For a week or so I work with the i.MX53 QSB. In this time I've managed to start up both a Linux Gnome build and Windows Compact 7 on the QSB via uSD. Only today I've failed to start up the Linux builds of the FSL orginal uSD with Ubuntu as well as my own Linux Gnome build.
When I try to start up Linux, the QSB won't give any output to the serial console and won't start the start-up sequence. However, when I try to start up Windows Compact 7, all works fine.
Because I get no serial feedback from the QSB, I think it's safe to assume that the problem is caused by U-boot..? Or is there anything else I should know about the prebootloader that can cause this problem.
Please, can anyone help with finding the problem?
