USB connection don't work

Hi,

 

I bought a netduino few day's ago.

 

Today I plugged in a sd card and connect the netduino via usb to my computer.

 

I tried to deploy a Application via USB but I got everytime the error that the netduino couldn't found

 

In MF Deploy tool I get this error: Pinging... Error: No response from device

 

my netduino is visable in MFDeploy Tool as NetduinoPlus2_Netduino

 

I followed this instructions:

http://wiki.netduino...y.ashx?HL=reset

(After this steps my netduino isn't visable in MFDeploy Tool)

 

I Got also this error:

Translated from german to english

 

Power Surge on USB Hub:

Energy limit of a usb-hubs has been exceeded

 

 

here a example screenshot of the windows error from the web

Sorry for my bad english and Thanks for your held

 

kind regards

Hi Krone, That Wiki article appears to refer to the 1st generation Netduinos. The second-generation Netduinos will go into ST bootloader mode when you hold the button during powerup (which is how you flash them). Can you try erasing your Netduino Plus 2 and reflashing it using these instructions? http://forums.netdui...-v422-update-2/ Chris

hi Chris,

 

It doesn't work because the device field in STDFU Tester is empty and if I click GO nothing happend.

 

In my devicemanager my netduino is visable in bootloader mod as "STM32 BOOTLOADER" and in normal mod as "Netduino"

 

Marcel

any suggestions, what I should do?
