Hi, I am having problems connecting to my DSP56311 using Crossview Pro. My target hardware has 3 devices on the jtag in the following order: 1) Xilinx Prom (Jtag reg len 8) 2) Xilinx Spartan2E (reg len 5) 3) DSP56311. I am using a parallel port command converter I have modified the default parallel config file as below to add the additional devices(I found the documentation a bit ambiguous). Can anyone please help me as I'm not sure if I have added it in the right way. My setup works with only one device on the chain (AKA EVM board), and the jtag chain is complete as seen from the xilinx tools. Additional information: If I utilise the default parallel config file, then the TDI pin on the JTAG does its thing, however if I use the modified multiple device config file it appears as if Crossview has problems as their is no data ouput on the jtag pins. Also if I disconnect the Jtag from the board the errors in the above 2 cases are different. With the single device setup the error is "Cannot connect to device" and in the multiple device it is "configuration 56311 not supported by target" Help! Scott.

Multiple jtag devices in chain

The Motorola OnCE port has trouble with none OnCE devices in the chain. While the JTAG has no problems, often times the OnCE protocol does. It's best to keep the DSP(s) on a separate bus... -- dB --- ukkiwikid <> wrote: > > Hi, > I am having problems connecting to my DSP56311 using Crossview Pro. > > My target hardware has 3 devices on the jtag in the following order: > 1) Xilinx Prom (Jtag reg len 8) > 2) Xilinx Spartan2E (reg len 5) > 3) DSP56311. > I am using a parallel port command converter > > I have modified the default parallel config file as below to add > the additional devices(I found the documentation a bit ambiguous). > > Can anyone please help me as I'm not sure if I have added it in the > right way. > My setup works with only one device on the chain (AKA EVM board), > and the jtag chain is complete as seen from the xilinx tools. > > Additional information: > If I utilise the default parallel config file, then the TDI pin on > the JTAG does its thing, however if I use the modified multiple > device config file it appears as if Crossview has problems as their > is no data ouput on the jtag pins. > > Also if I disconnect the Jtag from the board the errors in the above > 2 cases are different.
