DSP56F805FV80E and FlashOverJTAG

yersr71 — Wed, 06 Mar 2019 20:45:58 GMT

Dear Sirs, please help me. With the help of the “Parallel Command Converter” programmer and “FlashOverJTAG”, I copied the P- memory and the X- memory (chip DSP56F805FV80E). As a result, I have two files readout_p.S and readout_x.S. When I try to write using “FlashOverJTAG” and the same programmer, I get a bad situation — after writing the file “readout_p.S”, I then write the file readout_x.S, and the already recorded file “readout_p.S” is erased!

What's my mistake? Maybe I need to compile the shared file “readout.S” of two (readout_p.S and readout_x.S), but I don’t know how to do this or the reason may be something else. I ask your advice.

Hi, Yury,

The DSP56F805 has dedicated program flash and data flash, the two flash are separate, so flash-over-jtag tools should erase separately.

Anyway, you can download the *.elf.S as the following screenshot, in the case, both program flash and data flash will be written. Regarding how to generate the SRecorder file, pls refer to the following screenshot.

Hope it can help you

Dear Sir Xiangjun

I do not quite understand, from your screenshot, how the SRecorder file is generated. I have two files readout_p.S and readout_x.S, do I need to rename them to readout_p.elf.S and readout_x.elf.S? But I did not understand, from the screenshot where is the link to the two files to compile? I apologize for my meticulousness.

Thank`s

Yury

Hi, Yury,

The screenshot describes how to generate the S-Recorder file with CW for DSP56800E tools, if you configure the CW for DSP56800E tools as the screenshot, the THREE S_Recorder files will be generated: readout_p.S and readout_x.S and the merged readout_x.elf.S, you can download the readout_x.elf.S, it is okay.
