  • OK. 1v96 might work too. I initially had to flash to 1v96 then up to 1v97.

    However, I've included here some files here that I built today (through the help of Wilberforce) for version 1v99 that resolves problems for me on a board with a 26mhz crystal. It might work for you.

    Also use "40m" for "--flash_freq" in your esptool, in addition to erasing the flash memory first.

    Like this,

    esptool.py --port  /dev/cu.usbserial-DN02MPA4  erase_flash
    

    then

    sudo esptool.py --chip esp32 --port "/dev/cu.usbserial-DN02MPA4" --baud 921600 write_flash -z --flash_mode "dio" --flash_freq "40m" 0x1000 bootloader.bin 0x10000 espruino_esp32.bin 0x8000 partitions_espruino.bin
    

    Let me know if it works, I'm curious.
