That is what the watchdog code does - It is a horrible hack, and every now and again, another patch comes through which adds another call to the watchdog trigger in some obscure loop in some obscure code location. Or someone submits new code for a board that does not have a watchdog that somebody else then uses on a board that does have one and the watchdog suddenly triggers resetting the board. It's messy and ugly. My biggest point about the 'dropped character' issue is that the fix is simple provided the 'tasks' that use the serial console behave and inform the serial console driver that they have finished receiving characters - not a big ask in my opinion. Way smaller that spattering 'Check the serial port' all over the code Regards, Graeme _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
