Migrating ZynthianOS to 64 bits

Well my Pi4 desktop has now successfully updated and upgraded to bullseye @ 64 bit…
Reasonably painless, but took a while . . .


yeah. Nice how the naming scheme in sources.list changed this:

deb http://security.debian.org/debian-security/ bullseye/updates main
deb-src http://security.debian.org/debian-security/ bullseye/updates main

Is now this:

deb http://security.debian.org/debian-security/ bullseye-security main
deb-src http://security.debian.org/debian-security/ bullseye-security main

Just built a 64 bit Pi os as a clean machine on a Pi4

It’s considerably more usable than it was and a lot slicker ( so far)

No loner required to pick up a USB imager. It Uses’ Pi imager which recognises 256G ssD’s which USBIMager didn’t seem to.

Hopefully screen grabs will be a fair bit less hit or miss as they were before and I’ll hope it’s addressed some of the keyboard and window lag.
google also seem a bit more trusting of the whole infrastructure.

I can now put my previous 256G SSD into the backup draw.

Also running it on a Pi 3 so we shall see…


Pi 3 & 64 bit seems a bit crappy.

bcm2835-codec bcm2835-codec: bcm2835_codec_buf_prepare data will not fit into plane (1536 < 353280)

which kills the Pi HDMI graphics dead.
Can still log on from remote machine.
Anyone know how to restart a PI in this state without init 0’ing the poor beast?
It does seem to come back to life after a bit or not.

Getting to be irritating…

Is this problem on a Pi4 or Pi3? My Pi4 (8GB) has 64-bit and it runs fine.
