[opensuse-arm] Joy-Pi 7" Pi Screen No Signal
Hi all, The openSUSE Project now has a Joy Pi to show at some of the conferences. However, I tried the latest TW RP3 image and after the bootscreen, the screen phases out to a no signal. It's this screen here: https://www.joy-it.net/en/products/RB-LCD-7-2 Do any you have any documentation or recommendations on how I can try to fix these during the boot. I'll do some research as well, but I thought I would ask you all first, since you might know. v/r Doug -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

That's great! 😊

This is an HDMI display, right? The documentation suggests to try the following options in Config.txt: dtparam=audio=on max_usb_current=1 hdmi_force_hotplug=1 config_hdmi_boost=7 hdmi_group=2 hdmi_mode=1 hdmi_mode=87 hdmi_drive=1 display_rotate=0 hdmi_cvt 1024 600 60 6 0 0 0 Could you try them, please? But the firmware seems to handle the LCD display properly as you have the boot screen (up to Grub?). So, my guess is that the Linux kernel try to reconfigure the display and fails. Do you have some kernel traces to share?
Do any you have any documentation or recommendations on how I can try to fix these during the boot. I'll do some research as well, but I thought I would ask you all first, since you might know.
As stated above, my guess is the Linux kernel fails to set a proper resolution. Cheers, Guillaume

Thank you Guillaume. I tried to figure it out, but couldn't figure out the documentation for the config.txt. I plugged it into a different screen and then plugged it back into the 7" screen and now it works. Not sure why it would do that from the first boot and then work, but next time we see each other, I can show you the device. v/r Doug On 10/28/19 8:25 AM, Guillaume Gardet wrote:

Thank you Guillaume. I tried to figure it out, but couldn't figure out the documentation for the config.txt. I plugged it into a different screen and then plugged it back into the 7" screen and now it works. Not sure why it would do
So, IIUC, it works without the config.txt quirks, right?

Yes, I can have a look. Cheers, Guillaume
