So hoping for some assistance or advice! Due to being quite busy I started my weecee build quite some time ago, and then had to leave it for a while before I finished it off (last few resistors etc.) just today! I was actually considering buying that one that was on ebay relatively recently, and am now severely regretting it as unfortunately I appear to have not done something correctly, and I dont really have a lot of time to troubleshoot, so!

finished off my weecee, hooked it up, and it looked good to start with. The COP unit lit up, the keyboard lit up, and after a short while, the ethernet port lit up as well, but, I didnt appear to be getting any image from the unit (this is running through an RGBs SCART/AV/VGA > HDMI converter that I know to be working) I checked continuity from the pins on the board for VGA to the end of my VGA cable and all had correct continuity.

Unfortunately in the process of unplugging it and troubleshooting, I ripped the USB power port off the board.

If anyone has any thoughts on where to start looking for whats up with it, that would be greatly appreciated. If anyone is in NSW Australia and would have the time to look at it and fix it for me (with payment), even better. Failing all that if someone is selling one, but I think I want to get this one going.

Have you checked your soldering on the header that attaches the SOM to the board? sometimes, even if they look solid, it's possible there's a bridge somewhere or it's not fully connected. also, make sure the connectors on the bottom of your SOM are in good shape. I've seen them break before even if you're being careful.

good luck!

I think you might just have a VGA to DVI-A cable, it only has wires for the analog VGA signals and can't be used for any real DVI-I or DVI-D application.

Ive tried it now with a VGA cable and get the same issue, no picture. not sure what to do to trouble shoot this unfortunately.

Kinda wishing for at least a known working populated board sans SOM that I could buy to test - not sure where to even start without another system to start eliminating possibilities 😒 hmms

Send me a PM and we'll set it up.

I dont have access to PM yet 🙁

Thanks 😀

Ive checked for bridges with my multimeter, definitely none so thats good

ill go over and resolder for the header again just to be sure, see how it goes 😀

Would X2GS SE fit and work with weecee instead of S2?

@Emerson Wagner

Nope, not enough space.

Went through it again today and resoldered all the headers to the SoM - Im pretty confident they are good, and no bridges found with the multimeter. still no success 🙁

Ive definitely done something wrong somewhere, just not sure what now.

can you send some updated pictures of everything? it's probably something minor somewhere. it always is! at least in my case 😉

Here you go, Ive tried to get good angles on it as best as I can. I can give close ups on particular areas if it might help identify whats up

From the pictures everything looks ok. I’m wondering, can you check all the vga pins for continuity to ground? The first time I tried buildings one of these I somehow bridged some of the traces and grounded out the vga which would prevented it from showing picture. I’ve built about 4 of these now so worst case scenario I could send you a working board if you pay shipping. That way you can at least test against yours.
The only other thing I can think of is to try to clean some of the flux off the bottom and see if that helps. Probably won’t do much but couldn’t hurt.
The vga connection is a straight shot to the SOM so there’s not even any passives that could be mis-soldered.
The only pins that should go to ground on VGA are 5-8 and 10 and then 5v on 9 only. Give that a look and let me know!

Grounds have come up fine

pin 9 is getting 4.6v (powered by USB port on a power board plugged into the wall)

That’s good! Do you happen to have an oscilloscope? If so, check the RGB lines and see if there’s any signal on them when powered on. Should be pins 1-3

I dont have an oscilloscope unfortunately no 🙁

Have you ever figured out any way to disable S2 without pulling it out? There are sometimes rare situations when I wish I could use it instead.

Short of adding a mechanical switch on top of cut traces, I don't see how personally. So I haven't.

So I found some solution to disable midi module... kind of. Hear me out 😀
Due to my issues with random keystrokes in the weecee I purchased, that I described here, I gave up on it. I purchased other similar project, pixelx86 and I got the X2GS SE for it from Serdashop. That module has 2 banks for soundfonts, one is Roland licensed sc55 preset, the other is user bank that can be flashed with custom soundpack. You can switch between those banks with simple command from dosprompt. So I simply flashed user bank with blank file. So when I want to use external device through midi port, I switch to user bank and let my Rolands play, while midi module thinks it's playing but it's silent. It's stupid, but it works as intended.
The problem is, pixel has enough space for x2 module, while weecee does not.
But to stay ontopic, I actually fit it in weecee, little angled, to test it. And it works. I just can't slide it back into case.
So I know it's not really a solution for weecee, but some it is some kind of possible avenue I guess. A module of the size of s2, that could switch to "silent" set of intruments?

would a GS version of X2TE (X2 tiny edition) be a solution ?
it is only 35mm x 25mm in size , see https://www.serdashop.com/X2TE
if interested, send me a PM

I haven't messed with the weecee in a while, but the S2 is wired into the LINE IN of the crystal audio chip.

I think you should be able to mute the S2 using either the crystal audio drivers volume utility or passing a volume zero parameter to unisound.

I think it would! As long as it comes with bank select option to switch instrument packs quickly from prompt. It's only 1mm longer than S2 on each edge, and S2 is a perfect weecee fit. I'm not sure about the thickness as it would come with usb port I assume. There's little space below (weecee's vga port internals) and above (flat case).

Yeah, you mentioned it about a year ago. I, along with a couple of other people here, tried but to no avail. External and internal midi always play together, and there seems to be no way to separate them.

I also have a special edition X2TU, without USB connector, which i can pre-program.
this should sure fit. - you could try either X2TE or X2TU -> send me a pm !

By curiousity, did anyone of you owning a weecee try BeOS on it?
