BSC9131 read memory on both sides

Hello,

I want to read memory cells (some equlaizer wieghts) on the e500 linux side that are in use on the DSP SC3850 side for online debug (see the wieghts value on screen) without using IPC.

The DSP is writing the wieghts to specific address in the DDR, but when i try to read them with cpp app i wrote on linux (e500) i get "segmentation fault" error.

Is there a way to somehow overcome this?
