As per this post:
I have the same issue I have a board and have a TMX320LF2407A IC with a JTAG header. I have a XDS510LC
USB JTAG Emulator from spectrum digital. I have downloaded CCS3.3 and I can connect to the controller using JTAG. I can run and stop the processor thus my connection is ok. Since the TMS320LF2407A is not DSP read protected, I am able to save the contents of the TMS320LF2407A with the following steps.
File/Data/Save../Coff(*.out)
“Storing Memory into File”
“Address: 0x0000”
“Length: 0x8000”
“Page: Program”
“DATA”
“ I/O”
1-Before saving, a small window titled "Storing Memory Into File" appears, as in the photo above, and there are three options for saving in this window, "Program-Data-I/O"
Which of these should I choose when saving? "Program" or "Data" or "I/O"
2- I have one working and one broken PCB's with this DSP on them. When I save the "Program" and "Data" in the DSP of the defective PCB separately and save the intact DSP in the same way, I saw that the "Data" codes of the non-working card were deleted, the "Program" codes are exactly the same when I compare them to the intact card. that is, only the "Data" part of the faulty card has been deleted.
3- How can I upload the "Program-Data-I/O" files in (Coff.out) format that I got from the TMS320LF2407A, which works without any problems, separately from the "On-Chip Flash Programmer" window?
For example, how can I load (program) only the "Data" file.
4- When flashing another Data file from the TMS320LF2407A (On-chip Flash programming) window to the old DSP, in the clear step, gives the error message; "Error: Read status value 0x0001 from symbol PRG_status
Flash algorithm failed during clear operation". How can I resolve this situation?
Please take a look at the memory map of the device below:
Flash, which is non-volatile, is only mapped in the Program space. It contains the firmware, which is what people typically try to copy from one device and program it on another. The concept of "programming" only applies to flash.
All memory in the Data space is volatile. These memories are used by the firmware to store variables, tables and intermediate results. You can "save" contents in the data space, but it is meaningless to "program" them. RAM in the data space is written to by your firmware. It is not "programmed" by you.
If this is still not clear, we need to get on a call. It would help if you can send the schematics to me privately so that I can check if there is any non-volatile memory in the data space.
Dear Hareesh
Thank you very much for your valuable information. As you said, VPP was giving that error because it was not 5 volts, now I have VPP 5 volts, it erased the DSP, but it gives this error during the Flash programing phase "Conversion aborted: This file is not linked"
