- Thu Jun 23, 2016 11:55 am #49671 According to the pin function chart below, the default function of GPIO2 is IO.



Does debug change the pin function of GPIO2? Would reassigning the pin function eliminate the problem of debug writing to TX? The pin could be disconnected when flashing, but used as GPIO input after normal boot (run mode).

Code: Select allPIN_FUNC_SELECT(PERIPHS_IO_MUX_GPIO1_U, FUNC_GPIO1)
