#17432 Netduino Mini Firmware v4.2.0 RC1
Posted by Dixon on 02 September 2011 - 08:28 AM in Beta Firmware and Drivers
Notes on new SD card support
This firmware includes support for SD cards and System.IO filesystem support.
It includes two functions in the new SecretLabs.NETMF.IO namespace:
StorageDevice.MountSD(...);
StorageDevice.Unmount(...);
Both the MountSD(...) and Unmount(...) features are fully implemented.
You will need to manually add the SecretLabs.NETMF.IO assembly as a reference in your project to use the SD feature. You will also need to add the System.IO assembly.
Hi Chris, what is this new feature for? the previous firmware did not need to mount or unmount the SD in order to be able to use it. What's new now?
By the way, I always wanted to ask if all the writes to the SD are committed immediately or are buffered and lazily wrote in some way.

#13931 Netduino size. Where do I find this in Visual Studio?
Posted by Dixon on 03 June 2011 - 08:13 AM in Netduino 2 (and Netduino 1)
There is SolutionWizard application in the .NET Micro Framework Porting Kit to select modules/features you want to be included in the firmware. Regarding the firmware size and memory organization, please refer to "Laying Out Memory on .NET Micro Framework Devices" topic in the Porting Kit documentation, which describes it in great detail.
Hi CW2,
Thanks a lot for your answer, everything is clearer now.
#13847 Netduino size. Where do I find this in Visual Studio?
Posted by Dixon on 01 June 2011 - 06:30 AM in Netduino 2 (and Netduino 1)
Removing USB is pretty easy (and in fact, you can just copy most of the changes from the Netduino Mini BSP to the Netduino BSP and recompile).
But how? how do you control what parts of .NET MF are included and what parts not, and how do you know how big is the .NET MF being loaded (i.e. total size - fre size - our app size)
In theory .NET Framework requires 256MB of RAM, what is much more than the actual Netduino RAM size. It seems it's because the loaded .NET MF is stripped down, removing WPF support among other things. How can we know what it is included and what not?
#20683 Automatic Recovery
Posted by Dixon on 16 November 2011 - 07:34 AM in Netduino Plus 2 (and Netduino Plus 1)
We could also add a Reset feature to a future firmware release. The function is already built into the firmware...we'd just have to create a wrapper for it. You could also create one and build it into your own custom firmware.
The firmware could also be tweaked to activate the hardware reset function in case an exception occurred. Lots of options.
Hi Chris,
Did you manage to include the Reset function within the firmware? if not, how can we tweak it to activate the reset without need to use a GPIO?
Can the firmware be tweaked to just reset the TCP/IP stack?
#20492 Ethernet stop working after around 20-60 minutes running
Posted by Dixon on 11 November 2011 - 07:58 PM in Netduino Plus 2 (and Netduino Plus 1)
I can confirm this bug.
Netduino will stay up for days on a quiet, local LAN. If I take it and plug it into our university's LAN, it freezes within minutes. The board remains responsive to input pin events, but the network connectivity no longer works until you press the reset button.
It seems the Netduino's stack can't handle tons of broadcast traffic created by management services on large lans. (Cisco proprietary, or STP, etc.)
Exact same behavior in my university, after few seconds of our typical 30-45KB/s background broadcast noise, while it worked fine for weeks at home with low traffic.
A potentials work around would be to put a cheap nat router between the netduino and lan, and port forward 80 on the wan side ip to the netduino. That should block all of the broadcast noise, but let in the http requests.
But this kill the beauty of a tiny electronic to connect something to internet. If an additional router was requited, then is better and far cheaper to buy an OpenWRT compliant router such as Linksys 54G for 60€ and program it in C
I would be just happy if it would be a way to reset the eth interface when N+ detect lose of network connectivity

#14271 Netduino send ICMP Ping ?
Posted by Dixon on 13 June 2011 - 08:07 AM in Netduino Plus 2 (and Netduino Plus 1)
Did you ever work this out?
I'm thinking to ping my gateway to determine if my network on the netduino has died, or if the internet is down. If the network on the Netduino is to blame, I have to request a reboot. But I can't have the Netduino rebooting every minute while the internet is down.
How do you reboot the netduino by code?
