I was trying to load a image onto am437x hs custom board with GPIO1[6] enabled for driving RS485 where this pin is enabling RS485 driver IC(DE) connected to PRU UART.
After compilation and loading of image, I enabled the GPIO1[6] using /sys/class/gpio. Once that is enabled the board is not getting booted at all.
With SD card or SPI we are not seeing logs. Now we want to debug this issue, Is there any mechanism to debug this issue other than booting board with u-boot and spl.
