AM62A7: Using the script uart_uniflash.py burning, AM62A STARTER KIT EVM board can be burned normally, our board burning failed

Hi,

The `sbl_uart_uniflash` needs DDR to receive and flash the images. Have you already integrated the right DDR configurations in both the `sbl_uart_uniflash` stages?

Regards,

Prashant

Hi,

Thank you for your answer.

The DDR we use is MT53E256M32D1KS-046 AAT:L，Do you have a matching DDR configurations file？Or is there detailed documentation on how to integrate the new DDR？

Looking forward to your reply again.

I am moving the thread to our DDR hardware expert for help here.

Once you have the right DDR configurations, integrated them and if still the flashing fails, I will take over this thread.

Hi All,

Thank you very much for your answer.

I regenerated the DDR configuration and can now successfully burn the code using the uart_uniflash.py script. However, the code cannot start normally, the error screenshot is as follows:

The same code can start normally on EVK, what is the cause of this error?

Hi,

This does not look like SBL NULL. Can you confirm what SBL you are using here?

Hi,

Sorry, this is the configuration file I used

C:\ti\mcu_plus_sdk_am62ax_09_01_00_39\tools\boot\sbl_prebuilt\am62ax-sk\default_sbl_ospi_nand_linux_hs_fs.cfg

the error screenshot is as follows:

Hi,

You are right, I forgot to modify the DDR configuration in 'sbl_ospi_nand_linux_stage1', now the code can be start normal

You're really great. Thank you so much

That's good to know.

I have a small request. Can you please share the DDR configurations for your part that works for you? This will be helpful for the other customers who happen to use the same part.

Hi, 

Of course. Thank you again
