Description Yi Zhao 2024-12-23 06:05:56 UTC 
Image Location: https://valkyrie.yocto.io/pub/releases/yocto-5.2_M1.rc2/machines/beaglebone-yocto/

Git rev: master/fafd1db382cc24c53c17170df82780f9d593ca1f

Steps:
1. Download beaglebone core-image-sato-sdk wic image from the above link.
2. Deploy wic image to MircoSD card and boot up system.

The matchbox-desktop fails to start, leaving only a black screen. But I can connect the system via serial port.

The X server process is running but there is an error in Xorg.log:

Comment 5 Randy MacLeod 2025-01-09 15:40:54 UTC 
If we can test this and prove that we have a fix in master, then we can release M1. 

Kevin, Yi, what's the plan?
Comment 6 Kevin Hao 2025-01-10 02:00:16 UTC 
The kernel fix has already been merged into linux-yocto, but it is not yet included in the SRCREV_machine in the oe-core recipe. I have just sent out a patch [1] to set a machine specific SRCREV_machine for beaglebone to pull in this fix.

Comment 7 Kevin Hao 2025-01-14 13:01:34 UTC 
Bruce has updated the kernel to v6.12.9, which includes the fix for this issue.
Comment 8 Denys Dmytriyenko 2025-01-15 20:03:36 UTC 
FWIW, I built my own Sato images from latest Poky/master and can confirm that this issue is now resolved - X starts fine on BBB and displays Sato desktop.

Verified with 5.2 M2 RC1. Git rev: 59db27de565fb33f9e4326e76ebd6fa3935557b9
