Thanks for verifying this, Fabio. The mx28 generates timer interrupt after it should be sitting in the endless loop, therefore this crash. I think it's because the mx28 (mxs at al) is using the new clock framework (compared to mxc) and the timer isn't deinited by then ... Disabling interrupts might be just the right solution, though I'm not sure if it's not hiding bugs ... > Regards, > > Fabio Estevam Best regards, Marek Vasut
