Part Number: AM5728

Tool/software: Linux

Hello

I'm using am5728 with procesesor sdk 5.02 where u-boot is 2018.01.

i've found some threads that says adding

#define DEBUG in include/am57xx_evm.h can enable debug() output in spl.

so i've added it at line 15 but it seems doesn't work.

I can't see any output on serial.Do i need to change any other settings if yes please suggest one or provide any better way.

Thanks

Hello,

I defined "#define DEBUG" in the file "<u-boot>/include/configs/am57xx_evm.h" (line12). Next, using the top level Makefile, I compiled the uboot and copied the new images to the SD card. I was able to see the debug messages on the serial console.

Well my bootloader stuck before preloader_console_init() so it seem this define doesn't works.
This define will work for debug() after preloader_console_init() executed.
