Hi,
I have developed a JTAG board to implement the XDS100v2, which it has the function to translate the USB protocol to JTAG protocol. I have used the same schematic of the Concerto F28M35xx controlCARD, figured in the next page:”USB to JTAG, digital iso, serial debug”. Then I have started programming the control card of Concerto F28M35xx. I have created an empty program in Code Composer v5 and I have configured the JTAG Emulator used. In this case in the option Connection I select: “Texas Instruments XDS100v2 USB Emulator” and in the option Board or Device I have select: “F28M35H52C1”. First of all, I have done the test connection and it doesn’t fail. Afterwards, I build the empty project and download it to the concerto and the programs runs correctly.
However, I do the same with the personal JTAG board connected to a control board with a TMS320F2808 DSP. Then I change the target configuration: in the option Connection I select: “Texas Instruments XDS100v2 USB Emulator” but in the option Board or Device I have select: “TMS320F2808”. First, I do the test connection and the result are positive. Afterwards, I try to build the empty project but I receive the next error message:
Error connecting to the target:
(Errorr -1135 @ 0x0) The emulator reported an error. Confirm emulator configuration and connections, reset the emulator, and retry the operation.
(Emulation package 5.1.450.0)).
Then I can’t download the C project to the DSP. But how it is possible if I can realize the test connection satisfactorily and I can’t download the program to the DSP? I understand when the test connection is run the information flows from the PC to the DSP and vice versa. Which could be the source error?
Thanks for your help.
