I am having a problem enabling the watchdog in u-boot. It causing the Linux load to crash.
Most probably Linux is not crashing but just reset by the watchdog.
Do I have to enable watchdog support in u-boot for the mpc_8xx driver to run?
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).
If so what can I about the Linux crashes?
Please define "crash". Does the board simply reset (like after a watchdog timeout), or is there any error message, or what?
