I've now found this info in the reference manual - not under the watchdog section but elsewhere - under the boot modes. So now I can concentrate on why the zbarebox.bin wont run!

When the i.MX25 boots using the serial protocol boot mode (either UART or USB) the watchdog gets enabled automatically. You can't disable it. baruch -- http://baruch.siach.name/blog/ ~. .~ Tk Open Systems =}------------------------------------------------ooO--U--Ooo------------{= - baruch@tkos.co.il - tel: +972.2.679.5364, http://www.tkos.co.il - _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
