MCU-PLUS-SDK-AM263PX: AM263Px: SemaphoreP_pend Hang in Custom PMIC Flow

Abdul Mohasin Shaik

Tool/software:

Hi Team,

I am currently using the AM263PX evaluation board. While testing CAN communication, the flow is getting blocked during PMIC configuration — specifically at the following lines:

to enable Pinmux Mode I have added lib files from the SDK provided by TI, and I got this issue where I have added these lib files in my demo. Interestingly, when I test the same SDK, everything works correctly — the semaphore for CAN Tx completes successfully:

This suggests the issue is not with the CAN peripheral or semaphore system, but possibly with PMIC SPI or MCSPI configuration.

Could you please guide me on what might be going wrong and where I should investigate further?

Thanks & Regards,

Hi Shaik,

What does your PMIC configuration do? Does it change the power supplies and reset the device?

Hello Wang,

We are not using any pmic configuration, we have taken it from the sdk "mcu_plus_sdk_am263px_09_02_00_56" and we have taken library/object files from examples :\mcu_plus_sdk_am263px_09_02_00_56\examples\drivers\mcan\mcan_external_read_write\am263px-cc\r5fss0-0_nortos. Attached the library files in the comment.

Hi Shaik,

The latest the SDK is 10.02.00.15 which fixed some known issues and added some new features. Have you tried the example from the new SDK?

I will do a check of MCAN example from the new SDK.

I run MCAN TX test several times, didn't see any PMIC config issue. The PMIC is initialized and configured correctly during driver open stage.
