AM2432: AM2432 UART download failed, show [STATUS] ERROR:Incorrent magic number in file header!!!

Hi,

Could you let me know which MCU+SDK version you are using? I assume you are using a custom board and not a TI EVM, please confirm the same. Please let me know if there are any hardware changes between the boards that are failing and the other boards.

Best Regards,

Meet.

You can also refer to this thread, where a similar issue was observed: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1211939/am2432-questions-about-failing-to-use-uart_uniflash-py-with-incorrect-magic-number-error/4572858?tisearch=e2e-sitesearch&keymatch=Incorrect%2520magic%2520number%2520in%2520file%2520header#4572858

Their issue was resolved after changing the DDR to SRAM in the linker script, as their board didn't have a DDR. Please check if something similar is needed at your end as well.

Best Regards,

Hi Meet Thakar:

      This case i have seen,i think my issue don't similar to the above case,because i can download successedly to other SOC use the same pathyon script.and i also try to changing DDR,but the result was useless。

Hi  Meet Thakar:

     Thank for your reply,i use my board and not TI's EVM,my system use 2 SOC ,witch using a common power ,One SOC can be downloaded successedly, but the other one failed to download,so i want to know werher the SOC of failed download is fault?

Hi,

Does your system have DDR? If not changing from DDR to SRAM is required.

Could you let me know the exact changes you made, or share your linker script.

Hi:

    1、AM2432 only support DDR4 and LPDDR4,don;t sopport SDRAM;

    2、Firstly,I suspect it's a FLASH fault,so I changing FLASH，but it also download failed after changing FLASH.Secondly,I seen the case you send me,I suspect it's a DDR fault,so I changing DDR，but it also download failed after changing DDR;

    3、This is we use SDK version（it incllude pathyon  script）：

    Can you tell me what other attempts I can make to further pinpoint the problem?

Hi,

Apologies for the delay. I missed this thread. Is this still an open issue? Let me know if you need any help with this.

Best Regards,

Meet.
