Other Parts Discussed in Thread: F28M35H22C

Hello: When I run code from shared memory on the c28 side I am having problems with the DMA transfering data from the A/D to memory. The M3 is not accessing the shared memory. Any body encountered a similar problem or any body has an explanation for it?

Hi Arye,

We are not aware of any issue with C28 DMA standalone access to Shared RAMs. Is it possible for you to provide little more detail on this issue?

Also we have RevA Si available for this device. If possible, I would suggest to run the same code on RevA device and see if it behave same way.

Regards,

Vivek Singh
