AM62A7: Using the WKUP_UART from Linux

Jonathan Cormier

Part Number: AM62A7

Is it possible to disable the WKUP_UART in the dm_edgeai_mcu1_0_release_strip.out firmware so the A53 can use it from Linux?

There is a guide here on how to disable the WKUP_UART for the AM62x

https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/latest/exports/docs/api_guide_am62x/DEVELOP_AND_DEBUG_DMR5.html#autotoc_md358

However, The AM62A version of the MCU SDK, is missing this. https://software-dl.ti.com/mcu-plus-sdk/esd/AM62AX/11_01_00_16/exports/docs/api_guide_am62ax/DEVELOP_AND_DEBUG_DMR5.html#autotoc_md291

Unfortunately, the AM62A uses a special build of the DM firmware to add something for the AI support and so the standard MCU firmware used by the AM62x/P isn't one to one compatible.

I downloaded the mcu_plus_sdk_am62ax_11_01_00_16 just in case, but unfortunately there doesn't appear to be any reference to the following filename anywhere in the provided code.

Hello Jonathan,

Before we proceed, could you confirm whether you are using the VPAC/ISP camera functionality on your AM62A7?

The reason we ask is that dm_edgeai_mcu1_0_release_strip.out is an AM62Ax-specific firmware that includes VPAC/ISP code alongside the DM task. Depending on your answer, we will route this to the appropriate expert for further assistance.

Hi Harshith,

We are not using any cameras in our current project so we do not need that functionality.

Thanks,

Holden
