiFi data.
2. If receiving beacon which indicates that there is broadcast data
buffered, reduce the time to force receiving broadcast data.
timer_process_alarm function of esp_timer holds a spinlock for the
entire duration of its operation, except for the time when timer
callback function is called. It is possible that when
timer_process_alarm releases the spinlock, a higher priority task may
run and delete the timer. Then the execution will return to
timer_process_alarm, and this will either cause a crash, or undesired
execution of callback after the timer has been stopped or deleted.
To solve this problem, add a mutex which will prevent deletion of timers
while callbacks are being dispatched.
This fix includes following changes:
1. Fix the bug that esp_restart()/esp_wifi_stop() sometimes fails in WiFi/BT coexist mode.
2. Add a timer for WiFi stop and stop WiFi forcibly once the timer expires.
1. start an esp_timer on entering sleep to acquire pm_lock before wake up from modem sleep
2. decrease the clock division of XTAL fed to bluetooth low power clock from 32us to 2us period to allow to work under 240MHz Max CPU frequency
3. decrease the minimum sleep duration threshold to allow shorter bluetooth modem sleep period, especially for BLE with short connection interval
4. reconfigure bluetooth baseband(BT-BB) settings after PHY/RF init upon waking up from modem sleep to avoid packet RX/TX performance degradation
1. Fix interrupt watchdog timeout in bluetooth "btdm_bb_isr"
2. Fix BLE assert(512) or assert(1536) in rwble.c at line 222
3. Update librtc.a to fix BLE assert(512) in rwble.c at line 222
The #1 and #2 occurs random.
The #3 bug occurs in certain scenario:
1. If Wifi start softap and BLE is working
2. If wifi start station, but do not use normal station operation, such
as just use espnow, while BLE is working
3. Any other scenario, that wifi works without use software coexist
operation, while BLE is working(such as do advertising and ...)
4. update libcoexist.a version to v1.1.2
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.

Fix some wifi bugs
1. Enable RX BAR
2. Fix the bug that ESP32 AP negotiates with iphone to 11g
3. Fix the bug that ESP32 STA has ap_loss because CMCC AP contains two SSID
1. When WIFI task or other high priority task blocks the Bluetooth task, ACL RX buffer will use up, ACL RX buffer ptr will point to null and will never point to a valid adress. Causing errors in Bluetooth.
2. hcimsgs.h used whether flow control is on or off
1. resolve the error in calculating sniff anchor point that result in connection supervision timeout
2. resolve the issue of user case that requires sniff attempt is larger than 0xff
Fix following WiFi bugs:
1. Fix the bug that MIC verification fails on soft-AP mode
2. Modify mesh root to have same behavior as normal WiFi STA in state change
3. Fix the bug that sniffer can't catch control packets
4. Fix crash bug in soft-AP mode
5. Fix ACM(Admission Control Management) bug
1. fix some bugs by previous coex hw blocking bugfix,
such like, rwble.c (64, 0) line 222
2. fix bug that ble scan performance is very low when software coexist
is working.
3. update libcoexist version to v1.1.0
1. remove use EID to distinguish psram voltage
2. 1V8 64Mbit psram and 3V3 64Mbit psram use the same psram driver(standard spi interface)
3. set cs hold time register as 1
1. Add reading psram EID.
2. Configure different clock mode for different EID.
3. add API to get psram size and voltage.
4. Remove unnecessary VSPI claim.
For 32MBit@1.8V and 64MBit@3.3V psram, there should be 2 extra clock cycles after CS get high level.
For 64MBit@1.8 psram, we can just use standard SPI protocol to drive the psram. We also need to increase the HOLD time for CS in this case.
EID for psram:
32MBit 1.8v: 0x20
64MBit 1.8v: 0x26
64MBit 3.3v: 0x46
1. Fix the bug that ESP32 will reject the retry AddBA request frame
if AddBA response frame is failed to sent by WiFi LMAC
2. Fix the bug that AddBA request retrys too frequently
3. Forbid BA session setup for VO queue related TID
Routine `spi_flash_cache2phys` sometimes return incorrect value,
resulting in failure in getting currently running ota partition.
This in turn aborts firmware update process.This issue was more
prominent with SPIRAM enabled cases.
Fix ensures proper cache guards during `spi_flash_cache2phys`, and
also for few other similar APIs.
In addition, `esp_ota_get_running_partition` has also been optimized
to save currently running partition for subsequent invocations.
Fixes https://github.com/espressif/esp-idf/issues/2451
Problem Description
The reporduce steps are as follows:
1.This issue can be reproduced with 4 ESP32 devices, 2 for stations (STA1, STA2) and 2 for soft-AP (AP1, AP2)
2.Configure AP1/AP2 to the same SSID (ssid_xxx)
3.The max allowed WiFi connections of AP1 is configured to 1 and STA1 connects to AP1
4.The AP1 is close to STA2 while AP2 is far away from STA2 (but the STA2 can find the AP2 via scan)
5.STA2 connects ssid_xxx with all scan method
6.The problem will happen on STA2 because it fails to connec AP1 and never connects AP2
Phenmenon
STA fail to connect after send auth or assoc with a wrong status code, but no disconnect event report and can not connect the next one in the envrionment
Root Cause
Because there are some same ssid APs in the evnrionment, when do all channel scan, it will collect all the matched AP in rc list, because rc list is not empty, so it would send disconnect event, however, we didn't do other step such as connect to other one
VNC MR 575
closes https://github.com/espressif/esp-idf/issues/2323
fix the bug following:
1. after disable bluetooth controller, wifi cannot TX/RX any packets.
2. when software coexist working, there's a little ratio cause wifi task
watchdog timeout
3. when software coexist working, there's a little ratio cause bluetooth
cannot receive anything.
feature:
1. add libbtdm_app.a git commit local and remote checking
Known issues:
1. there's still a bug occurs with a very very low ratio cause bluetooth
cannot receive anything. The reproduce interval may great than 3days
~ 1week via 7x24 hours heavy testing.
