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?
Regards,
Brian
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,
Charles
