Quick update: I just posted an update to the NetduinoGo.ShieldBase.dll driver for Shield Base. This will enable the reset pin on Shield Base. After the update, driving the /reset pin low on Shield Base will reboot the Netduino Go mainboard. It is not necessary to upgrade the firmware on Shield Base to take advantage of this new feature. The attachment is in the second post of the current thread: http://forums.netdui...dpost__p__36829 Chris

I just tried using the Shieldbase updater after upgrading my Go to the 4.2.1.0 firmware. I also made sure to update the .Net Micro framework and the Netduino SDK.

It fails with "An unhandled exception of type 'System.Exception' occurred in Microsoft.SPOT.Hardware.dll" message.

The line of code it stopped on was:

_socketLeds[0] = new OutputPort((Cpu.Pin)0x16, false);

This was in STM32Bootloader.cs

So at this point I cannot update my 2 Shieldbases...how do we fix this?

Hi Greg, We'll need to update the reflash app for the latest Netduino Go firmware. It will take a day or three; we're working on it... Chris

Just updated the GO to 4.2.1.0 and that appeared to go well.

Next step to update the Shieldbase and at this point things did not go too well. Compiled and deployed the application to the GO with the Shieldbase on port 5. Hit the button when prompted and hit a System.Exception on the line:

_socketLeds[0] = new OutputPort((Cpu.Pin)0x16, false);

Line 96 of STM32Bootloader.cs.

Wondered if it might be a reference problem so I removed the GoBus reference and added the one in the 4.2.1 firmware and still have the same problem.

Any thoughts?

Mark


Just noticed someone has the same problem and Secret Labs are working on it.

Hey guys, if you're having the error that we've been waiting to fix, then you probably followed the instructions and upgraded the firmware on your mainboard first. It probably means you're running 4.2.1.0, which doesn't work with this shield base upgrade. So go here: http://forums.netdui...?showtopic=5916 Download 4.2.0.2 for your mainboard and reflash it back to the old firmware. Then upgrade your shield. Verified it works right now. Will verify if I can successfully upgrade the mainboard BACK to 4.2.1.0 after the shield base is done.

Has anyone experienced, that their analog readings are wrong? Measured directly on the sensor, i get a value of 0.47v but Shieldbase reads 0.14v... it seems to be dividing the actual value with the voltage...

Nicky which method are you using .Read or .ReadRaw? The .Read gives you a float value 0 to 1.0 the .ReadRaw gives you an integer that reads 0 to 4095.

Oh ffs... so that means, that I always will have to multiply the returned value with the voltage? Sigh, these electronics are killing me! Thanks mate.

How many base shield can I connect to a netduinogo?

How many base shield can I connect to a netduinogo?

As of now, only 1.  In the future up to 8 without any hubs, and who knows with hubs.

Quick note: we have updated the Shield Base reflashing app to work with the latest Netduino Go firmware. We're also working on beta 5 firmware for the shield base, so we'll have even more updates soon. Chris

That's awesome news Chris!
