Flash memory programming on TMS320(L)F28x/24x

Hi,

I've been reading through some datasheets, and it seems that the only way to
programm the on-chip flash memory on the TMS320F28x or TMS320(L)F24x
families of DSP based Motion Controllers from Texas Instruments is by means
of JTAG, which means that it's MANDATORY to have a JTAG emulator. Is that
correct? Is there a way to program the on-chip flash in those devices in a
"standalone" manner, emulator independent?

All of your comments are VERY welcome!

Regards,

It's not mandatory to have a JTAG emulator.  Here's a site with some 
solutions for you:

Brad,

Is this link valid ?

http://www.spectrumdigital.com/drivers/docstore/SupportUtilities/SdFlashAlgos/C2000/SDFlash_v160_Beta2_2.zip

Can't download file for some reason.

Nordic regards,
Yuri

I can't download it either.  I see that file is dated October 29, 2004. 
It's probably just something screwed up on the web site.  Maybe you could 
email their webmaster or something.

on the 24xx you can download with a serial bootloader. Haven't looked 
for it with the 28's yet, but should still be there.

Hi,

Thanks.. What's the wiring for the serial bootloader? I saw the .zip file
from TI, but doesn't appear any schematic.

Regards,

Hi!

It uses the SCI port fo the DSP, so it's wiring is pretty much the same 
as any other SCI comm you may be using. To enable the bootloader you 
need to setup the state of some pins at startup, the datasheet gives 
some reasonable information on that (page 41).

Regards,
Ricardo

As far as I remember, these chips are loaded with a monitor program from 
the factory which you can use to write the flash via RS232. But if the 
1st trial does not work, the monitor may get overwritten and you have no 
access anymore...
