Watchdog usage on MPC5200B platform

Watchdog usage on MPC5200B platform

[Juergen Beisert]

Hi,

has anybody an idea why when I'm using drivers/watchdog/mpc5200_wdt.c, the=
=20
system freezes instead of doing a restart?

When I'm running the "reboot" command it does a restart as expected.

=46or both cases the same hardware will be used (WDT in timer@600 marked=20
with "fsl,has-wdt" in the oftree).

Regards
Juergen

Once again: It does a restart with kernel 2.6.23, but not with 2.6.26. Agai=

it seems something related is not setup correctly. Any idea? I didn't find=

anything special in the MPC5200B generic part of 2.6.23.
