hello everyone,
Franck from France.
Thank you Olimex for your quality products that I use since 2016, like your ARM AXX are still running for years, same way  : EVB/first ESP8266 is still Alive.
For the first time ,i can't reach a flash positive result with an industrial ESP32-S2 on Micropython.

I took the Espressif doc ESPTOOL to do it without success:
Erase Flash then Flash with ESPTOOL ->

esptool --chip esp32s2 -p COM5 -b 115200 --before=no_reset --after=hard_reset write_flash --flash_mode dio --flash_freq 40m --flash_size 4MB 0x1000 c:\olimex\ESP32_S2_WROVER-20220116-unstable-v1.17-333-gcf258c898.bin

Note: i test every image address  0x1000 and 0x0 and DIO frequency ...

So i missed something and need  a hand :)
Perhaps Someone have already install Micropython on this S2 board : I'm stuck!
