Hi folks,
I have installed a current release image on my OLINUXINO MICRO (Rev G): A20-OLinuXino-buster-base-20201105-143953.img
I have also a OLIMEX Display attached to it, which works just fine using an older image with 3.4.103 Kernel.
Because the newer image relies on the EEPROM configuration, I have configured the EEPROM like this:
U-Boot SPL 2020.04+olimex-2-20201004.114205 (Jan 30 2020 - 11:10:18 +0000)
DRAM: 1024 MiB
CPU: 912000000Hz, AXI/AHB/APB: 3/2/2
Loading configuration from EEPROM: OK
Verifying data: OK
Trying to boot from MMC1
U-Boot 2020.04+olimex-2-20201004.114205 (Jan 30 2020 - 11:10:18 +0000) Allwinner Technology
CPU: Allwinner A20 (SUN7I)
ID: A20-OLinuXino-MICRO-n4GB Rev.G
SN: 00001234
MAC: A0:F3:C1:71:7D:89
I2C: ready
DRAM: 1 GiB
MMC: mmc@1c0f000: 0, mmc@1c12000: 1
Loading Environment from EXT4... OK
...
then I have configured the output to "LCD-OlinuXino-7" hit ok and reboot:

Then video output came on the LCD, everything looked fine untill the Xorg comes up:

I'm confused, because the same hardware hasn't any problems with the older image.
Is there any possibility to tune this right?
I tried xvidtune, but I can't change anything without getting an popup telling me the hardware doesn't support the setting.
Any ideas what i can do?
with best Regards,
Peter
Interesting. I found one board like that (A20-OLinuXino-MICRO-n4GB) here and 7 inch display and tested with same software configurations and no such issue exists.
Maybe try slightly different configurations in both the olinuxino config setting in u-boot and the olinuxino-display script (for example, check if it works better if you set it to 7 inch TS display)?
Maybe the cable or its connectors got wonky?
Try to re-write the image and re-configure it, in some corner case scenarios it might get corrupted in a funny way.
