I use OpenOCD 0.4.0 with Eclipse + yargato + ARM-USB-TINY-H(von Olimex) + AT91SAM7X256 +

ARM-elf-GCC + Zylin embedded debug.

It seems that it is almost working. I invoke in Eclipse under Run-\>External Tools a tool that I set up and get the following output in the Eclipse console:

```auto

Info : JTAG tap: sam7x256.cpu tap/device found: 0x3f0f0f0f (mfg: 0x787, part: 0xf0f0, ver: 0x3)
Info : Embedded ICE version 1
Info : sam7x256.cpu: hardware has 2 breakpoint/watchpoint units

```

This looks promising to me. I can log into telnet with the command “telnet localhost 4444” and execute a few commands. But am not sure how to associate the output with my source code. How do I have to set up my debugger in Eclipse? What does the following line mean?

```auto
Info : JTAG tap: sam7x256.cpu tap/device found: 0x3f0f0f0f (mfg: 0x787, part: 0xf0f0, ver: 0x3)

```

Thank you very much for any pointers!
