Hi All,
This fix doesn't work with binutils-2.18. I'm building u-boot for the amcc yosemite board using cygwin and cross binutils-2.18/gcc-4.2.2 for a powerpc-eabi target.
Yes, binutils-2.18 have this broken. binutils-2.17 work fine.
The linker complains that "section .text can't be allocated in segment 0." The .bss section is by default a NOLOAD section with binutils-2.18 meaning it occupies no space in the file. However, the .bss section is an ALLOC section meaning it does occupy space in target memory. The linker runs an error check to make sure all sections will fit within the file and all sections will fit within target memory. All sections do fit within the file, however the sections do not fit within target memory because of the wrap around end of memory.
We could definitely drop the TEXT_BASE address lower which would fix the problem, but isn't ideal since the image would take up more flash for no reason. We could link with TEXT_BASE=0 and then burn it to flash at address 0xFFF80000 (this is where the current TEXT_BASE is for the yosemite board). Whats the reason it's linked at 0xFFF80000 anyway? Is there an elf loader which burns it into flash? There's also the 'AT' attribute in the linker script which may help, however, I don't quite understand the use of it yet. Any suggestions on how to approach this?
I am about to verify the latest binutils-snapshot. There have been the following patch included: http://sourceware.org/ml/binutils/2007-11/msg00235.html which should fix that issue.
Please be patient... I'll give you an update ASAP.
