TMS320F280039C: UART/SCI Based of Code Flashing with bootloader

Part Number: TMS320F280039C


Hello team TI, 

I am using above mentioned DSP (100 Pin package) for my control card.

I want to flash with bootloader using UART/SCIA pins,

I have ensured the status of the GPIO 24 and 32 as per the table7.8 given within the datasheet.

please guide me on which pins i should use as Tx and Rx from the following sets,

is there any additional setting to be done if i select particular couple of pin

Pin Sets: - (SCIA_TX, SCIA_RX) :: (77,76); (74,90); (54,55); (56,57); (100,1); (61,63); (7,8)

Also, do i need to use a third party tool such as C2prog or i can do it with CCS with some additional settings?

Regards,
Rushiraj

    Hi Rushiraj,

    For the F280039C device 100-pin package, you can use these combinations from the given pin set for SCIA:

    (77,76) - reference GPIO2 and GPIO3

    (54,55) - reference GPIO16 and GPIO17

    (100,1) - reference GPIO29 and GPIO28 (default option)

    Based on pin select, you will also need to modify the SCI Flash Kernel project with the appropriate bootmode value if you plan to use these pins for a firmware update. A third party tool is optional. If testing with CCS, you will need to set the emulation-bootpin-config boot config register to the required BOOTDEF value. 

    If any further questions let me know.

    Thanks and regards,

    Charles
