Hi, Is anyone using the XDS510PP Plus JTAG emulator together with the TMX320VC5510GGW20 DSP ? We have used this emulator on another DSP from Texas, and I want to use it on this new DSP now. I contacted Spectrum Digital a while ago, and they send me the necessary driver for the 5510 DSP and Code Composer Studio. I am not able to connect to the DSP using Code Composer Studio. I have verified the connection with the SDConfig program from Spectrum Digital, but it looks like there is a bug in the DSP. This is the result I get when I am trying to verify the emulator settings with SDConfig: ** Checking for a valid emulator/eZdsp $$ You are connected to: $$ EmuProductName=XDS510PP_PLUS $$ EmuPortAddr=0x378 $$ EmuPortMode=SPP8 $$ ProductId $$ ProductVersion ** Checking emulator/eZdsp scan connection ** Emulator Test ** $$ EmuProductName=XDS510PP_PLUS $$ EmuPortAddr=0x378 $$ EmuPortMode=EPP $$ ProductId $$ ProductVersion ** Emulator Scan Test -- Found JTAG IR length of 46 -- Found 2 JTAG device(s) in the scan chain The SDConfig program has detected 2 JTAG devices, but there is only one DSP on my target connected to the JTAG. The JTAG IR length is 46 but it should have been 38 (as described in SDConfig.htm). I have checked my hardware, and I cannot find anything wrong. The DSP is connected to the JTAG connector as described in the Pp_plus.pdf document from Spectrum Digital. I have asked Spectrum Digital about this problem, and here is their answer: The problem is the C5510 DSP. There is a bug in the silicon you have that shows two JTAG devices: 1 C5510 with 38 IR length, and 1 ? (bypass) with 8 IR Length. The SDConfig has shown that you can communicate with the part. Make sure you set up Code Composer Studio corresponding to the two JTAG devices. I have tried to set up Code Composer Studio with two JTAG devices, but I get the following error message when I try to start code Composer Studio: Can't Initialize Target CPU: Target initialization failed. Check target power, and JTAG connection. I/O-port78 Board name:sdgo55xx Cpu Name: CPU1 So, back to my first question. Does anyone use the XDS510PP Plus emulator on the TMX320VC5510 DSP. If so, wich version of the DSP do you use. I am not sure if this is a bug in the 2.0 device or not. I will try to connect it to a 1.2 device to see if this works better.
