BF592 EZ-KIT Jtag Conection using bfin-gdbproxy

Hi yanming,

Do you use the IGLOO parallel cable? Thanks,

Jie

Hi Jie,

     Yes. That IGLOO parallel cable came with HHCN BF531 board, which I bought few years ago and worked all the time with that board. Now I want to tried that cable with BF592 EZ-Kit board. I happened having an old notebook (more than 10 years old) that has a build-in parallel port.

Hi yanming,

Could you please post the complete console output from gdbproxy? Thank you,

Jie

Hi Jie,

   OK. I will do it during the coming weekend.

Hi Jie,

    This is the output from Jtag command:

please try running bfin-jtag , then type these commands:

jtag> cable IGLOO parallel 0x378

jtag> detect

Hi Jie,

    This is the output after running bfin-jtag command on BF592 EZ-KIT board:

Thanks. There is a builtin emulator on BF592 EZ-KIT board. You need to connect pin 1 of the JTAG connector (P2) to ground to bypass it so you can use an external emulator connected to P2. To do that, you can just connect Pin1 to one of Pin7, Pin9, Pin11 or Pin13 on JTAG connector (P2).

Hi Jie,

   Thank you for your reply. I will try it when I get time (maybe during CNY). I still have a question based on your solution: I connected this BF592 EZ-Kit before via JTAG using ADI original ADZS-USB-ICE.  The software I use is VisualDSP 5.0. But I did not do anything to the JTAG interface. I can single step cod via that JTAG interface.  How did this happen?

That's because ADZS-USB-ICE does connect Pin1 to the ground internally. IGLOO was designed too early to have the feature to bypass the on-board emulator.
