Hantek HDG2002B AWG: 5Mhz or 100MHz? Let's see!
<< < (79/134) > >>
scope sam:
Recently I bought an HDG2082B, the manufacturer had given me a calibration software. The calibration procedure is as followed.



The total procedures are 104 steps. I have tested and successed at one time.

I've just soldered the following components to enable ethernet on my HDG2000B series generator:
DM9000, 25MHz xtal, 2x22pF,  LAN1102 magnetics, ethernet connector.

When the system boots up I get the following trace:
dm9000 Ethernet Driver, V1.31
dm9000 dm9000: eth%d: Invalid ethernet MAC address. Please set using ifconfig
eth0: dm9000e at c4b22300,c4b24308 IRQ 48 MAC: a2:aa:fd:39:d3:74 (random)
dm9000 dm9000: eth0: link down
dm9000 dm9000: eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

I've configured a static IP via the menu but when I try to ping it it's not working. The green LED is lit when I have the cable plugged in but I'm worried that I'might still missing some components. On the back of the PCB there are traces from the eth connector to U6,U7 and some other components that are missing.

Can someone with a working LAN let me know if I'm missing components or the IP menu configuration is not working?

@zelea2: I compared the modifications that you did and the various bits and pieces on your PCB to mine, and it all looks the same (or very similar). I would recommend (since I ran into this), reflow the crystal; I had a problem with my soldering on this part and it caused the ethernet to not work in the manner you describe (although I didn't use a can like you did, I used a 4-pad SMD crystal).

There are no more components to add.
Try to change directly the IP address in /dso/etc/boot.sh. It should be 192.168.1.127 by default:

ifconfig eth0 192.168.1.127 up

Not sure the modification through the utility menu will work after a reboot
Edit: could you post your Hardware&Software version?

Very interesting. Could you post the software or a link to it?
