I think the troubleshooting in this case is of quite general nature and could be interesting for other users, is it ok with you if I move this topic from helpdesk to the open part of the forum?
I always prefer using ethernet to update my MD4 modules. The firmware of the MD4 is about 20 MB, so updating it via 250 kbit/s CAN will take time. When shipped from our production, the MD4:s are loaded with all the firmware, but almost always an earlier version than the latest available.
But both methods should work though. Starting with the attempt at downloading via ethernet, how were you connected to the MD4? E.g. laptop disconnected from the docking station and the office network, with a cable directly to the C3 connector? Or the MD4 C3 connector plugged into the office network?
What you could have is that the ethernet port on you PC has been blocked for certain types of traffic. This would be something to suspect if IQANdesign/IQANrun does not find the MD4 at all.
If the CAN download fails, that is more likely to be due to the CAN wiring. What CAN dongle are you using, and how is it wired? E.g. 120 ohm termination on the CAN dongle, and just the MD4 as the only module on the bus. Or a more complex CAN network with multiple IQAN and non-IQAN modules on the diagnostics bus?
Good point, we missed this symbol. It will be added to the image library.
