HI,

Is it possible to change defult state of the GPIO pins(in bootloader mode)?

During bootloader mode, GPIO 51 held in LOW. is it possible to change to high or tristate?

Regards,

Malik

Hi Malik,

No its not possible to change the ROM bootloader so you can't change the state of GPIO, But you can go for 2nd stage bootloader in which you can control the state of GPIO pins.

Thanks & Regards
