VCHIQ doesn't work on ARM64

Open mariobalanica opened this issue 3 years ago • 2 comments

The ACT led starts blinking 8 times in a pattern when the driver is loaded, indicating a VCHI error. It doesn't respond to any commands afterwards (tested using some of the ported userland apps here: https://github.com/ms-iot/userland)

I recall seeing the hello_jpeg sample work on ARM32 (RPi 3), but subsequent runs resulted in either the driver hanging or a bug check.

The VCHIQ initialization issue with blinking ACT should be resolved with 051a7c89b500fc401f5d7f98dde3ff76959ff0ee, more validation needed.

This device shows up with yellow bang in Windows (installed via WoR) on RPi 400
