Problem in setting timeout from user space for MPC 83x watchdog timer

[Aswathi C]

I am using MPC 8323E processor and linux-2.6.24 kernel.
I tried to set watchdog timer from user space using ioctl with the case
WDIOC_SETTIMEOUT.
I am getting timeout value as seconds and calculating corresponding modulus
for the WDT.
After that I am setting SWTC of SWCRR and writing service sequence to SWSRR.

But SWCNR is setting back to 0x after service sequence written into
SWSRR, means it is not setting with configured SWTC.

Can anyone tell what is the problem?
Please suggest solution..

Can user set timeout for MPC 83x watchdog timer

Hi Kumar,

I would like to know whether user can set timeout from user space for the
watchdog.
I am using MPC 8323E processor and linux-2.6.24 kernel.
If user can set, can you tell me how will it be implemented?
