Hello again,
I'm leaving the problem description below, what fixed it all here was to add -fPIC to the CFLAGS to instruct the compiler to generate relocatable code (again).
This flag was replaced in commit 92d5ecba47feb9961c3b7525e947866c5f0d2de5
Did you reach tis commit by dissecting?
with -pie in LDFLAGS, which I don't understand (does not mean I have much experience how the compiler and linker are working in regard to relocatable code).
Regards,
Alexander
That needs some more analysis.
-fPIC without GOT relocation does nothing good, and with it, does not enough -- hence the ELF relocation patches replacing -fPIC with -pie, which is *intended* for relocating executables. these two machanisms are not meant to be used together.
Can you be more specific about this:
To verify the problem:
Add
#define DEBUG
in top of arch/arm/lib/board.c
and
printf("nand_chip: %p\n",,&nand_chip[0]);
in nand_init() in drivers/mtd/nand/nand.c
and have a look at the output when u-boot comes up.
Precisely what is the output in both cases?
Regards,
Alexander
Amicalement,
