SIMPLELINK-MSP432-SDK: View POSIX mutex(binary semaphore) status in ROV

Alvaro Muro

Part Number: SIMPLELINK-MSP432-SDK
Other Parts Discussed in Thread: SYSBIOS

Hi,

My system uses an MSP432P4111 with SDK 3.40.1.02, Code Composer Version: 10.1.0.00010, and TI_RTOS POSIX layer.

I have created a POSIX mutex calling to pthread_mutex_init() function in my application.

I see that the underlying TI_RTOS then creates a binary semaphore (sysbios_Semaphore) calling Semaphore_construct() .

I want to be able to see the status of this mutex during debug. However, when I go to ROV -> Semaphores I do not see this mutex in the list. I have searched in GateMutex too, but I cannot find it.

Is there a way to see the status of the posix mutexes in ROV?

Thanks a lot for your attention,

Álvaro

Hi Alvaro,

I'll need a few days to check on this.

Hi Alvaro,

I'm still waiting on feedback from another team and have pinged them again today. Unfortunately, I'm not sure when I'll hear back from them, but I'll follow up with you on Friday at the latest.

James

Hi Alvaro,

I've received some helpful feedback. To answer your question, yes, a binary semaphore can be observed in ROV.

In CCS, I imported the portable_MSP_EXP432P401R_tirtos_ccs code example from TI Resource Explorer. After connecting my LaunchPad to my PC, I clicked download and debug to program the device and start at main(). Next, I opened the ROV. Here's what's shown.

I set a breakpoint at Line 110 and clicked run. No update in ROV. I put another breakpoint at Line 111 and clicked run. Now, you can see the binary semaphore show up under the Semaphores in ROV. Notice the mode says "binary".

I hope this helps!

Regards,

James

Thanks, I see it now! I must have hade some issue in my test code, because it doesn't show up in it, but I could reproduce your steps in the portable example for the MSP432P4111.

Best regards,

Álvaro
