TMS320DM8168: How to Access ARM processor shared memory from VoLIB

M Syd Ahmed

Hi,

We are working on DM8168 Board. We are using EZSDK based Linux Kernel for controlling ARM processor. While, we needs to use VoLIB lbrary in DSP. Now, we needs VoLIB library to access shared memory created by ARM processor. How to access ARM processor's shared memory through VoLIB library?

Hi Margarita,
We were able to communicate between DSP and ARM using Syslink. But our requirement is DSP in which VoLIB library is running should access shared memory with ARM. My question is how did VoLIB library access Shared Memory?
