Hello.
I accidentally made this CPU's SWD (PIN 32, 33)
Programmed to I2C0_SCL, I2C0_SDA and written to the flash ROM,
DEFAULT: SWD
ALT5: I2C
Of course, debug connection with CMSIS-DAP is no longer possible.
As for the question, is there a way to revive this, that is, a writing method to make it the default SWD again?
Someone, please teach. Thank you.
P. S.
Sorry, my English is not good
Solved! Go to Solution.
You have to try to get control over the microcontroller right after reset before it does the pin muxing.
In MCUXpresso IDE there is a recovery option you could try:
An even better option is to use the P&E recovery tool. I have used that one sucessfully for the case you have, see Bricking and Recovering FRDM-KL25Z Boards: Reset, SWD Clock and Low Power | MCU on Eclipse
I hope this helps,
Erich
