Is there a watchdog config in Fiasco or L4re I’m not aware of? Or it is due to how I load the uimage? > > I loaded the bootstrap_hello.uimage as this: > # U-Boot SPL 2014.04-00014-g47880f5 (Apr 22 2014 - 13:23:54) It looks like the TI am335x has a watchdog, which is enabled by uboot (at least here in include/configs/ti_am335x_common.h, uboot 2016.11). So it looks like uboot leaves the watchdog in an enabled state and expects the booted system to handle the watchdog. You could try to disable the watchdog in uboot or try to enable the watchdog driver in l4linux (or add code to pkg/bootstrap to disable the watchdog before starting fiasco, or write a small watchdog server on top of l4, ...) ... regards, Jean _______________________________________________ l4-hackers mailing list [email protected] http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers
