Problem after attempt to flash firmware to 4.2

20 November 2014 - 06:20 PM

Hi Everyone,

 

We recently purchased a Netduino Plus which I assume is a Netduino 1 Plus. Everything was going fine until I wanted to use Regex to parse a small amount of JSON without running into memory issues. I read that Regex was available in .NETMF 4.2 and above. So, firmware update we shall proceed!

 

I downloaded the 4.2 update rather than skipping straight to 4.3 as I couldn't find anywhere if this was acceptable or not. Anyway, followed the procedure as described. Right near the end of the upgrade I got an error about not being able to apply the update. Apologies, I don't remember the exact wording.

 

I decided to try the 4.3 flash now as I didn't think it would hurt. This time though, I couldn't get anything to work. It seemed to be stuck in the bootloader. 

 

Eventually by reading the forum, I managed to download the 4.1.0.6 firmware which successfully applied. I decided to not worry about the 4.2 firmware and find another way to get the desired result from our JSON response.

 

However! Now when I deploy the app, I get this in the output windows:

 

Looking for a device on transport 'USB'
Starting device deployment...
Iteration 0
Iteration 1
Iteration 2
...
Iteration 59
 
Error 5 Device not found or cannot be opened - USB:Netduino
 
If I run MSDeploy (v4.3) I and ping I get:
 
Pinging... TinyCLR
 

And if I press device capabilities I get:

Can someone help me get my Netduino back to functioning either normally or with a 4.2 or 4.3 firmware whilst we're at it please? :) The device is literally useless in it's current state.
 
Thanks for reading.
 
Paul.  :)
 
PS I can't seem to make it go back into bootloader either to try and reflash to 4.2 or 4.3 right now.

Netduino + Wifi + Webapi

13 April 2014 - 08:52 PM

Hello everyone,

 

I've been asked by work to look into the possibilities of taking an input every 2 minutes or so from one of our machines and log that input into a cloud service sql database.

 

We have a webapi service that we can use to write to the database so no real db framework is needed as I believe there isn't any in the .net MF. Next I need to investigate the hardware. I've been reading the forum for the past couple of days and think I will be ok with the following:

 

Netduino 2: http://www.coolcompo...ment-board.html

Xbee Module: http://www.coolcompo...-series-zb.html

.Net Micro Framework by Stefan (thank you!): http://netmftoolbox.codeplex.com/

 

Can someone verify I'm heading down the right path? Is the Xbee ok with the Netduino 2 and the Framework? I'm really excited to be working on this project and I am really interested in what the Netduino could achieve for us!

 

Finally, with regards to the Xbee, initially db writes will be every 2 minutes but at a later date this may need to be as quick as every few seconds. Will this serial connection to the Xbee be up to the job on our quicker machines?

 

Thanks for you help in advance.

 

Paul.
