But in this case, I am not sure it might help - what we need to add is "boot reason" information probably. It does look to me that a reset took place (u-boot hooks up it's own handlers for irq,fiq,abort etc, but they were'nt triggered) - so either kernel abort took place and a wdt trigger caused x-loader to come up in some unexpected configuration that it could'nt handle OR a reset of somesort took place. -- Regards, Nishanth Menon
