AM623: Issue Flashing SBL and Debugging DM R5 on Custom Board

Part Number: AM623
Other Parts Discussed in Thread: UNIFLASH

Tool/software:

Hi TI Team,

I am currently developing applications on the Device Manager (DM) R5 core using the MCU+ SDK. While I am able to successfully debug and flash the application on the EVM, I am facing challenges with the same process on a custom board. Specifically, I am unable to flash the SBL and debug the DM R5 core.

Documentation Reference: https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/latest/exports/docs/api_guide_am62x/DEVELOP_AND_DEBUG_DMR5.html

I need your support to resolve these issues.

Regards,
Vikash

    Can you please share the flashing logs?

    Okay so this was not required for the log, as its just COM port access issue. Lets take a look at the further logs.

    For this I would suggest you reading through this: https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/10_00_00_14/exports/docs/api_guide_am62x/TOOLS_FLASH.html#TOOLS_FLASH_ERROR_MESSAGES

    Let me know if this helps.
