I did some more tests.
When I do build unmodified qi, flash the image, it runs fine.
But if I insert a single puts() line in src/cpu/s3c2442/start_qi.c :
start_qi, just after qi info is printed and before
bootloader_second_phase is called, it hangs and prints Ts.
Two things. You are not in stepping stone size or just you don't have
register
what function must use puts. set_putc_func.

Can you post your diff?
This is the only difference except for config.mk:

here is the stepping stone,do you have change any of these file? and add
code,
You have only 4kb :)
I have modified start_qi.c only. Object files are clearly larger than
4kb. I do not understand this low level stuff well...
The take only few section, I don't think it's larger. BTW you can remove
for example
the memory-test object and having more space to add puts, or remove some
puts and
see what happen.
My goal is to add debug prints to nand reading code. What is the right
way to do this without breaking the 4kb limit?
