Which system do you use? Android, Ubuntu, OOWOW or others?

Fails on multiple versions of Ubuntu 24.04 on VIM3 V15 (see below). Works perfectly on Ubuntu 22.04 & 20.04.

Which version of system do you use? Please provide the version of the system here:

Please describe your issue below:

My VIM3 V15 experiences booting failure exclusively on Ubuntu 24.04 (Stuck on solid white light). This issue is unique to Ubuntu 24.04. Versions 22.04 and 20.04 boot reliably every time.

The failure happens regardless of the installation method (tested with OOWOW, USB Burning Tool, and installing to eMMC from microSD card) and persists even on a custom image built via the Fenix repository (v1.7.6).

The device can usually be forced to boot by using “Key mode” listed on the docs; however, sometimes it takes a few attempts. long-pressing the power button, short-pressing the reset button while power is held, and keeping the power button pressed for an additional ~3 seconds.

Once successfully booted, the system runs flawlessly. Software restarts sometimes work without causing a boot failure but sometimes they do. Uploading the recommended bootloader image (github.com/khadas/khadas-uboot/releases/download/0.16.4/VIM3.uboot-mainline.emmc.aml.img) seems to have no effect.

Any help on this issue would be greatly appreciated,
Thank you in advance.

Hello @JamesB

Could you take a high resolution picture of your board ? We need to check the model of DDR and eMMC.

Hello @JamesB

You can try to revert this commit [1] and rebuild the latest image.

cd /path/to/u-boot
git revert d4b8f1b8955665ac96487d9b16b9e98871b58ac7

A solid white LED can still leave a few layers to isolate. Since the same board boots 20.04 and 22.04, I’d compare the failing and working images’ bootloader and environment, then capture the serial console from power-on through the hang. It’s also worth checking the eMMC boot partitions and trying a cold boot with USB peripherals and any external storage removed; if serial shows the handoff point, that should distinguish power or boot media from the 24.04 kernel or DTB.
