Re: [microblaze-uclinux] Unable to allocate RAM for process text/data

2007/9/11, Benny Chen <bennyc@xxxxxxxxxxxxxx>:

Hi Nicho,
To fix your problem, you need to use the SLAB memory allocator instead
of using the SLOB allocator.  The SLOB allocator does not work.

Under "Configure standard kernel features (for small systems)" submenu
in make menuconfig, enable the "Use full SLAB allocator" option.

Cheers,
B.
