Hi guys,

I'm looking for a way in uClinux/uboot to enable the L1 d-cache pointing to L2 (not the DDR). It should work similar as the following code with VDSP:

{0xFEB00000, (PAGE_SIZE_1MB | CACHE_MEM_MODE | CPLB_LOCK)};

Thanks,

for now, you need to edit cplbinit.c by hand. you can find it in linux-2.6.x/arch/blackfin/. there will be a L2 cplb entry in that file.
