AWR2944: uniflash with custom JSON file for custom flash MX25R6435F failed

Tool/software:

Hi,

 We are using AWR2944 with a cutom flash MX25R6435F. We have a custom JSON file made for this purpose and loaded the same in the sysconfig to get a custom sbl_qspi_bootloader using the TI SDK 4.7.1. We are not able to flash. I am attaching the error that we get in both the uniflash and in using the uart_uniflash.py. Please advice on how to go about in getting the flash working.

Thanks

Anand

    Hello,

    In order to get more info on the issue at hand you will need to build your own sbl_uart_uniflash application and place a loop_forever() function in order to step through the code.

    C:\ti\mmwave_mcuplus_sdk_04_07_00_01\mcu_plus_sdk_awr294x_10_00_00_07\examples\drivers\boot\sbl_uart_uniflash\awr294x-evm\r5fss0-0_nortos

    Here is the location of the example driver code that you can build yourself and replace the sbl_uart_uniflash.release.tiimage with your own.

    Once a loop_forever() is placed and your application is built you can do the same flashing process that fails, but this time once it fails you can load the symbols on CCS and you can step through the code to get a better look at what could be causing the issue. Since you are using a custom flash it could be a multitude of issues causing a problem.

    Best,

    Gabriel
