While you might not be explicitly allocating much memory, probably codecs that
you're using are. You will need to increase the number of buffers of size >=
884736 for CMEM. Since your current pool configuration consumes all of the
12MB granted to CMEM, you will need to either reduce some of the pools or grant
more memory to CMEM.
One possibility is to simply increase the pool buffer size that currently is
configured as "7x829440". You should have enough room in your CMEM memory to
change 829440 to 884736.
If that doesn't do the trick for you, you will need to get some idea of your
CMEM memory needs. One way to do this is to set the CMEM module's debug flag
to true in your application .cfg file:
var cmem=xdc.useModule('ti.sdo.linuxutils.cmem.CMEM');
cmem.debug = true;
It looks like you're already doing this (or some other module is doing this for
you), since you listed CMEM debug in your original email. Take a look at the
allocation requests to CMEM, and match your pool allocations accordingly.
