Hello!
Current u-boot from master branch does not work on n900 hw. It does not show anything on display, there just nokia logo.
In qemu it is working fine and all tests are passing. Also in qemu is display working without any problem.
Could you help me to debug it? Maybe something is printed to serial console? Or maybe serial console could be used for printf-debugging?
I just figured out that disabling CONFIG_POSITION_INDEPENDENT u-boot option make it working again. But it requires to restoring older version of lowlevel_init.S file which does not depend on POSITION_INDEPENDENT:
git checkout 7c4ad9821758f98db127e9d6864671c906c02d3b -- board/nokia/rx51/lowlevel_init.SAnd also setting CONFIG_SYS_TEXT_BASE=0x80008000 (to some value in RAM).
Hi
I have a really crude serial console setup in place now, but very little time, and even less experience with u-boot. I should be able to do the tests for you on Saturday night (UTC+2). Perhaps over IRC might be a good idea, in case I need some hand-holding, and if you still need the help by then.
