Re: [Gumstix-users] DSP issue: Translation Look-aside Buffers

[Chris W. <whi...@gm...>]

Did you edit uboot env to leave the memory hole for cmem?  Something like:

setenv mem 'mem=99M@0x80000000 mem=128M@0x88000000'

then put ${mem} in your boot args...

Then also, is the codec server located in /usr/share/ti on your target?

Then check is cmem module is loaded with lsmod.  I bet it is not,
since it didn't look like changed your uboot parameters.
