try using code tags instead of quote tags, it makes it easier to read

Done.

Also opened an issue on Github:

The issue occured on a different machine today (unfortunately this one didn't have serial logging connected). Firmware etc. on that one are still like in the first post (i.e. Raspberry Pi OS 2021-01-11 and the firmware/eeprom/vl805fw that comes with it)

This time it drew some weird pixels on the screen, mostly blue ones, but also some red ones in a seemingly random pattern

And it got stuck again with the latest Raspberry Pi OS release. This time no serial log because there was no serialport connected (home office ...)

Just tried it again with Raspberry Pi OS 2021-05-27 (and also ran rpi-eeprom-update -a to make sure it's using the firmware that comes with the release).

Issue still persists, it took about an hour of reboot loop until it got stuck again.

Re: Latest Pi 4 updates do not support GPU mem = 512

Fri Jul 30, 2021 9:06 pm

Just did apt update ( August 29, 2021) which updated seven items, including an eeprom update. An alert message was displayed stating that the system needed to be rebooted in order for the updates to take effect. When the reboot was done, the Pi went into a closed loop. A power cycle did not clear the loop. Boot is verbose without any apparent errors.
Raspberry PI 4B 8G
OS Buster 64bit
Dual HDMI Monitors
USB boot to SSD
Green light on seady except for an occasional blink
Disk activity light constantly flashing
Monitor screens blank except for blinking cursor in upper left corner

Removed the booting SSD and installed a previously working SD card, got the error "This board requires a later version of software"

Downloaded latest Raspberry PI OS 32bit (5-27-2021 full) image and installed on SD card. Booted card and did standard configuration and updates. SD card would boot and the dual monitors displayed the disktop without an issue.

Reset the GPU memory to the same as the Boot SSD (512) and the SD card did not boot properly. Reset GPU to 128 and the SD card booted properly. Reset GPU memory to 128 in config.txt on the Boot SSD and the Boot SSD booted and the monitors displayed the desktop without an issue. Enabled 64bit operation and the SSD booted and ran properly. Reset the GPU to 256 and the SSD booted and ran properly.

It is apparent that the latest updates to Raspberry PI OS and eeprom no longer support 512 as the GPU memory allocation. I have not attempted to run the graphics programs that I was able to previously so I don't know how they will work with the lower memory.

something's not right here.... or maybe am just "dropped out of warp" to another timeframe....?
"Don't come to me with 'issues' for I don't know how to deal with those
Come to me with 'problems' and I'll help you find solutions"

Some people be like:
"Help me! Am drowning! But dont you dare touch me nor come near me!"

See his nickname ;)

Seriously, I think what time_traveler, err, orignal_traveler described is a different issue, maybe related to changes on how gpu_mem is handled (I dimly remember reading somewhere, that more than 256gb gpu mem is not recommended/supported).

This is an update on my previous post about memory allocation issues after an update. I did an update yesterday that covered several Raspberry Pi OS internals. After that update, I again tried allocating 512M to GPU memory. The Pi 4 64b will now boot with a functioning, visible desktop. However, there are still a few issues with running downloaded videos even with Chrome media edition.

I am a Linux Noob, and wondering why you
3. Write "reboot" into /etc/rc.local

I've recently noticed that rebooting does not seem to be reliable on the Pi4. Sometimes, after issueing the reboot command and after Linux has shutdown, it doesn't come back up and just sits there. After a while (not sure something around 20 seconds), the screen turns off and that's it. Only way to get it out of this is to power-cycle.
My RPI4 1GB Raspbian OS (32-bit) too. Sometimes, if RPI starts SWAP to SD-Card, i want to reboot and then no restart. Only Power-off.
For some time reboot works, now after reboot only Power-off (or screen off) again:

After 30 seconds I press the key ESC and I get the screen

Code: Select all

...
[  OK  ] Stopped target Network (Pre).
         Stopping netfilter persistent configuration...
[  OK  ] Stopped netfilter persistent configuration.
[  **  ] A stop job is running for Make remote CUPS printers available locally (47s / 1min 30s)
After 1min 30s normal reboot.

That's ok for me. I just need reboot, no fast reboot.
