TMS320F280049: Error reported for serial flash programmer

Part Number: TMS320F280049
Other Parts Discussed in Thread: C2000WARE

Hi team,

My customer is using serial_flash_programmer_appln.exe to achieve firmware update function. They are upgrading the F/W with the following commands:

serial_flash_programmer_appln.exe -d f28004x -a led_ex1_blinky.txt -b 9600 -p COM16

Even with the -p COM<> in command line, sometimes they would also get the error report:

Error: No COM port number was specified. Please use -p to provide one.

getting comm state

building comm DCB

adjusting port settings

Though there is error report, the download would still succeed. 

Since we have limited knowledge of composing a host program, could you kindly check if there is some bug in serial_flash_programmer_appln.exe? Why the -p command seems not working?



  • Hi Brian,

    Few things:

    1) Have they loaded the kernel to the device using CCS first?

    2) Is there another device listed for COM16?

    3) What is the build configuration listed as for the kernel? I am using the RAM configuration.

    4) Is it possible to ask them to add the "- v" argument with their command line to see verbose output?

    5) What version of the serial_flash_programmer_appln.exe are they using? I tested with the recent C2000ware_5_00_00 version provided and am able to flash the device.

    6) Is this a regular firmware update or live firmware update?

    Thanks and regards,
