Hello, I'm new to the forum, as you can tell by my first post.. LOL

Great instructions you got here!

Anyways, I had purchased the M4-ATX power supply and it power up my pc just fine, but I believe I have the v1.0 board with the timing issues. I saw fox's thread (this one) about how to update the thing and I even built myself the JDM2 programmer he showed on the schematic. I had to install PortTalk on my pc because I got an error first time I tried to run winpic that the program couldn't communicate with the driver.

So anyways, long story short, I followed your instructions, Fox, and attempted to update the firmware. It starts to do the programming, which only takes a few seconds, then it says verifying for a few seconds and then it says "programming failed". Is this what you meant by the "verification fails"? Is it supposed to take longer than a few seconds on each process?

I then try plugging the USB into my PC and I go to look at the hardware properties and I believe it's still saying that it's got V1.0. According to mini-box you can check the version this way. I don't think It's getting programmed at all.

Another thing that doesn't work is the settings reset. According to the instructions for the m4, if you jump j1 and apply power, the led on the board is supposed to blink rapidly to show that it's reset to the defaults. Mine does not do that.

Any suggestions about what I can do to get the thing programmed properly? I've tried many different things and I've checked, double checked, triple checked the programmer I built to make sure that I didn't mess up somewhere. I've even tried it on different pc's but no luck.

Thanks for any help anyone can provide.
