ESP32-S3-DevKit support

Posted on
  • Hello there!

    I tried to flash espruino on my S3 dev board, which seems to work:

    ./esptool --chip auto --port /dev/ttyUSB0 --baud 115200 --after hard_reset write_flash -z 0x1000 ../espruino_2v01.29_esp32/bootloader.bin­ 0x8000 ../espruino_2v01.29_esp32/partitions_esp­ruino.bin 0x10000 ../espruino_2v01.29_esp32/espruino_esp32­.bin

    However, it does not boot:

    Invalid image block, can't boot.

    I didn't find any documentation related to ESP32-S3, so here I am asking if it's supported.
