@Hans

Sorry, no progress yet. I'm busy with my daily job at the moment so that there's no time left for the AmigaOne. I hope I have more time for the project in October (fingers crossed).

Resurrecting this old thread, I have three photos of the PCB layout on an A1SE, made by an user on amiganews.it:

(the first three photos in the album)

I have asked the author to verify if the printed PCB measurements were correct, unfortunately I got no answer from him, I hope that the photos will be anyway useful.

Thanks a lot for your help!

I'm afraid he put the layout on the wrong chip! The flash ROM is on the same position as on the A1XE boards.
But now I see that the AMR slot uses the space I need for the second flash ROM on the PCB. That's really bad! Maybe we find some PLCC plugs that are higher than a PCI slot connector. Otherwise I don't see a posibility to use the DualUbootA1 PCB in the A1SE. Unfortunately that also means you can't use the nearby PCI slot.

BTW: I just ordered two PCBs, which I'm going to solder over the christmas holidays. Actually I wanted to do that earlier, but as usual there were a lot of other things to do.

Another thought. Since AMR slot was never actually used for anything, why not remove the slot connector for it? :)

As I remember there were a few different height options for the PLCC plugs. I forget what the max was, but perhaps a couple could be stacked f really needed.

Or just use ths slot to support a dummy card? No fingers on the card.

I would rather like to avoid that.

That's probably the best option.

Actually a PCI card with the two flash ROMs would work for all A1, but occupies a precious PCI slot.

@all
The PCBs arrived today. I didn't check, if they still fit. But let's hope for the best.

I built up one DualUBootA1XE PCB yesterday. It was a little bit tricky to solder the PLCC plug with the shortened pins and the PLCC sockets (looks like my solder skills are a little bit rusty or it is time for a new solder station ). Anyway here's the result:





Actually I planned to solder a second PCB too, but unfortunately I only ordered two PLCC sockets from Farnell. Now I just need to find some spare time to test it out in my A1XE when I have access to it again.

Looks good!

Okay, I guess that means that I have your approval to go on with the functional test.

@billt
I could send you the other PCB, if you want. At least after I'm sure that the soldered one works correctly in my A1XE.

@all
Is there anybody else interested in testing new U-Boot versions in their A1SE and microA1 machines besides billt and me (we only have A1XE machines) in the future? I would just like to know, if it makes sense that I'll continue working on PCBs for these machines or if it is better to concentrate on the code now.

I would love to do massive testings
with my A1XE933.

Is there a chance to get a PCB?

Greetings

Here too XE, no more than 800 to 933.. Must stop testing. Too much distance I beleive?

Please test and I'll buy a reasonable priced add-on to the XE.

PM-Then. Thanks.

@zErec

Sorry, I only have two PCBs at the moment. They were a little bit expensive, because I didn't order them "correctly". But if two or three other peoples are interested, then it would make sense to order another batch.

BTW the Eagle files are available on our uboot-amigaone project homepage, so feel free to do with it whatever you want.

@PR
The PCBs won't be cheap. The PLCC plug on the bottom side of the PCB already costs ca. 20¤.

I think it's worth asking if people want these boards again when a new version of Uboot is ready for public release.

I'm sure there are quite a few owners who'd appreciate the extra peace of mind when flashing their ROM.

That's true and a new U-Boot release will not be available in the near future.

On the other side I'm searching also for microA1 owners that would like to support the uboot-amigaone project by testing U-Boot development versions (which could break booting). Users that flash a real new U-Boot release shouldn't need a DualUBootA1 PCB.

Pm sent for help at the beta test with my mAmigaOne.

Here's the first photo of the mounted PCB:



Programming one of the flash ROMs works fine and the write protection works, too.

Now I just need to attach a small DIP switch to the PCB so that I can easily switch between the two flash ROMs without opening the machine.

Excellent work Gary, I think this deign might be useful other projects in the future too, officious not the most complicated thing, but you need the equipment and parts, and there is officious as risk attaching some thing that have never been in use/ tested, its so easy to make mistakes.
