Hi there,

There are LMU controllers and DAM controllers on TC275. But DAM is not in the memory map. What is the relationship or difference between LMU and DAM. I am initializing DAM using the sample code in AP32197 but the LMU got Zero'ed.  A little bit confused.

Thanks,

Ke

Hi Ke.  DAM is an accelerator with a very small RAM buffer (0xF8700900-0xF8700BFF) that can read and write to LMU RAM (0x90000000-0x90007FFF).  For the TC27x, the MTU DAM instance (79) refers to both DAM RAM and LMU RAM.
