Hi everybody,
I'm in the process of writting PCMCIA support for WEPEP250 (boards/wepep250). Everything seems to be going smooth except one thing:
When I add a debug function and then execute U-Boot command "pinit on" or "ide reset" U-boot hangs on me. I sometimes get "data abort", sometimes "invalid instruction" and sometimes nothing.
Is there any limits with regards to U-Boot's size and by me putting too much inside U-boot's .text section and hitting some marker/border ?
The situation: ident_cpy() function used in ide_ident() copies firmware, version, ident string from iop structure to dev_desc structure. Since CompactFlash firmware string and model number string are in big endian byte order I wanted to write ident_swap_cpy, but as I wrote the function, re-compiled U-boot, downloaded it and issued "ide reset" I got a hang. I also tried to put just two printf's inside ident_copy() - a hang again.
ident_swap_cpy() worked fine when I compiled and ran it in my examples/ide.c file.
Thanks,
