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

[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.
