This is one of those days.
All regular things went excellent, which is the main thing anyway.
All technical things went and are going terribly.
From copying files, to downloading new and needed iso's, to starting appimages on musl, to window rules for applications: each and every one is a mess. Slackware, Gentoo, Alpine > out of the window, done. Getting really tired with all these hoops and no-go's.
I am at the stage to scorch the various earths, flatten all,…

Ok so the first boss fight of the STM32MP2 bringup (getting the A35s running at full speed with caches) is over.
The second isn't going so hot. I've configured all of the documented SYSCFG and COMBOPHY registers (I think). It's not linking up, is in DState 4 whatever that means, and I'm not seeing any change on the tx/rx lines when i do this.
Which means one of two things. Either the register settings I've done are wrong (possible, I'll double check)...

Making progress! 344 unrouted. Definitely getting tight, I may have to delete a few of the test points or shrink things in a bit, but I think I can pull it off. It's been a while since I've done a high density 4 layer board instead of my more recent usual 10L with ViP.
