I am trying to modify the bootloader and to debug the bootloader I wanted to add the debug messages. But I am anot able to do this as enabling
“#define BOOTLOADER_DEBUG SDU1” in support.cpp file is giving compilation warning.
from the following macro
#define BOOTLOADER_DEV_LIST (BaseChannel *)&SDU1,(BaseChannel *)&SD2,(BaseChannel *)&SD3,(BaseChannel *)&SD7
Please suggest how to enable the debug statement and making this USB port for debugging.
