AM5708: Questions about Dev Id and ENDIAN used to create SD card programs

Hi,

You can refer to RTOS documentation in the links below:

1)  https://software-dl.ti.com/processor-sdk-rtos/esd/AM57X/latest/exports/docs/rtos/index_board.html?highlight=multicoreimagegen#creating-the-sd-card-loadable-files

This command looks fine, except for A15_0 core Id should be 3 and not 0.

Thank you for your answer.

I wonder why the core ID of Cortex A15_0 should be 3.

Is it in the manual?

I am not able to find the relevant document, but generally you can always get the core id by launching the respective target configuration in CCS and manually counting starting from zero.

But what is your use case here? I just noticed that you are using AM5708, but I don't think RTOS SBL support is available for AM570x.

I am using RTOS on AM5708.

The AM571x and AM570x Sitara Processor Technical Reference Manual (Rev. J) describes eMMC and SD Booting as follows:

page : 7544/7686

If you look at the flow chart above, I think it will be possible to boot through the SD card.
In the case of AM570x series, is RTOS impossible to boot through SD card? If not, I wonder why.

You made a good point at the heart of the matter.
Your answer was very helpful to me. !
I have no further questions.
Thank you for your help.
