Other Parts Discussed in Thread: C2000WARE
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?
