TMS320F2800157-Q1: use SCI to develop bootloader, report an error "ERROR: No COM port number was specified. Please use -p to provide one."

Winni long

Tool/software:

I used board that named LAUNCHXL_F2800157.

I use the example document to develop SCI bootloader, the document link is : https://www.ti.com/cn/lit/an/zhcadf7/zhcadf7.pdf?ts=1703656598711

The first three steps were completed successfully.

When I started the upgrade action from the command line,

" serial_flash_programmer_appln.exe -d f280015x -a SCI_2800157_SCI_GPIO_Toggle_App.txt -b 9600 -p COM37 "

I got an error message like the following :

" ERROR: No COM port number was specified. Please use -p to provide one.
getting comm state
building comm DCB
adjusting port settings "

I think it may because of the document describe error, I already try the another COM , but the error is the same one.

Hi Winni,

What does your device manager say the COM port is? Can you check if the COM port hasn't moved?

Thanks,

Charles

Hi Charles Roberson ，

In my first picture ， I show the device manager message that indicated which the COM port is. I didn`t moved them.

And I try to use serial assistant to communicate with PC , it often tell me that "The serial port is used or does not exist"

But I use ccs to programming , it works well .

Hi Winni,

For using the appln version of the host programmer, you still need to provide the argument for the kernel (-k ). It will be bypassed but is necessary for input.

Thanks and regards,

Charles
