Hello Alex,
Do you have the display of some informations on your serial port when you start the digibutler ?
Is your Digibutler respond to a ping ?

No. I'm pretty sure I've made the proper settings to hyper terminal but I'm not getting anything written in the window when it connects. Tried to connect it after digibutler starts, before digibutler starts and nothing. Also I've made sure that the settings are properly made for Baud rate and control bit etc.
I wan't able to get a ping this time. But last time I was getting a ping on it. But I wasn't able to connect to it at all. Not via 192.168.0.151 not by the external IP forwarded by the router. And last time it took it about 30 minutes to respond to ping.

I think you should first check why your serial port is down, it's the easiest way to verify that your Digibutler is alive.

I'll try. I've got a usb-serial transformer. So that might be the issue (as stated in the elektor magazine too). So I'm gonna get an old laptop and see if a true serial port will fix the issue. Otherwise I've no idea how to fix it.

I've tried connecting via serial to the digibutler and I get nothing. The screen remains blank still. So I'm guessing it's a hardware error. I've tried running a Hardware Diagnostics (below the flash programmer). But for every test I get an error that it cannot read memory ("ColdFire GDI Protocol Adapter : An error occurred while trying to read memory").

Oh and when I check out the memory in dissasembly code i see this most of the time (90% of the rows are like this):
0000000A: 0424 dc.w 0x0424 ; Invalid opcode
0000000C: 0000 dc.w 0x0000 ; Invalid opcode
This is all the time. Even when the board is erased. The values 0424 and 0000 as well as the command dc.w are always there.

You have no error when you run a make command ?

Good morning Tigris,
No. I have no error whatsoever. The checksum is the same on the host as it is on the target so the program is properly written on the Digibutler.
Is it right for the Device Initialization not to have the FEC module enabled? Only by generating code are those pins enabled in the Graphical description of the CPU.
