Hi, I want to enable the hw watchdog (on my i.mx51 board) early in the boot process - ideally before the ethernet controller is initialized. Has anyone written a redboot extension for this yet?
If not, I might do it, but I don't want to duplicate efforts ;)
I've recently added a section about enabling the watchdog on SBC-i.MX51, see here: https://support.bluetechnix.at/wiki/SBC-i.MX51_Software_User_Manual#Watchdog
It enables the watchdog in Redboot in the boot script, before loading the kernel. Generally, you may enable it at any time I guess, because Redboot services the watchdog as long as it is "active".
