Hello, my udoo quad suddenly doesn't boot anymore, I've tried to insert a different SD card which works in another udoo quad, but the same error shows. At first I can see the UDOO Logo during boot, then it gets black for a while until stripes start to show up and slowly fill the whole screen to white. I've tried to look for it with the serial connection, but i couldn't identify the cause of the error. Maybe something related to a kernel error? Does someone have an idea what to do? I've included the serial output data during boot and also a second serial output data where I got a null pointer reference shortly after booting (don't know how it got so far). Edit: after seeing a similar thread, I also opened a ticket for technical support.
