Other Parts Discussed in Thread: CCSTUDIO
Hi,
a. I'm working with DM8148, I'm trying to configure Mcbsp from dsp, but now I'm seeing a strange phenomenon:
All of the mcbsp memory map (starting from 0x47000000) is 0, including read only (such as REVNB register).
Trying to write to registers in the memory map doesn't succeed, all values remain 0.
What can cause this? How can this be solved?
b. Trying to configure the Mcbsp from the arm, I run ProcMgr_map to map 0x47000000 master phys to master virt, it's successful, but when I check the translation, the 0x47000000 physical address is translated to a different master virtual address. When trying to read the master virtual address, the arm process terminates.
My questions are as in (a): what can cause this? How can this be solved?
Thanks,
Gilad
