It boots on my dev board without screen nor keypad, neither FPGA connected

I don't think so. You should see the Hantek square barcode logo as soon as the kernel starts


--- Quote from: tridentsx on February 02, 2015, 10:12:47 pm ---I also don't see any output on the serial connections.

That's the first thing you should see ... Did you check your soldering close enough?  :-//

I had my wife check the soldering, she is younger and has better eyesight than I have and she found a tiny bridge on the EMAC. After removing that the device boots up. I still get a failure message in the boot log.

Anyone else seen this ?
Maybe I have to get a new DM9000AEP chip and redo the whole thing and while I am at it d get a microscope as well so I can see what I am doing. :)
Thanks for the help

Yes that's quite small...

Before starting over just check you added all the needed components:
- DM9000AEP
- H1102NL magnetics
- RJHSE-5381 RJ45 jack
- 25Mhz Crystal
- 2x22pf caps

Otherwise some pictures of both sides of the board may help (near DM9000AEP and H1102NL magnetics)...

I've been out of commission for a bit. I will have to check if it's on both.   
Both channels do fails the selftest.  it was zoom unit 1 on ch1 and ch2 that fails that


--- Quote from: fremen67 on March 11, 2015, 11:59:59 pm ---Do you have the offset problem on the channel which fails the selftest only? This offset could be the reason of the selftest failure then. The relay which kicks in just activate an amplifier stage (x4 or x5). So you may have a problem with one amplifier stage...

I PMed Bugdozer who has the same hardware as yours to know wether he still has this selftest problem or not after calibration.

I finally found a HP34401A for a reasonable price so I will update the calibration tool as soon as I receive it.

Is the update calibration tool available now?

I should receive my DMM this week so I suppose this could be done at the end of the week ... if it works well  :)
