Hello all,
I'm trying to boot from RAM using SPL only.
(Another scp processor loads the FIT image to the SDRAM before starting
u-boot-spl is started)
Since the debugger doesn't work yet, I have to rely on prints to debug.
The printf works fine (I once asked about initializing serial port here, and
later found serial_init is done in board_init_f ).
I tried to make debug(xxx) printed to serial port but couldn't figure out
how to do it.
I tried
1. Adding #define DEBUG to the relevant source file
2. Giving DEBUG=1 in the make command (or CFLAGS=-DDEBUG)
But it doesn't work (of course I can change debug to printf to see it).
How can I make debug( ) macro output to the serial port?
Thank you!
Chan Kim

As the document said, I tried added "#define DEBUG" in each file but it
doesn't work.
If I add "#define debug printf" then, of course debug() is printed.
