TMS320F28335 Flash Programming

Started by polpet June 25, 2008
Dear all,

I have developed a firmware application for my TMS320F28335 with the help
of Code Composer Studio and the eZdspf28335.

The application works (quite) well in debug mode, thus I want to finally
program the flash on-chip memory in order to have the dsp working
immediately after a reset without the need of the jtag interface and
debug.

Now I'm trying to understand how to program the flash memory and I find
the SPRA8958G application report on "Running an Application from Internal
Memory on the TMS320F28xxx DSP". I tried to use the sample projects found
in the corresponding zip file but it doesn't work: when I program the DSP
with the F28335_example_nonBIOS_ram, all work properly, but when I use the
F28335_example_nonBIOS_flash program, I have the following error: "Target
halted during Flash operation. Flash operation aborted."

I have programmed the flash memory of the DSP using F28xxx On-Chip Flash
Programmer that I find under Tool and I have correctly modified the SW1
switch on the eZdspf28335 in order to have a jump to flash in boot load
option.

 Which would be the problem?

Can anyone help me?

Thank you,

Polpet

I can certainly read the manuals for you, but not here and not for free. VLV
Can anyoune help me "for free".

It's an university research project... I have not so much money!!!

Thanks

I went to http://www.google.com/search?sourceid=mozilla&q=diei.unipg.it [notice I used the Google server(s) located in USA] The first 10 hits seemed to have a number of people at your university that may be able to solve your problem or point you in the right direction. I don't speak Italian and was using Google's automatic translation facility. Good luck. [And don't take VLV too personally ;]
