Hello,
we have encountered the following behavior on AM5726 processor.
We configure GPMC registers on A15 core.
We map first 256 MBytes of address space to GPMC Chip Select 1.
GPMC registers state:

We try to access the same address space from A15 and DSP cores.
All addresses of this space are accessible from A15 core. We check it looking at CS1 line behavior.
Then we try to access same addresses from DSP core.
And we see that access (read and write) to addresses lower than 0x08020000 from both memory browser and code do not generate any events on the bus. CS 1 line remains inactive.
What might be the issue?
Best regards,
Pavel Azizov
