Hi , i'm having a connection through UART and i use serial.swap()
to change the pins of UART for having communication with another device . ( i cant use original pins because of problems with Serial programming whitch causes the 2nd device to crash )
after i use serial.swap()
the 2 pins for UART are GPIO13 and GPIO15 .
but we should pull-down GPIO15 for booting up from flash ...
how can i use the second UART pins but also making sure that if my module resets it will boot up from flash (and not from SD-Card ) ?
