TF1230 Issues

[relo999]

Can someone help me, I recently bought a TF1230 from Retroguru but can't get it to work properly. Under 3.0 it boots but only 25.9Mhz under SysInfo and can't get Addmem to work (but that might just be to my own lack of knowledge on how to get that to work proper). In an attempt to fix it I tried burning KS3.1 but that doesn't even boot when the TF1230 is installed, only giving me a black screen. KS3.1 only boots if I remove the "enable030" jumper with the Amiga functioning no different than if the card wasn't installed.

I tried mailing the builder a week ago, but got a message back from his wife that he died last week and that she doesn't know anything about it.

My own suspicious is that is has an old firmware. But I don't know, is there any way to check the firmware version?

Might be good to know, I have a 2B motherbaord with E123C and E125C removed.

Sounds like a bad build. I've never heard of a builder dying before ... jeez. Some photos?

EDIT: My gut feeling on this is that the ram is bad. Which is why it works in 3.0 and not 3.1.

Yea..

As a guess I'd say the overclocked 33mhz CPU is toast or the samsung RAM is not compatible

@relo999 Can you please edit your post and upload your images to the forum by the instructions in THIS POST if you do not know how to do it. As hot linking to external sites is not actually allowed :)

:thanksyellow:

Is there some way to check? I have a oscilloscope, multimeter and all that. Just no clue where to start testing any of that.

If the CPU wont handle 50Mhz this would also be the same symptoms. As the CPU will run at 14Mhz when talking to chipram due to my crack smoking design.

From the underside and shallow angle photos of the card the CPU appears to be soldered directly to the board without a socket so unfortunately swapping that out easily to test another is probably off the table.

Indeed soldered in, but even if it wasn't I don't have another CPU to test with.

So from what I gather advice is basically "send to a builder to get it working", correct?

This is basically how support for TF boards should work, but of course in this case it is more complicated since this person appears to be dead :(

Does anyone know who this person was?
