Hello,
Last September we found a bug on ti-ipc MessageQ implementation that
caused some messages getting lost [1].This bug was fixed on the ipcdev
git repo a while ago [2]. However, this fix hasn't made it yet to any
MCSDK release. The current version of ti-ipc on MCSDK 3.0.3 is
3.00.04.29. This is also the version which seems to be used in the
upcoming 3.1 release...
We have cherry picked that fix and it seems to work OK. However, we are
still experiencing some issues with the IPC communication (some messages
from the DSP to the ARM core get corrupted). Before spending time
debugging this, we would like to try upgrading the ti-ipc package, since
there seem to be quite man other bug fixes and changes since version
3.00.04.29. We tried building it from the top of the master branch using
bitbake but it fails to configure. Is there any newer version of this
package that is know to work OK on MCSDK environment?
(I posted this question to TI E2E community. I am asking here too in
case someone can help out. Apologies for the double posting)
