Hi,i’m an noob of dietpi.My Screen resulotion is 1280*800.I used the screen with rpi3B+,i added
hdmi_timings=1280 0 48 32 80 800 0 3 6 14 0 0 0 60 0 71000000 3
hdmi_cvt=1280 800 60 6 0 0 0
hdmi_group=2
hdmi_mode=87
hdmi_drive=1
in /boot/config.text .It worked well.
Now i using nanopi-r5c,config.txt is missing,i add extraargs=video=HDMI-A-1:1280x800@60 drm.edid_firmware=edid/1280x800.bin in /boot/DietpiEnv.txt,it not work .
EDID file export by moninfo.
Why not using dietpi-config?
Sorry to ask off topic @DDknightLEI but I just saw we’re both noobs, we both have r5c, and you are ahead of me.
My r5c won’t even boot to the sd card, it just boots straight into the default FriendlyWRT.
How did you get it to boot from the sd card? I followed DietPi flashing instructions.
Is there something else to do?
(My post is at Nanopi R5C seems to ignore SD Card in boot order )
@nzchip pls don’t highjack this topic and stay with yours. thx
@JappeYep, i tried this, dietpi-config not support display option with rc5 or r5c (nanopi) because it is builded of armbian,not the classic rpi linux system
