Re: [U-Boot-Users] Enabling watchdog for MPC850

Hello,

Please define "crash". Does the board simply reset (like after a watchdog timeout), or is there any error message, or what?

The board simply resets.

Then this is just the normal watchdog reset.

You always have to configure both sides to match, i. e. if you enable the watchdog in U-Boot you must do so in Linux, and if you don;t enable it in U-Boot you must not enable it in Linux (althought in that case you will not crash the system).

How do I enable it in Linux?

Select "CONFIG_WATCHDOG=y" and "CONFIG_WDT_MPC8XX=y".
