LAUNCHXL-F280049C: Serial Programmer

Other Parts Discussed in Thread: C2000WARE

I have tried using the USB serial port to load a hex file on to the Launchpad kit with F280049C processor, but with no success. This is all the print out I get:

C2000 Serial Firmware Upgrader

getting comm state
building comm DCB
adjusting port settings

calling f021_DownloadKernel CPU1 Kernel
Downloading flashapi_sci_kernel.txt to device...

The serial programmer sits there forever (at least 5 minutes or more). There are no flashing leds to indicate download is proceeding.

Here is the command line i am using:

.\sfp.exe -d f28004x -k flashapi_sci_kernel.txt -a MCE.hex -p COM10 -b 115200

where i renamed seriail programmer as sfp.exe.

I found the serial programmer in the following TI install directory:

c:\ti\c2000\C2000Ware_4_00_00\utilities\flash_programmers\serial_flash_programmer

Of course, the boot dip switch is set for SCI (actually I have tried every possible combo with same result).

Okay, got any help to give me?!!! Why does it just sit there.

Hello,

You can enable the verbose flag (-v) to see more detailed output while the flash kernel is loading. In addition, please try with a baud rate of 9600 for your initial test. Also, once the device is set to SCI Boot, have you tried resetting the board to ensure the device is waiting in SCI boot?

Thanks

With the -v option, one additional line is printed, "Attempting autobaud to load kernel". But proceeds no further. With various baudrates including 9600, the response is all the same.

However, after resetting the download began. All is well. Thank you for the help.

Can we continue with Phase 2 of problem. My company has a custom card using the F280049C processor. Though the serial programmer works with Launchpad is does not work with our custom card. Our card uses an identical USB connector connected to the FT232 IC and routed to SCI B of the processor. is there any hope of the serial programmer working with our card?

Phil,

The boot modes associated with the boot pins are for the first instance of the peripheral. I doubt the boot pins can be routed to SCIB, I will ask the boot expert to confirm.

Thanks

bootloaders work with first instance of the peripheral. So it doesnt work with B instance.
