OSA_TimeDelay() returns immediately in i2c_rtos_mqx_frdmk64f demo but works fine in i2c_comm_mstr_frdmk64f demo

[yorknh]

Pretty much as the title describes, OSA_TimeDelay doesn't appear to work in the i2c rtos demo. It doesn't hang like someone else had noticed in one of the k64 tower demos, instead it returns immediately. When I run the i2c comm demo instead, OSA_TimeDelay works fine.

Can anyone give me some guidance as to where I should look?

This is using KSDK 1.1.0 with KDS2.0

Hi Larry,

I test both demos and they work without some problems.

I have focused on i2c_rtos_mqx_frdmk64f and make some modifications with OSA_TimeDelay() and made screenshot for you.

When I set OSA_TimeDelay(200) in task_master(task_param_t param)

I got the correct output

When I set OSA_TimeDelay(300) I also get correct output

Best Regards,

Ok I will attempt what you did. In the meantime, can you explain the errors the debugger was displaying?

Thanks

Larry,

I try to solve it, but what do you exactly do for the modifications in your project?

Iva,

I just reinstalled KSDK because I had inadvertently modified some of the demo src files prior to making a copy of the originals. With a fresh reinstall it seems to be working fine.

If I happen to run into the problem again, I will make note of what change triggers it. That said the debugger error messages should give a clue about what is not right, if they don't,

then what's the point in displaying them?

Thanks,

Larry

Hi Larry,

Ok. If the problems still persists, can you upload the project ?

The errors could related with that GDB debugger is not able to read the value for that variable.

Hello Larry,

I will check it on my side and tell you.

Iva,

I've narrowed it down some, though I don't really know what to make of it. There appears to be something wrong with the td_ptr. I've stepped through the _mqx function and the debugger display errors associated with the TIMEOUT structure within td_ptr. I've attached a screenshot.

When _time_delay gets called, the TIMEOUT displays the same errors so it is hard to know what is happening.
