i recently purchased 6 xiao esp32c3 boards and when i went to use them, nothing was happening, after some testing, i have found that of the six boards i bought, only one of them will actually run the code i upload to it. the rest will receive the code from arduino ide without issue, but then don’t execute it. i have tried reflashing the bootloader to two of them but the problem persists
Hi there,
Welcome here,
I would try the blink program first before rewriting any bootloaders
If you put them in bootloader mode it should download aok and you may have to press the reset manually after. (some serial ports do not reset the DFU mode correctly RTS/DTR )
