Part Number: TMS320F28335
Other Parts Discussed in Thread: UNIFLASH

Hello All,

I have few hardware boards based around TMS320F28335.

I am using the following:

- Code Composer Studio 8 as software.

- Spectrum Digital XDS510 USB as the emulator for JTAG connection.

Some of my boards have a particular version of DSP program and are working as required. Other boards have DSP programmed with some other program.

I do not have either the source code or program image files.

Using the CCS 8 and XDS510 emulator, I want to readback the programmed file from any working board and then using the same file want to reprogram the boards which are not working as desired.

It would be great if someone can guide me with step-by-step procedure to do this.

Thanks,

Amit

Hi Amit,

I will try to see if I can find instructions for this tomorrow.

Is there any security protection on these devices?

Best Regards,

Ben Collier

Hi,

Could you see if this thread helps? https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/643171/ccs-tms320f28335-how-to-read-out-program-flash-using-ccs-or-uniflash

I think you will need to save the memory from good your device as a .bin file, then load it as a .bin to the same address that you saved it from. I think you will need to do this for all flash. You also may need to use UNIFLASH and a different debug probe for this, since I am not sure if XDS510 is supported in the newest versions.

Best Regards,
