I'm working with Nallatech BallySHARC module and I have a problem to boot DSP through JTAG cable because it's done correctly only if I load on the FPGA the Nallatech bitstream and not my bitstream... Does anybody help me????Does anybody work with this board???? thank every body... Dario This message was sent using the Comp.DSP web interface on www.DSPRelated.com

Did you ask technical support at Nallatech?

Nallatech support didn't answer to my question. I don't know what i can do.>Did you ask technical support at Nallatech?

Mmmhhhh.... I dont' know that board at all, so i am just wondering. Maybe the FPGA interfaces to the JTAG pins on the DSP too, and it's default bitstream has what it takes to CORRECTLY letting you use a JTAG cable for programming the DSP. Could you verify that? Are the schematics available to you? JaaC Dario wrote:> Nallatech support didn't answer to my question. > I don't know what i can do. > > > >Did you ask technical support at Nallatech?

The schematics are not available and i can't recompile the nallatech project because it's incomplete. I think that the documentation it's incomplete about JTAG or other required feature for the FPGA. It's possible some kind of reverse engineering on the bitstream? Dario>Mmmhhhh....
