I know. In fact, I already have such a rpi debug probe [1] at my desk. Nevertheless, haven’t tried to fire up the rpi5 with your u-boot.bin to see if anything sensible comes up at that special UART debug port which could explain the stalling and no HDMI output I saw here last time I checked. > Let me update my Tumbleweed image and check again. Thx. Can you perhaps also elaborate on your build environment for that particular u-boot.bin build? Or perhaps put a binary of it somewhere so that I could check if it works with your u-boot.bin build. > Just to reiterate that if not properly syncing > content to uSD card could have strange side effects. I am aware of these kind of issues. But in fact, I am quite sure I synced all content properly to the microSD card.
