Re: AT91 bootloader/u-boot to enable the watchdog timer
Here's the last file (for those with 128MB of RAM). Please take care using these files. You will need to upgrade u-boot first. This upgrade the AT91 bootstrapper. By default, uboot will disable the watchdog timer. To enable it, you need to do this:
setenv watchdog on
saveenv
You'll then need to reset your board. The CPU, once you've modified watchdog parameters, will not allow further modifications until the CPU is reset.
