Not able to see any output if kernel module loaded for the first time

[Vijay Nikam]

Hello All,

I am facing perhaps some strange kind of problem. I have mpc8313erdb
eval board and wrote the GPIO driver, the driver is just making the
assigned GPIO[3] pin high and low.

If I load this module first time after bootup or if I make some change
in the code and compile and load the module, then I am not able to see
any output on the scope but if I load it again then I will be able to
see the output on the scopt that GPIO[3] pin has became high and low.
Later if I removed the kernel module and load it again then also I am
able to see the output on the scope, till I do the reboot or power-off
and on.

Could anyone let me know why this happening ... thanks ...

Kindly please acknowledge ... thank you ...

Kind Regards,
Vijay Nikam
