I have added files at the end of the post. I believe you can improve PCB routing. Sorry somehow it wasn’t attached. I have added files at the end of the post. I believe you can improve PCB routing.

It works for me as simple dev board. But you are welcome to look at schematics and trace your own PCB. I Agree that leaving copper islands is bad idea - better to ground them or not to put at all.

This is never a good idea. It can help noise to capacitive coupling to other traces, although you have no problems in good function. Better to join pour copper to ground and never leave islands of pour copper (i mean don't join in 1 only place the pour, stitch with vias to ground in more than 1 place to avoid islands). On other hand, i wanted to thanks your blog, because i'm doing my first arm7 board and i'm looking your schematic to base my board on yours. Why did you leave pour copper isolated?

As far as I have tested this one - it worked OK. You are welcome to do it board fits your needs. As far as I have tested this one – it worked OK.

Can I go ahead with your design? I just want to test ARM's powers, and am plannning to program it from RS232. Hi

Adapter is Olimex ARM JTAG clone which is easy to build and works with WinARM tools (ocdremote and gdb/Insight-gdb). Circuit is here: <a href="http://winarm.scienceprog.com/arm-development-tools/jtag-wiggler-clone-for-arm-microcontrollers.html" rel="nofollow">JTAG wiggler clone</a> I haven’t build it yet, but I am going to build one soon.
