But if I replace u-boot with the link [2] you provided, it will work fine. For reference, I was using v2025.01 plus this series of patches [3]. So it looks like u-boot does something and kernel doesn't? [3] https://lore.kernel.org/u-boot/20250123224844.3104592-1-jonas@xxxxxxxxx/ Thanks, Chukun -- 2.25.1
