AM2634: BOOT MODE of flashing the application

Part Number: AM2634
Other Parts Discussed in Thread: UNIFLASH

Hi Champs,

I ask this for our customer.

Customers need to load the code to external FLASH. Now the method used by customers is: first use NO BOOT MODE to flash the application, and then change the boot mode to QSPI BOOT MODE to run the flashed application. This method works. But each time the boot mode is switched and reset, the code in RAM will disappear, and the customer want to know if we have a way to directly use QSPI to flash the application? It will helps a lot.

Could you please help customer check it? Thanks!

 

Best Regards,

Julia

    Hi Julia,

    There are two ways of flashing an application which MCU PLUS SDK provides OOB.

    1. SBL_UART_UNIFLASH
    2. SBL_JTAG_UNIFLASH

    SBL_UART_UNIFLASH is the application which requires to change the boot mode to UART MODE and then flash the application.
    SBL_JTAG_UNIFLASH is the application which does not mandates the boot mode. Here are the details for the same - AM263x MCU+ SDK: SBL JTAG Uniflash (ti.com)

    You can try using the JTAG_UNIFLASH utility as per the steps mentioned above.

    Let me know if this works or not.

    Best Regards,
