RE: [microblaze-uclinux] uclinux memory exhausted, unable to allocate RAM
Hi,
After I increase the program size to 700KB, I get a different error, which says BINFMT_FLAT: reloc outside program.
I have compressed the program, and use "permit large allocations" setting in the kernel. I searched the mailing list, but I could not get an answer.
Thanks,
Victor

In menuconfig -> kernel settings -> general settings, try enabling
either the "Permit large allocations" setting, or the "non-power-of-2"
allocator.
