unable to flash after loading arduino tetris



  • gray m5 core

    Win7 - loaded tetris from arduino UI successfully. no trying to re-flash anything from arduino or m5burner it looks like the tetris load does not let the bootloader start. on any load attempt the system resets and then the tetris start screen appears. this repeats till the loader times out trying to connect. forcing a reset via the power button has no difference than the usb induced reset



  • from arduino serial monitor @ 115200 baud :

    M5Stack initializing...OK

    so the serial port seems to be working OK - but loader never connects



  • solved...sort of ... looks to be win7 problem - works fine on up to date win 10


  • M5Stack

    @daavery You can try more times on win7, maybe just baud rate issue or USB COM / cable issue.
