I was able to connect to the chip via SWD/openocd, but I can't figure out what chip it is (says SM9PQ1 2322-52 on chip, googled but cant find anything). I'm hoping to download the firmware after I connect to the chip using the correct config file for openocd. Is there any way I can find out what chip it is? The chip does video compression by the way.
