The bug will cause memory corrupted (the largest range is from 0x3ffc0000 ~ 0x3ffc8000),
some strange error will happen, like IllegalInstruction, LoadProhibited and .etc.
1. esp32-pico use standard spi driver to access psram
2. for esp32-pico, flash and psram share the clock
3. for esp32-pico, psram cs io can be overwrite via menuconfig
1. Use BIT[7:5] of EID to determine psram size
2. Add ID support for 16Mbit psram
3. Remove module reset on SPI1
4. Confirmed with the vendor that only the old 32Mbit psram need special clock timing. For other psram chips, we should use standard QPI mode.
Files where stack protector is initialized should not be compiled with
stack protector enabled. This was done for Make but missing for CMake.
Fixes https://github.com/espressif/esp-idf/issues/2990.
Fix following WiFi bugs:
1. Fix a crash bug which is caused by WiFi static TX buffer alloc/free.
2. Fix the bug that iphone fails to connect to ESP32 AP by enabling AP BAR receiving.
3. Fix the bug that ESP32 station fails to connect some APs, such as Xiaomi hotspot etc,
after reset.
This commit adds the ability for backtracing to trace from the itnerrupt to the
task stack, and across nested interrupts. Test cases have also been added.
See MR !4084
1. fix network channel switch function.
2. support not configuring the network channel.
3. support not configuring the router BSSID even if the router is hidden.
4. add allow_channel_switch to mesh configuration.
5. add allow_router_switch to mesh router configuration.
6. support handling beacon without IE of DS Parameter Set.
7. fix Wi-Fi RX fails in a specific scenario (update libphy.a).
8. fix STAs can not detect disconnection from AP when encrypt transmission is used.
9. fix can not find hidden APs.
10. for root, modify the active scan time to 120ms.
11. remove all rc when clear parent Wi-Fi configuration.
12. fix memory leak caused by the remove announcement being sent is not released when esp_mesh_stop() is called.
13. fix modify IE encrypt after mesh is started.
14. ignore esp_mesh_connect() if mesh automatic reconnection is enabled.
15. fix reason is cleared before vote is done.
16. fix issues in the example of manual_networking when mesh network is encrypted.
17. detect and fix root conflicts when router BSSID is not set.
18. when root can not connect to the router due to NO_MORE_STAS(reason code:5), root will stop re-connection and perform MESH_NWK_LOOK_FOR_NETWORK.
19. wifi: fix the disconnection caused by receiving a deauth frame from non-parent node during scanning.
20. fix routing table redundant issue due to the remove announcement is not 100% reliable.
21. modify the max routes limitation from 300 to 1000.
22. wifi: fix ap does not deauth the sta which has not yet completed the 4-way handshake but the max replay count is reached.
Previously, hardware SHA engine "locks" were mutex semaphores. This meant that the task which
started a particular SHA session (in hardware) needed to finalise that session, or an invalid
FreeRTOS state was created.
Replace with binary semaphore which can be shared between tasks.
Includes a unit test, but unit test doesn't crash even without this fix
(some other unknown condition is required).
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
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
