Netduino Plus 2 Firmware v4.3.0 (beta 1)

It seems i can't step through code line by line on 4.3, is that expected?

here are the errors i am getting:

Attaching to device...

Deployment error: failed to (re)connect debugger engine to debugging target.

The debugging target and the debugger engine failed to initialize because of unspecified device errors.

The debugger engine thread has terminated unexpectedly with error 'Debugger engine could not attach to debugging target.'.

hello i have a netduino plus, i can update my netduino plus with this firmware v4.3.0 (beta 1)

It seems i can't step through code line by line on 4.3, is that expected? here are the errors i am getting:

This firmware does not include: 1. Newest lwIP networking stack from .NET MF 4.3. This will be added in an upcoming release. do you have a date ? DPWS does not work

Hi Casmer,You should be able to step through code in 4.3. It looks like the debugger is just having troubles connecting. Which board are you using? What version of the SDK do you have installed? What version of firmware are you running on the board? Chris

I am was running 4.3 Beta 1 on the Netduion Plus 2 and I have the 4.3 SDK installed under visual studio 2012 Professional. I had 4.2 and 2010 installed and eventually switched back to it because every works fine that way. I uninstalled 4.2 before installing 4.3. I uninstalled both the net duino 4.2 and NETMF 4.2 frameworks before installing 4.3, though I don't know if the usb driver changed when i installed the netduino 4.3 sdk.

Could this also be the problem when the UI in VS2012Ultimate is extremely unresponsive during debugging? I'm using the 4.3 SDK/beta 1 firmware on a Plus2

Version: 4.3.0 Beta 1 (version 4.3.0.0 beta 1)

This firmware requires use of the .NET Micro Framework v4.3 SDK and Netduino 4.3.0.0 SDK.

To flash this firmware:
1. Detach your Netduino
2. Press and hold your Netduino's pushbutton while plugging it in via USB; this will put it in bootloader mode.
3. Erase the firmware on your Netduino using the STDFU Tester v3.0.1 application
> a. Select the "Protocol" tab
> b. Press the "Create from Map" button
> c. Select the "Erase" radio button option
> d. Press the "Go" button
> e. Wait for erase process to complete
4. Flash the attached .DFU file using the ST DfuSe Demonstrator v3.0.2 application (included with STDFU Tester)
> a. Locate the "Upgrade or Verify Action" pane (bottom-right pane)
> b. Press "Choose..." and select the attached DFU file
> c. Check the "Verify after download" option
> d. Press "Upgrade". It will take a few minutes to update your Netduino.
> e. Detach and reattach your Netduino (power cycle) or press "Leave DFU mode"

After flashing, to set your network settings using MFDeploy:
1. Select the Target > Configuration > Networking menu. Re-enter your IP address settings and MAC address.

Enjoy, and please let us know if you run into any troubles.

Hi just wanted to let you know that i was finally able to flash the Netduino 2 plus to the 4.3.0.0 beta 1

Im using windows 7 64 bits.

Problems i encountered:

-No detection in bootloader mode.

i upgraded to STDFU tester V3.0.3 same problem.

windows was able to recognise the usb device by going to the device manager and selecting the driver located in ..DfuSeDriver(manual update)

then i did flash but the program crashes when it does the verification(i tried several times to do the verify it doesn't do it)

But i verified the version within and it works!

Verified with the blink led program it works!!!

Just hope it will make it easier for someone else to upgrade it!

Thank you for the directions. I got a NP2 off the shelf and needed to reflash. Thank goodness playing with this is so rewarding

Is there any indication of when 4.3 final will be released?

Regards,

John.

I have notice that the stringbuilder after calling the clear() does not give the memory back to the memory pool.

Even in another thread when you dispose the thread the memory allocated by stringbuilder will not return after debug.GC(true).

Is there a beta 2 available, or soon to be?

Hi JoopC,That's really weird, good catch! Do you have a small single-threaded repro (disposing of the StringBuilder) where this happens? Or is it only when you call .Clear(), when you exit the background thread, etc.?

StringBuilder is managed code, so the latter case should be taken care of by the CLR automatically.

I have rewritten de programma code with the normal dim String and use the &= instead of .Append()

I do not have the time for the next 3 weeks.

But I have notice another strange dehavior in 4.3.

Purposely I made an error, for to show  ......... the Try() Catch() did not work.

When I am back I make a working example of stringbuilder memory. In the future when I find another stange behavior I will include an working example.

Hi all, this page http://netmf.codeple...ases/view/81000 states the 4.3 is in RTM release, does it mean that that's an out of beta release? Any news on ND+ / ND2+ 4.3 RTM release date?

Any news on the RTM of Netduino Plus firmware 4.3? It takes a lot of time!

Hi

I have some serious problems to deploy a hex file in to the Nd plus 2 with beta 4.3 firmware, i'm getting this error

and sometimes this

what did i do already?

uninstalled all Nf software and reinstalled

took 3 different usb cables

reflash the 4.3 beta firmware

what is possible?

to connect trough the F5 button and it says connected

get info from the netduino like firmware version and so on

network configuration

with 4.2 it is possible to load the hex file but getting a signing error (just info)

what is going wrong here? did almost everything now.

There are many, many complains about the very nasty/bad connection from the computer <->Netduino Generation2 when deploying program code to the Netduino.

Unintended Microsoft and Netduino get a bad name by the Tweakers with comments like bad investment and recommendations to buy a Arduino or Raspberry.

We are aware of the fact that the software update is a complex one but it is now 6 months after Microsoft releases the 4.3 and SecretLabs wraps herself in silence about any progress. 

Strange is also that the USB driver is from long ago:
