TI Flash Agent and Blackhawk FlashBurn

tom prohaszka

I have a question regarding the TI Flash Agent. I'm generating a Motorola SRECORD via hex2000. Below is an output line from the file:

S2223E8000FFFFFFFF33441122AA55AA550200004D006100790020003200360020003278

When I use CCSv4 to flash the COFF file (F28035), the memory looks like this:

FFFFFFFF33441122AA55AA550200004D006100790020003200360020032

So, the srecord text looks ok.

I'm using the Blackhawk Flash burn utility to load the srecord, but when I use that to flash the file, the memory looks like this:

FFFFFFFF4433221155AA55AA00024D00610079002000320036002003200

The byte order is swaped!

Talking with blackhawk support, they claim to be using the TI Flash Agent. I'm trying to determine if:

- I can modify the flash agent to swap the bytes

-Have hex2000 generate byte swaps

-Determine if this is a bug in Flashburn

Any ideas?!

Tom,

I don't know for sure if you can swap the byte order but the reference guide that describes the hex2000 utility is http://www.ti.com/litv/pdf/spru513d . See Chapter 11.

I think there is an issue with the flashburn, I'm working with Blackhawk to confirm.

I received a response from Blackhawk( THANKS JOE!)

The BHFlashburn tool does work, but requires the srecord bytes be swapped. There are additional options in hex2000.exe not in the manual, in particular a --swapbytes option.

Here is the command line example:

----------

The HEX-file generated with "hex2000.exe -m2 --romwidth=16 <coff-file> -o <hex-file>.hex" command line is in big-endian byte order (not sure why), even if the source COFF-file is in little-endian order.

To fix the above issue use the "--swapbytes" option to generate a HEX-file in the correct byte order for use by BhFlashBurn.
