Hello,
I would like to know if it is possible to access the peripherals directly from the PL without running any software on the PS. Would it be this the use of an AXI Slave? if so is there any IP open IP to control the communications with these peripherals?
The reason of asking this is to be able to do one of these things:
- Read a video input wired to the PL, perform some transformation and output the resulting image to the DP.
- Do a raw reading directly from the SD port available on the ultra96.
- Communicate with the PL using the onboard UART on the Ultra96.
- Use the Ethernet peripheral, generate some traffic from the PL and output the result to a PL IO pin.
I could even use a soft core cpu to implement the drivers but I would like to know till which extension the PS can be ignored and the PL can control elements from the MpSoC
