Raspberry Pi 4

My version should not make any difference since it just adds support for the 7C80 and 7C81. I have merged my changes to Berthos new code ( my previous version was using svantegs patch). I have not tested it yet but will try tomorrow.

I was using a 2.9.0pre , run in place. btu it also looked like i had a 2.8pre run in place, which also didnt load for the same reason. im reloading the image from scratch now so ill see hopw that goes. this is my start up from 2.9

Do you use my version with a new card? This message looks like it:
hm2_rpspi: Unknown board at SPI0/CE0: MESA7C81
I have not incorporated PCW's changes to support additional boards. That said, the driver loads and communicates up to the point where it detects an unsupported board.

So, if you are using my new driver, then at least it would be confirmed that it can talk to the RPi hardware.

I've hit a show stopper here. For some reason /media/pi/workspace, a 240GB ssd plugged into a usb3 hub, plugged into a usb3 port, went ro while sitting hot overnight. And now I can't boot a fully functioning rt kernel, its screen is 16 pixels small all the way around, and while the ssd's must be mounting as there's 3 disk icons on this undersized screen, but no mouse or keyboard response. Edit /boot/config.txt to restore the default non-rt boot, and it all works. I'm plumb bumfuzzled, been around this loop about 8 times now and need to fix some lunch for us.

Do you have a heatsink on your rpi 4b? I have been reading about them running hot and causing some people problems.
