Joaquim,

Thank you for bringing this to our attention; we are looking into this.

One of our engineers recently provided the following information to another customer asking a similar question. This information was verified by the customer to have fixed their issue.

It looks like the initial error is a memory allocation failure because cmem doesn't have space to allocate a buffer of size 0x04900000 (76MB). The segmentation fault appears to be a follow-on error in cmem (likely due to an untested code path).

The default Logic PD BSP reserves space from 0x83700000 to 0x88000000 in the kernel command line, which provides 0x049000000 (76MB) of space for use by the DSP. CMEM is given 0x02200000 (35MB) of this space (as noted in the kernel log), leaving 41MB of space reserved for the DSP codecs (which have hard-coded memory addresses in them). Specifically, the cmemk module is loaded as follows:
modprobe cmemk phys_start=0x83700000 phys_end=0x85900000 allowOverlap=1 useHeapIfPoolUnavailable=1

If you want to use C6Run, I think you want to change the CMEM allocation to use the entire 76MB (since you are not using the pre-built DSP codecs). The script that loads the cmemk module can be found in /etc/rc.d/init.d/cmem, which is created by dist/lfs-5.1/ti-linuxutils-mod/ti-linuxutils-mod.spec . I think you want something like the following:
modprobe cmemk phys_start=0x83700000 phys_end=0x88000000 allowOverlap=1 useHeapIfPoolUnavailable=1
