N+2 ethernet not link

Hi everybody,

We recently receive from Mouser Spain 4 Netduino Plus 2. Two of them does not link with my network, I mean, the activity green led does not blink.

Do you have any suggestion before I contact with the supplier for an RMA?

Thanks in advance,


Have you checked the network configuration using MFDeploy?


Hi Mark,

As always thanks for your interest and quick answer.

Yes, I do it, everything is ok.

I suppose its a hard problem because the ACT green led does not blink when lan cable is connected.


I’ve been trying to reproduce this and the only way I see this problem is if there is no firmware deployed to the board.

MFDeploy should tell you the firmware version number and assembly version numbers. Could you have a look to confirm this information please.

I think you can get this information by using the File->Connect to device menu item in MFDeploy.

The firmware update process is discussed on this page. If you plug the Netduino into the computer in DFU mode then the updater software should tell you the device type (Netduino 2 Plus).

If it says STM32 in DFU Mode then it would suggest to me that the firmware and device ID is missing altogether. It can be solved, let us know what you find.


Hi Mark,

I will try and keep you informed as soon as possible.

Thanks and best regards.


Hi everybody,

This is the information from MFDeploy:

HalSystemInfo.halVendorInfo: Netduino Plus 2 (v4.3.2.1) by Secret Labs LLC
HalSystemInfo.oemCode: 34
HalSystemInfo.modelCode: 177
HalSystemInfo.skuCode: 4102
HalSystemInfo.moduleSerialNumber: 00000000000000000000000000000000

SoftwareVersion.CompilerVersion: 410894

Using the updater software the Netduino appears as Netduino 2 Plus.

Using STDFUTester and DfuSeDemo to reinstall the firmare again does not work.

Using the update software also does not work.

How could I check a hardware problem?

So the firmware looks good.

I would try and deploy an application that connects to the network and starts to grab a web page.
