The front power led lights up as it used to do.
I can also reset the A1 using the towers reset button.

Is there any place to get a working uboot chip ?

Cant find anything at Alinea or Amigakit

The most important thing right now is to get a serial link established. As you said before, even with no RAM at all, U-Boot will say something like "No RAM detected" (I can't remember the exact words). Same if the gfx card has died, it will give you a message. It will say nothing if the CPU has died, but I would be looking at the Vcore and PSU voltages before I was convinced of that.

Don't go dismantling things, you'll only introduce more variables.

Serial link: 115200 baud, 8N1.

It is possible that a dying battery can make the NVRAM lose its settings, but even then you should get a display and a U-Boot prompt.

Understood ! I only removed all external connections, drives, PCI boards an RAM, I wont toch the CPU module yet

And yes, I will try the serial output.

I think I found a null modem cable, but they call it ''computer interface cable''
Is a null modem cable just a serial cable or is the wiring different ?
I mean pin 1 to pin 1, pin 2 to pin 2 etc..

Thanks

Martin

Null modem is NOT just a serial cable it is special. Mine says "Null modem" on it. I use it with an x86 box with amiga forever and my classic amigas.

@metalheart

if your front panel LED have a normal behaviour
(light up,blink few secondes and switch off) your system load normally
it's your AGP port,try to boot with an hold pci card(ex:voodoo ...)

if our front panel LED is still light on,the MegArray of your CPU card have a loose contact
or it is the battery but you have already change it

i have a amigaone since 8 years,I had all these failures

ah, thats what I thought about the null modem, a college of mine says he has an original null modem cable for me at home, i'll get it tomorrow.
but it has 21 pin connectors, can i use a standard 21 to 9 pin adapter for it ?

About the light, I'll look into it a little further. thanks

I'll try the Radeon in my PC, then I'll go look for a PCI GFX card.

That adaptor should be fine but serial has 25 pins. Not 21. So make sure it is null modem cable and not a parallel "laplink" cable. My null modem cable has both 25-pin and 9-pin plugs on the end.

Perhaps you could also try one stick of your RAM in both slots to test. Or your A1 RAM in a PC to make sure.

Also, when testing UBoot, any PCI or AGP VGA card should do. As UBoot will run the card in text mode which is set the same regardless. At least it should work that way.

There is a RAM guide on IntuitionBase.com. I found some compatible RAM on ebay. And recently for a friend. I looks for PC133, ECC, registered server RAM.

Once setup a 'debug terminal" will tell you what is or isn't wrong. Am invaluable resource before you go stabbing in the dark. Or prodding in it.

Final notes:
If UBoot comes up then you don't (or shouldn't) need to take it out.
NVRAM is soldered on a chip above UBoot. This is what UBoot refers to as flash. A bad CRC could also ruin it.

We patently await the results...

Well, the A1's GFX board and RAM dont fit in my PC so I cant test them...

The PSU from my PC (wich 100 percent works) also doesnt get my A1 booting, so thats of the list definately I think...

With RAM/CPU and GFX board installed, the towers power LED lights up and doesnt blink or anything and stays on.

In case of a fried CPU, is Crisot still around ?

I just got a null modem adapter (25pin) and 25 to 9 pin adapter and cable, so I guess I'll know more about this misery tonight.
If I can get the teminal program to work properly that is..... With my luck that will require quite some headaches aswel...

To be continued....

So, I'm at home, connected the nullmodem, downloaded and installed 'Realterm' on my PC....

And now ? What do I have to do next ?

Or should I use Hyperterminal ?

HyperTerminal will work fine.

Connect the null-modem to the top serial port on the XE, the other end to your PC.
Start HyperTerminal, it asks for a connection name - "AmigaONE" will do. Click OK.
Another window appears;
Set "Connect using" as COM1 (may vary depending on which port you've used on the PC). Click OK.

Bits Per Second = 115200
Data bits = 8
Parity = None
Stop bits = 1
Flow control = Hardware

Click Apply

If you need to make any changes to the above configuration;
Call/Disconnect
File/Properties

Start your AmigaONE XE and see what you get.

Fingers crossed for you.

@Metalheart

Be sure HyperTerminal config is correct.
If you're not sure you've connected the null-modem lead to COM1, just try setting COM2 in HyperTerminal and so-on.

Check out "Ports" in "Device Manager" and make sure the settings are right.

@raumfahre

I set the com1 and 2 port at 115200 and on hardware

Tried both ports in hyperterminal

nothing, it even crashed the PC

nothing, using teraterm....

I'm a little concerned about the integrity of the connection to PC, with using adapters etc.

This is the kind of cable that Hypex mentioned;
http://www.amazon.co.uk/Videk-DB25F-Modem-Cable-metres/dp/B000U06XCY/ref=sr_1_71?ie=UTF8&qid=1328729391&sr=8-71

Try pulling everything out, except the CPU.
So, all PCI/AGP cards, hard-drives, ram modules.

So all you have is the mainboard with CPU daughterboard and the serial connection to PC.
If still nothing, add a single ram module, try in both slots (also as Hypex suggested).

@raumfahre

I tried a Radeon 7200 I had laying around, no succes....

I tried the RAM in both sockets, no succes

Now I have a null modem adapter (25-25 pin) connected to a adapter (25-p pin) in my A1, and in the pc a cable 9 pin to 25 pin.

I shall go looking for a complete null modem cable..... sigh....

In case I need it: Anyone know where to get my CPU module fixed ?

Oh yes!
Had to have my own CPU module reworked 18-24 months ago
