1. add enable PSRAM 2T mode function
2. abort when himem and 2T mode are enabled meanwhile
3. set SPIRAM_2T_MODE as "n" by default, enable it when needed
Backport following Wifi fixes:
1. Fix esp_wifi_stop() crash
esp_wifi_stop() crashes if it's called when WiFi is not initialized.
2. Fix memory leak caused by esp_wifi_stop()
3. Fix WiFi log print level
4. esp_wifi_sta_get_ap_info() returns actual values of group ciphers
1,Fix sniffer bug caused by mode switch
2,Reduce WiFi bin size
3,Add TX packets size check
4,Fix scan get rssi error
5,Add wifi stop check at WiFi deinit entry
6,Return fail when setting AP's channel is out of range
7,Fix the bug for setting channel when WiFi in NULL mode
Fix an error of mesh deinit lock.
Fix mesh send returns TIMEOUT.
Increase root window close time to 120s.
Clear ie.child when the child connected or fully associated.
Update rc_rssi when roots direct/forward.
ix assoc in mesh ie wrong.
Mesh packets use AC_VI instead of AC_BE.
1. Fix WiFi scan leads to poor performance of Bluetooth.
2. Improve WiFi connect success ratio when coexist with Bluetooth.
3. Check if WiFi is still connected when CSA or beacon timeout happen.
4. add coex pre init
1,Fix wifi block scan crash issue.
2,Fix association request RSN information length too big lead crash
3,Fix wifi stop bug when sniffer enable
4,coex:fix wifi scan and connect bugs
5,Fix some wifi timer bugs
6,Fix wifi RX bug
7,Fix the bugs for bandwidth
8,Fix the bug for espnow
9,Fix AMSDU decrypt bug
10,Fix wifi reload issue
arg1 = MAX(int64_t arg1, uint64_t arg2) gave the wrong result, if arg1 < 0, it was presented as a larger value.
And ALARM_REG = (uin32_t)arg1. This leads to an infinite loop.
Fixed: both args are int64_t.
Closes: WIFI-1511
Sometimes, libphy.a call phy_enter_critical() to protect accessing critical sections, such like
operating on I2C, but it may not effect when both the CPU core call it. It may cause accessing
I2C blocking and cannot recover by esp_restart(), until do HW reboot.
1. Fix high beacon and broadcast packets loss ratio of WiFi to make
MDNS test pass.
2. Improve stability of WiFi performance with a little
sacrifice of throughput.
3. Improve BLE advertising and connection performance with dynamic
priority. It sacrifices a little WiFi throughput, but achieves balance
between WiFi and Bluetooth.
Fix following WiFi bugs:
1. Fix the bug for API_CHECK_ENABLED
2. Fix the bug that wpa2 enterprise sta can connect open AP
3. Fix TKIP/CCMP PN replay attack detection bug
4. Increase buffer number type from uint8_t to uint16_t to support more than 255 buffers
5. Avoid recalculating PMK if esp_wifi_set_config() is not called
6. Fix the bug that WiFi stop leads to task watchdog
7. Fix smartconfig IPC crash
8. Fix the crash bug that sniffer may access flash when cached is disabled
9. Fix 5.5M signal test bug
We fixed some flash bugs in bootloader, but for the users used the old
vrsion bootloader, they can not fix these bugs via OTA, the solution is
add these updates in app startup.
These updates include:
1. SPI flash gpio matrix and drive strength configuration
2. SPI flash clock configuration
3. SPI flash read dummy configuration
4. SPI flash cs timing configuration
5. Update flash id of g_rom_flashchip
1. fix bug bb reset lock flag to avoid bb reset lock unhandle,
may cause assert in vPortCPUReleaseMutexIntsDisabledInternal.
2. fix bug wifi reset mac cause task watch dog timeout
3. fix bug wifi reset mac position
