RTOS/CC3200: AWS IoT subscribe_publish_sample hangs on sl_Start

Part Number: CC3200

Tool/software: TI-RTOS

Hello,

I am trying to run subscribe_publish_sample from AWS IoT samples on CC3200. I am using v2.1.0-ti branch from git.ti.com/iotdev/aws-iot-device-sdk-embedded-c.git. I was able to compile and setup the sample. I was able to run certflasher.out application but the problem is running the subscribe_publish_sample itself. It constantly hangs on _SlDrvRxHdrRead function when sl_Start is called. Whatever I do (restart application, reset chip, power off/on launchpad, etc.) the app ends up in the same function and stays there forever.

I was trying to flash the example application using uniflsh to device, but it does not start at all (maybe something with wrong adresses in the sample, but I did not dig into it).

Can you point me what can I do to run this example?

Regards,

Piotr M.

Hi Piotr,

Do you have the latest service pack? It can be downloaded here:
www.ti.com/.../CC3200SDK

If updating the servicepack to the latest doesn't work, try applying this fix:
e2e.ti.com/.../2083679

Let me know if those debug steps don't work.

Regards,
Michael

Hello Michael,

I have uploaded service pack to the device using UniFlash. I have applied fix and recompiled TI-RTOS. Still the same result. The only difference is that now I can see source code and lines when it hangs. I checked two devices, result is the same in both cases. What is weird, I run into this trouble in certflasher.out app but resetting lounchpad helped. In case of subscribe_publish_sample I constantly have the same result.

Hi Piotr,

I am not sure if this is not related to your issue ( e2e.ti.com/.../1806610 ). Please check it.

BTW ... what version of LaunchPad do you use?

Hello Jan,

Unfortunately, it hangs in different place:
driver.c : 1458 - VERIFY_PROTOCOL(SyncCnt < SL_SYNC_SCAN_THRESHOLD);

Hi Piotr,

How did you rebuild TIRTOS with the fix applied? In order to ensure that the fix was applied successfully to your project, I suggest that you take a look at the step-by-step instructions in this post and see if that resolves your issue:

I did try the "HWREG(0x400F7094) = 1;" solution but with no results. I end up with porting AWS SKD to CC3200 by myself and I was able to run it with FreeRTOS.

Thank you,

Piotr M.
