Problem with Mountaineer Ethernet Mainboard

Archive

Hello. My mountaineer ethernet mainboard suddly stopped being recognized by Windows (I am running windows 7 pro). If I press the reset button, it appears in the devices and printer list for a few seconds, then disappears. I erased the firmware (using the pin1 to 8 on an extender), and was able to reload the firmware with DfuSe demo application. The application says that it successfully loaded the firmware. However, when I reset the mainboard. I does the same thing (shows in the devices and printers for a few seconds, and is gone). Any help would be appreciated.

Thank you.

I guessing power issues. Powered hub is my ever favorite.

I doubt it is a power issue, the board has worked fine for weeks. I have tried it on the PC USB ports, and a powered hub, with 2 different USB cables. Same issue. Any other ideas? Thank you.

Different USB cable? Different PC?
Just for testing purposes.

Different PC and different cable.

Very strange. Try loading the non Ethernet firmware. Works?

I loaded the Mountaineer_USB_PK42_QFE2.dfu instead of the ethernet version, and it works. Put the Mountaineer_Eth_PK42_QFE2.dfu firmware back on, and it fails.

@ rmurphy - Did you erase the whole memory and program zone before reinstalling the firmware ?

I had this kind of problem with the board when a program boots and loop in a throw exception constantly…Maybe a trace of a previous exectuable is left in memory…

Sorry, but Im new to this. Im not certain what you mean by erasing the whole memory and program zone. I did the connect pin 1 to 8 on the extender, and pressed the reset button. Then loaded the firmware.

@ rmurphy - Did you do that :

OK. I used MFDeploy to erase the firmware and deployment, and DfuSe to update the firmware (the ethernet version) and the board is working again. Thank you for all of your help.
