OMAPL138B-EP: Shared Memory Issue

Part Number: OMAPL138B-EP

Hi,

I am using OMAPL138 processor in one of the projects. In our appliaction we are trying to write data to "shared RAM" (0x8000 0000 - 0x8001 FFFF), and read it back from ARM. 

When I see the memory window on CCS what ever data written is reflecting on Memory window but unable to read same data through ARM applicaion. I tried to read the data written by DSP using devmem2 and also through an application which uses mmap. 

I also have a strange observation, when I manually write somedata through memory window of CCS, and read that through ARM using devmem2 every time data read from ARM is proper. I am quite ununderstandable towards this.

I am using TI RTOS on DSP side and Linux with SDK version 06_00_00_07. 

Thanks,

Janardan M
