video not properly initialized after warm reboot

[pilou75]

I don't know where the issue is. Recalbox or PINN.

When recalbox is used, and restarted, there is no display at PINN boot selection menu.

At first, I thought it was hanged. It's not, it's just a blank screen, otherwise looks OK.
I tried also with new install, and it's same. If recalbox 8.1.1 is used, no issue, but as soon as it has been upgraded to 9.1, blank screen.
Others distro I use, have no issue (raspbian, libreelec, batocera)

No idea either.
Sounds like something is not being totally reset on a soft reset. Probably something for RPL engineers to advise on 😉

Are you using a Pi5? If so, try commenting out the dtoverlay=vc4-kms-v3d line in config.txt of PINN to see if it makes a difference. 🤷‍♂️

I forgot to mention. It's a PI4B

well, I updated Libreelec from 10 to 12, and now, I don't have any display when (warm) reboot
somebody else have similar issue ?

I have similar issue when I updated firmware on raspberry with pinn in Libreelec 10, sudenly I have "black" screen when booting LibreElec 9.2.8
For me help copy of file start.elf and fixup.dat from booting partition of LE10 to booting partition LE9.2.8

Maybe it is also something with firmware.

Does the same problem occur with a direct Raspberry PI OS install and soft reboot (i.e. without PINN) or even with PINN?
Or with a direct install of LibreElec 12 and soft reboot?

Short answer, does the same problem occur with RaspberryOS no, does the same problem occur with LibreElec yes

Here is all tests I did today :

LibreELEC 12 without PINN : the rainbow screen appears shortly during reboot = looks good to me
LibreELEC 12 with PINN : "blind" screen after reboot, I mean no rainbow, no press-shift picture, no boot selection menu, nothing until KODI starts

RaspiOS is always fine (rainbow screen appears shortly), with or without PINN

I have several things attached to the PI4 : USB Keyboard, USB PS3 Controller, and Hifiberry digi.
I tried to remove them, one by one, no improvement.

I would to try using another display (LG TV), but I have nothing else at the moment.

I tried with recalbox : 8.1.1 (PINN) is OK, but after upgrade to 9.1 have the issue.
I put back bcm2711-rpi-4-b.dtb, start.elf, and fixup.dat from 8.1.1. It doesn't help.
