Tool/software: Linux
I was trying to upgrade our AM3352 based system from TI SDK 7.0 to the new processor SDK.
I tried the latest SDK 3.0, but was having problems with the new systemd. The system will run extremely slow.
I went back to ti-processor-sdk-linux-rt-am335x-evm-02.00.02.11, which seems to work OK on the Beaglebone Green board.
However, when I tried to port the SDK to our custom board, I got some error messages from the PRUSS.
