@numbqq @Frank @Gouwa any ideas? Thank you!

Just checked my local build image for VIM3L, the LCD works fine.

Can you see the u-boot logo display? Have you do some modifications ?

I have managed to make it work in VIM3L by disabling and enabling the /sys/class/lcd device… also made it work in EdgeV … but now it does not turn on… after rebooting with no changes to code nor OS. is it normal to not have the D1 soldered? Please see the attached image

Please I need this to work urgently

Yes, it is.

I’m a little confused. Once you said VIM3L, and then Edge-V. How you get VIM3L to work? And which board stop to work, does it works before?

9

The flex came broken, so when I moved the lcd board it got on/off:

How can I claim this?

10

I got the VIM3L working by disabling and enabling the /sys/class/lcd device… this is a bug and it does not happen in EdgeV

11

I don’t need this operation, I will push latest code in this month.

Hi quatro
please help to check

13

point 1, pins 39 to 36, exactly in the joint between the pads and the tracks

14

can you please add DRM/KMS support to VIM3L as EdgeV has? my application needs this, and also I’m looking forward to have the app being cross platform between Edge and VIM platforms
