9e2103f27e Patch eap.o memory leak (#8566)
* Patch eap.o memory leak

WiFi Enterprise option can leak up to 3 allocations per connect/disconnect
cycle: anonymous Identity, password, and some unidentified allocation.

This solution patches eap.o from libwpa2 to call a special 2 part
wrapper instead of vPortFree for cleanup.

Corrected typos and adjusted tabs in script.

Added script eval_fix_sdks.sh to aid in evaluating similarity between
patch sections of .o files being patched across different SDKs.

* Add some dev debug code and improve comments

f5ef02d643 Fix double-free when connecting to WPA2-Enterprise networks (#8529)
* Fix double-free when connecting to WPA2-Enterprise networks

Fixes: #8082

This patches the callx0 instruction to a nop in eap.o which is part of libwpa2.a.
It looks like espressif fixed the Bug in newer SDK versions, so if we update to the latest NONOS-SDK it is most likely not necessary to add/adapt this patch.
Also modifies the fix_sdk_libs.sh script as it even changed files if no changes were necessary, for example adding multiple system_func1 exports.

* Apply suggestions from code review

83f5f29cfd Support to reboot into UART download mode (#7854)
without any external wiring.

This patch introduces the new method
Esp.rebootIntoUartDownloadMode()

When the user calls this method the ESP8266 reboots into the UART
download mode. In this mode the user can use esptool.py to flash a new
firmware file. The following command was used to test it:
$ esptool.py --before no_reset --after soft_reset --chip esp8266 \
    --port /dev/ttyUSB0 --baud 460800 write_flash 0x0 firmware.bin

The implementation is based on the original implementation in the
boot ROM. Some parts of the original implementation can be found in
[1]. This patch is a squashed and simplified version of [2]. The non
squashed version might be helpful in case of debugging issues.

e56aed6540 remove unused upstream library (#6456) 2019-08-27 02:12:47 +02:00
7745e99046 Revert to nonos-sdk 2.2.1, new sdk-switching option in IDE menu for generic board only (#5763)
This commit allows switching SDK firmware:

nonos-sdk-pre-v3 shipped with release 2.5.0 has issues:

    * Some boards show erratic behavior (radio connection is quickly lost), with an unknown cause.
      These boards work well with previous nonos-sdk-2.2.1 firmware (#5736)

    * Overall performances seem to have decreased (#5513)

This PR restores sdk2.2.1 (as in core-2.4.2).

SDK-pre-3.0 - which has brought long awaited fixes (WiFi sleep modes) - is still available through a menu option available only with generic board.

BREAKING

    * new define `-DNONOSDK221=1` or `-DNONOSDK3V0=1`

    * for external build systems: new library directory: `tools/sdk/lib/<version>/lib`

    * PIO: variable `PIO_FRAMEWORK_ARDUINO_ESPRESSIF_SDK3` is needed for sdk-pre-v3.


Fix #5736
