Compiler/AWR1843BOOST: Flash firmware with CAN

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1642, UNIFLASH

Tool/software: TI C/C++ Compiler

Hi Team,

      My customer would like to know whether it is possible to upload the MSS/DSS/BSS bin file into the QSPI flash on a brand new, never programmed/flashed AWR1642/1843 radar board through CAN-FD. I know we can flash it with Uniflash and then use Secondary Boot Loader to download new image files. But can we totally get rid of the UART and Uniflash?

Thank you

    Please see Bootloader Flow Appnote

    https://www.ti.com/lit/an/swra551/swra551.pdf

    If a flash is not available in the system, then SPI boot must be used.

    If a flash is available but there is empty the device will not boot.

    So, it is not possible to boot through CAN-FD

    thank you

    Hi Cesar,

         Thank you for your quick reply. 

         So please let me make sure, the AWR1642/1843 can recognize the UART cmd when it is an empty chip (never programmed/flashed) and download the firmware through UART from PC then transfer it to FLASH through QSPI. Am I right?

         Is that possible that an empty radar chip can download the firmware through CAN-FD and transfer to FLASH through QSPI? If this works, that will save us a lots of time.

         Or if I can write the firmware to FLASH via CAN-FD and then the FLASH could boot an empty radar chip, is this correct?

    Thank you
