How to check contents in Cmem allocated buffer from gdb?

We are debuging some issue on DM385. Using gdb, when I tried to print contents in a cmem allocated buffer, gdb always claims memory can not be accessed. Is there any we we can examing such buffers in gdb?

Also, in ARM-only build, is there anyway to make CE to allocate memory for algorithms using regular memory instead of cmem?

Thanks,
