AWR2944P: Debugging RF Sensor Startup Problem on D-Version Chip

Part Number: AWR2944P

Tool/software:

When MSS executes MMWave_init() or MMWave_start(), the system may hang at the Mailbox_waitWriteAckIntr() function in mailbox.c.
- The hang is caused by isAck remaining 0, meaning that the ACK signal is never received from the other core, leading to a deadlock.
The above problem only occurs in AWR2E44P D-version chip, and does not occur in AWR2E44P G-version chip.

Hi Jack,

Can you confirm if you are using any of the HSM services in your application?

May I ask what aspects of the HSM service you are referring to? My current APP only calls MMWave_init(), and if successful, it prints Hello World!!

Hi Jack,

From the HSM services, I meant if you are configuring the hsmclient anywhere in your demo syscfg?

sharing a snippet here for your reference:

please check and let me know if you have enabled this option in your demo.

Also, can you confirm if you are using any of the default demo for your test, or it's your custom application?

Regards,

Shruti

The setting of HSMCLIENT in syscfg is exactly the same as the picture you attached, but I don't use any functions related to HSMCLIENT. Will this have any impact?

Hi Jack,

If you are not using any of the HSM services, then you can disable this HSMCLIENT configuration in your syscfg gui. Let me know if this resolves your issue.

Yes, if I turn off HSMCLIENT, it will not get stuck. 
However, the same method will still get stuck in the project we are developing. 
Please tell me where else this problem could be caused. Please tell me what to try. Thanks!
