[4.1.0 Unstable] Using 7TFT no HDMI image on TV (but I got sound)

[Defiant]

@substring Well I tried and I don't seem to find a complete answer...
I found this article on PINN. I'm not using it, but can this be "adapted" to use on Recalbox???

@defiant mmmhhhh after reading https://www.raspberrypi.org/forums/viewtopic.php?f=44&t=143286 it seems indeed much more complicated than expected as there is some configuration prepared depending on the screen plugged at boot (regarding the framebuffer definition, as I seem to understand) which makes it nearly impossible to swith it post boot.

I remember that switching to HDMI once booted on the DPI failed. Maybe i should give a try to vcgen commands to first disable the DPI and then switch to HDMI, who knows ... The only solution for now seems indeed to use PINN (which seems to be possible). I sadly don't have much time for now to tinker with this

The only solution I found is https://www.raspberrypi.org/forums/viewtopic.php?f=108&t=150889 which is the same as your post on the PINN readme

Alright, I was just thinking the same.
The PINN answer looks like a solid solution.
I will try it during the weekend and let you know how it went.
Thanks!

@defiant great ! I thought about asking the PINN author what it would take to add Recalbox support ... If your tests are successful, you may just make me do the final step to get in touch with him

@substring I'm sad to report I couldn't get it to work
For some reason after doing everything described in the instructions, Recalbox won't even boot on a fresh install.

@defiant Recalbox won't boot through pinn ?

[Defiant]

@substring It does, BUT when I do this step :

7. Edit "recovery.cmdline" in F:, add to the end of the line " dsi" , dont fortget the space-character, and save

Then it will work properly on HDMI when connected, PINN boots perfectly on HDMI, but then when Recalbox starts, the image is back on the LCD.

Then I do the next steps:

8. Go to F:\ and create a config.txt and add the line "ignore_lcd=1" and save

• when starting, the output will be forced onto hdmi with this command. PINN menu will only be visible on hdmi source now
• this is important, so the dsi display does not blink, while using hdmi

9. Mount sd card back into raspberry pi and start into rasbian.

10.Open terminal and go to /boot/

11. Create file "config.dsi" in /boot/ - this config will be loaded, when hdmi is not connected

• dsi display loads automatically and does not need any commands, so the config.dsi can be empty
• you can add later, what usually would go into config.txt to configure your dsi display

12. Create file "config.hdmi" in /boot/ - this config will be loaded, when hdmi is connected

• add line "ignore_lcd=1" to config.hdmi, this forces to ignore the dsi display

After that, it won't boot.

@defiant ah well ... never used PINN, no time available to test

[Defiant]

Still haven't found a solution for this...
Anyone else has any idea?
I appreciate any help!
