AM2612: Am2612 reboot issue.

Part Number: AM2612
Other Parts Discussed in Thread: MCU-PLUS-SDK-AM261X,

I recently upgraded to the new AM261 SDK. Here are the versions I have installed:

- MCU-PLUS-SDK-AM261X Version: 11.00.00.29

- INDUSTRIAL-COMMUNICATIONS-SDK-AM261X Version: 2025.00.00.08

After a certain period the AM2612 is getting rebooted.

I tried adding the SOC_getWarmResetCause() function at the beginning of the application code to identify the cause of the reboot. However, it consistently returns 0x41, which indicates a Power-On Reset.

Could you please provide guidance on how to debug this issue further?

Thanks in advance for your assistance.

Hi Vivek,

1. Which boot mode are you using?

2. Are you using a ti evm or a custom board?

Hi Nilabh,

I’m currently running the firmware from FLASH using OSPI boot mode on a custom board.

Hi Vivek,

I think it is happening due to PMIC IC, can you try following workaround:

In your SBL OSPI MCELF project, enable/add PMIC in the syscfg, then rebuild the example and flash it.

Hi Nilabh,

I’ve added the PMIC to the sbl_ospi_multicore_elf project, which I was using as my bootloader. However, after flashing the sbl_ospi_multicore_elf from this project, the application firmware fails to load.

Please find attached the PMIC and I2C configuration.

Can you share the UART logs when the SBL is running and also during application fail, that will help me debug further.

Also Is this an TI EVM or custom PCB ?

I don’t see any SBL logs when I add PMIC. However, if I run my current SBL without PMIC

Can you answer if this is a behaviour you are seeing on TI EVM or your custom PCB?

custom PCB

Vivek, lets have a call to debug this, It is difficult for me to understand the issue from the info shared

Issue was resolved after adding the PMIC configuration in the SBL syscfg.
