ESP32S2 compiling issues

[mtk11]

I have tried to compile the esp32s2 branch, but getting the following errors::

C:\Marlin\Marlin-esp32s2\Marlin\src\HAL\ESP32\timers.cpp: In function 'void timer_isr(void*)':

Error compiling for board ESP32S2 Dev Module.

Also, any intention to port Marlin to esp32s3 ?

I am building this project for a controller I have designed myself with an espressif esp32-s2. I'm using both VSCode + PlatformIO and the Arduino IDE, and on both I have compile errors:
