Octo Memory Manager driver (OMM) manages:
- the muxing between 2 OSPI busses and 2 output ports.
There are 4 possible muxing configurations:
- direct mode (no multiplexing): OSPI1 output is on port 1 and OSPI2
output is on port 2
- OSPI1 and OSPI2 are multiplexed over the same output port 1
- swapped mode (no multiplexing), OSPI1 output is on port 2,
OSPI2 output is on port 1
- OSPI1 and OSPI2 are multiplexed over the same output port 2
- the split of the memory area shared between the 2 OSPI instances.
- chip select selection override.
- the time between 2 transactions in multiplexed mode.
- check firewall access.
