In case my experience is useful to anyone else, it seems this is what was happening: - RBL was enabling Timer0 and its FIQ - perhaps to flash an LED warning that I have no valid UBL on my NAND - My JTAG connector lacks SRST so the board was not getting fully reset - u-boot was loaded and run over JTAG (ignoring Timer0 + FIQ?) - Linux starts, enables FIQ in boot_cpu_init() and crashes because it has not setup the interrupt vector tables yet. I added a software disable and clear of interrupts over JTAG to my "reset" handler, and now I can boot. -- Jon Povey [email protected] Racelogic is a limited company registered in England.
