Question about fdOpen().

Doug,

Where/how are you creating your Task?

The likely cause is that the stack has not come up yet (i.e. your Task is running too soon, prior to the NDK boot up).

A good place to create your task is from the "network IP address hook" function. This is because (initially) when the IP address is added, it means the stack is up. However, you must be careful if the NDK is rebooted, because that hook would run again and re-create the same task (also if an IP address were added again).

So, you need to add code to ensure the Task is only created the number of times that you want.

Please refer to this related post:

Note that you could also pend on a semaphore within your MainTask, and then post it within the IP address hook to unblock MainTask once the IP address has been obtained:

The tasks are created statically via the GUI in the *.cfg file so they are only crated one time. I also run a static IP address so I am not using DHCP. After reading about this and some other forum posts, it looks like I need to add a hook function that will release a semaphore like in this example:

e2e.ti.com/.../6431.hooks.png

Is the "network IP address hook" the hook highlighted in the above link?

Thanks,

Doug

Doug,

No, but close. It's the one all the way on the bottom right, under the category "Network Callback Hooks"
