#24149 Reading SD card via USB - can you?

#23500 Status of Firmware confusing
Posted by bobk on 30 January 2012 - 02:36 PM in Beta Firmware and Drivers
I downloaded the 4.2 beta 3 again. I had the problem of the "no response". Since then, I have a new pc running windows 7 64. I do not know if anything changed from the Oct time frame as far as download version. I started with Sam-ba and reinstalled everything. I was able to go into Visual Studios 2010 and with a copy of the program that I found here in the forums, I was able to write to a 2gb sd card. Yeh. Now for some almost good news. I was not able to write to a 8gb sd card. I installed 4.1.1 B1 and everything worked including reading and writing to the 8 gb sd card. The same card will not work in 4.2 b3. I went back and forth between the different beta releases and the results were consistent.
Once the community tells us that the .NET MF 4.2 firmware is stable, we'll make it an official release and post it on the Downloads page... Right now, there are some core bugs to work out still. [We're checking in some new bug fixes today to see how they affect stability.]
Chris
Not sure if windows xp was the difference or the speed of the machine that would not allow 4.2 b3 to work properly, unless there was a newer version that I downloaded from the first post from this thread.
I did have one problem with 4.1.1 b1 with the reading of the 8 gd card initially. Netduino+ was plugged into a usb hub that was plugged into a powered usb hub. That caused my machine to crash. I could not get Netduino to be recognized until I re powered the usb hub. I will try this setup with 4.2 once I can get 4.2 version to read a 8 gb sd card.
Thanks for all the hard work.

#21775 GPS, GRPS and Google Latitude Tracking
Posted by bobk on 17 December 2011 - 12:10 AM in General Discussion
I also have been interested in GPS tracking. I want to put a tracker on my new motorcycle. One, for security if someone takes it. But I doubt that will happen. Two, when I go on a trip it is logged and if I need something people will know where to find me.
.
The most popular commercial products out there use GSM which probably the easiest and most effective way for a commercial product. However, being I am working on a DIY solution I am going to look at APRS. APRS is a data transfer system built on top of ham radio. That does mean I have to get a ham radio license. Check out aprs.fi to see if there is anyone using it near you.
Another option that I was thing about would be to use GPS and tie it into the ham radio APRS system using netduino. You would need a radio, but with many solutions out there already, it might not be feasable, but fun to do.

#20014 Problema after upgrade
Posted by bobk on 31 October 2011 - 02:20 PM in Beta Firmware and Drivers
One more thing to mention. My netduino and netduino_plus boards are stamped as at91sam7x512 and on the next line is has AU. In sam-ba there is no at91sam7x512-au in the list so I have been picking the -ek board type.Very interesting. Thanks for the additional info, Bob.

#19960 Problema after upgrade

Hi Bob,
Thank you for the additional testing.
Are you using the regular Netduino drivers or the new .NET MF 4.2 beta drivers?
http://forums.netdui...-net-mf-42-rc3/
If you switch does it make any difference?
Hoping this is a board-related (and not computer-related) issue so we can reproduce it here...
Chris
At one point, I went back to 4.1 of the netduino sdk, as a rollback. However, everything is now running on 4.2. I did not try loading the regular netduino bootloader onto the netduino plus using the 4.1 drivers. With the 4.2 drivers, the ping worked on the netduino plus board (and the blinking light under vb) using the regular netduino bootloader, but the ping failed when using the netduino plus boodloader on netduino plus.
With the regular netduino bootloader on the netduino plus board, visual studios showed the board conected via usb as Netduino_Netduino. So I would assume that the additional features of the netduino plus would not be available in visual studios.
Bob
Just to clarify, the bootloader versions were the ones loaded under the sam-ba app.

Hi Bob,
Trying to understand better here. In the text above, you mention that the pinging never comes back, but...
It appears that the pinging is working? If you pinged before flashing the ER_CONFIG/ER_FLASH firmware, it would say "Pinging... TinyBooter" instead.
Also, you appear to be using the Netduino firmware instead of the Netduino Plus firmware. Are you having beta upgrade issues on a regular Netduino?
Finally...when you updated, did you erase the board completely and flash the bootloader too? That is required for the .NET MF RC3 update.
Chris
I have not updated my plus yet. Wanted to try it on the regular Netduino first. I just plugged in the netduino-plus and the ping came back as:
Pinging... TinyCLR
The plus is still at the 2.1.0.6 level. I did have problems with the non plus one. When I first did the install (yes started with a clean install .. had to use sam-ba v2.9 to get the driver that would see the board connection as usb/... to work.) I did have problems and when I pinged I did get a not connected message or such. I did try a few times. with a few reboots in between.
As I mentioned before, it was getting the not connected message, but then after doing it a few more times, (a couple of times with the wrong board type in the sam-ba app), I rebooted the pc (windows xp) and did it again. If the ping is correct, then I guess that I do not have an issue at this time.
I will try this process again, using the netduino-plus. I will post here what results I get.
Thanks Chris for the reply.
