Part Number: AM4376
Tool/software: Linux
Hello.
I want run HSR or PRP funtionality on demo board AM4376-IDK without offload to PRU.
I know that offload to PRU now is not supported for AM4376 (supported only for AM57x). Can I run HSR or PRP linux drivers on AM4376 without offload to PRU? Wiki say that this is possible.
I use demo board AM4376-IDK and ti-processor-sdk-linux-rt-am437x-evm-04.01.00.06.
