Recalbox 8.0 on Pi Zero 2 W: black screen

[Bkg2k]

@charger You're not the only one to use a Raspberry pi zero 2, and if "Recalbox 8 is not working on pi zero 2" was true, we wouldn't have release this version

Unfortunately, the Raspberry pi zero 2 has only 512mb of RAM and we must pay attention to some details:

• Do not use a video output in 1080p. Forcing the 720p in the recalbox-user-config.txt is the best way to keep overall resolution "low"
• Disable the Webmanager (it takes too much ram for now)
• Keep the original recalbox theme
• Keep the number of active system low
• Do not use fullsets

You may also try to change your SD card, as they are often the root cause of several crashes and malfunctions.

@bkg2k

Thanks for reply.

I'll try to force 720p, ok. How can I disable webmanager?

[charger]

ok now seems a way better in 720p and without webmanager...thanks...let's see in advance

[charger]

Just a suggestion: you can setup config file in 720p and without webmanager by default. It can help a lot.

@charger It already on our "todo list"

@bkg2k however I’m experiencing lot of crash, again black screen and freeze, and one time I’ve lost completely sd card integrity. Pi zero 2 version is very very very unstable.

I have similar problems, the game starts and runs, I quit the game and start another one, it starts with 1 FPS, recalbox manager is off, display 720p.

@link281 hope they fix as soon as possible; mine lose even wifi config at every reboot, and screenscrapers do not works very often...thanks again to recalbox crew!

[daz]

@link281 same here must be to do with the memory

[charger]

I’ve to remove everything, even overlays, but no way: on quit games, very ofter black screen appears and need to reboot…very frustrating

[link281]

if rewind and overlay is off it works

Hi @charger and @daz

When the problem occurs could share the file /var/log/messages which can be found in Logs tab of the manager by connecting through SSH?

[daz]

@davidb2111 ok I'll have to look how to SSH I have Friday off so will look then is there anyway of taken the memory card out to view the log on my pc

log files are not stored on disk nor sdcard. The only way to get it is through SSH.

Here is a link to get it to work with WinSCP: https://wiki.recalbox.com/en/tutorials/system/access/network-access-winscp

Hello, I did a little research on the Internet. I then read that you can set the ram for video. and I did that in the config.txt set gpu_mem=128 to gpu_mem=64.
And lo and behold, it works without settings you deactivate. Have tested SNES and repeatedly without black screen or FPS break-ins. Will do more tests the days and then communicate it. Sorry for my bad English. I hope I can help

@link281 thanks i will retry with what you have said over the weekend as mine is being used as a pi hole advert blocker at the min as was sick of it crashing
