TMS320LF2407A: TMS320LF2407PGEA cloning

user5814666

Part Number: TMS320LF2407A

Hi everyone, i am fixing an industrial board that has no more sobstitutes and the company that makes doesn't document these anymore.

It has an old dsp TMS 320LF2407PGEA with a faulty PWM i/o on it, causing it to be unable to control correctly an array of solenoids. i have succesfully purchased a New old stock of the same TMS but of course i need to program the fw contained in the old one into the new one. Can anyone please point me where i can purchase the software and the hardware programmer needed to dump the fw of the old tms into the new one? thank you.

Nick.

Another option would be www.codeskin.com/c2prog-faq

See attached file for helpful tips.Codeskin.pdf

I checked with a colleague and he mentioned that only DSPHEX.exe would work (not HEX2000.exe). Here is what you need to do: (If the device is secure, I hope you know the passwords)

Connect the device to CCS3.3 and save the flash contents as a COFF file (.out file).

Use DSPHEX to convert it to a hex file.

Connect the fresh device to the PC’s serial port and program the flash as outlined in the attachment.7510.Codeskin.pdf

hi, sorry for not replying earlier, been kinda busy. thank you for all the resources. my board doesn't have In site programming headers, jtag or serial. hopefully I can connect directly to the ic using the pinout on the datasheet while powering it with my bench psu or the board itself. This Monday I will be back on it and hopefully I can pull this off, I also hope noise will not be too problematic considering how small the wires I will need to solder on are

so, one of the boards is slightly different from the others. looks like it was for debugging or something because lot of components are labelled and this one has what it seems to be a 14pin TI jtag header near the TMS. that should make things easier hopefully

You need a working copy of CCS3.3 on a PC and a debug probe like XDS510PP+. If you have these, then you could connect to the device via JTAG and easily dump the flash contents.

hello and thank you so much for the help so far. XDS510PP is a bit hard for me to get here in Italy, is there any cheaper or more modern/readily available alternative? I have never worked on these old-ish DSP before so i am very ignorant on the subject
