You're quite welcome

LED near D7 flashing very very fast and kind of dim

That's normal with the latest firmware: it indicates that SPI communication is indeed taking place.

Please contact at fabien <at> nwazet <dot> com tomorrow so that we can figure out what's going on here.

Thanks,
-Fabien.

Let's wait until you have the UART diagnostics up for a complete picture. Thanks, -Fabien.

Sounds good. Can you please provide a stack trace when you encounter the exception as well as a dump of the BasicTypeDeSerializerContext._buffer? Thanks, -Fabien.

Ok. When you get to testing the UART, can you please enable the DAQ's internal diagnostics and post the output that you see in your dumb terminal when mounting the file system?
See http://nwazet.com/co...torageRegisters for enabling diagnostic messages.

Thanks,
-Fabien.

Yet, you're able to use all the other functions of the DAQ, except for the file system?

Are you using the latest C# driver from https://bitbucket.or...royer/nwazet.go?
Can you please post the code you're using here so that I can test it and try to repro what you're seeing?

#38395 Nwazet SD Card

Posted by Fabien Royer on 02 November 2012 - 11:23 PM in Netduino Go

Thanks. That tells me that you have the latest version of the DAQ firmware running, which is good. Now, if you use the exact file system test sample posted on our site (adapted to the actual Go socket you're using), what happens?

#38392 Nwazet SD Card

Posted by Fabien Royer on 02 November 2012 - 09:05 PM in Netduino Go

That's not likely. Let me ask you this: does the LED next to port D7 blink when there's communication between the Go board and the DAQ?

Hi there,

The call to "sd.Initialize(GoSockets.Socket5, "SD")" is incorrect, so it makes sense that nothing's working

Have you looked at the tutorials on the DAQ product page? If not, check out this one which shows how to initialize the DAQ and how to use the file system: http://nwazet.com/co...Q/10-FileSystem

Cheers,
-Fabien.

#38360 Nwazet Go Pro Kit

Posted by Fabien Royer on 01 November 2012 - 11:32 PM in Netduino Go

Hi Mattster, Thanks for the feedback and I'm glad you like the kit

About the knob: a good way to ensure that the knob doesn't wobble is to let it rest flat on the top board before securing it to the shaft. Then, as you tighten the screw against the pot's shaft, gently push down on the dome of the knob. That method has worked well for me so far, but a bit of tape works too. Cheers, -Fabien.

Chris, I didn't keep that flashing application because it didn't work but you can repro the failure yourself using the binaries from our source repository as discussed at the beginning of this thread. The length of the cable (5 or 10cm) does not affect the outcome. Btw, it might be good to split this thread at the point where it started straying from the topic. Thank you, -Fabien.

Hi Chris, Have you tried flashing our Nwazet DAQ module as well? This is what Jason was looking for in this case. When I did, the flashing application just got stuck on the last page indefinitely. I have personally given up on trying to flash firmware from a Go! main board because it's unreliable: one module might work 5 times in a row and fail on the 6th attempt, or based binary size changes, it may or may not work. IMO, Go! users should not have to go through so much pain and frustration to get upgrades: it should be a smooth user experience, baked into the Netduino Go! firmware by design. -Fabien.

#37798 Nwazet Go Pro Kit

Looking good like the rest of the Nwazet kit. Would be nice to see an EU distributor.
Regards,
Mark

Hi Mark,

We looked for EU distributors early on when we launched our Go! modules. Unfortunately, UK distributors who have responded so far wanted a very high cut for their services, to the extent where it was not sustainable for us. Outside of the UK, I would recommend checking out http://shop.microfra...gue.aspx/nwazet who resells Nwazet products in the EU and asking them for the Nwazet Go Pro kit.

I hope this helps.

Cheers,
-Fabien.

We all wish flashing modules through a Netduino Go! worked well w/o jumping through hoops, but it's just not the case. I am as bothered as you are that this situation has not yet been addressed for all Go! users in a way that is seamlessly integrated with the Go! platform and this is why I proposed an alternative and spent time making a video to show how it works. Yes, there is a bit of hardware needed, but it's common and cheap.

#37049 Flashing Go Modules using ST Microelectronics’ Flash Loader Demonstrator

Posted by Fabien Royer on 11 October 2012 - 06:29 PM in Netduino Go

About flashing the STM8S serially: this document by ST describes in details the STM8 bootloader and which STM8S versions feature a bootloader: http://www.st.com/in.../CD00201192.pdf This may be helpful for anyone considering building modules based on the STM8S and would like to ensure that they are easily field-upgradable. For versions that do not have an embedded bootloader, it is possible to add one in software and there are reference implementations provided by ST to do so. Cheers, -Fabien.

#37042 Flashing Go Modules using ST Microelectronics’ Flash Loader Demonstrator

Posted by Fabien Royer on 11 October 2012 - 05:07 PM in Netduino Go

Thanks Stan, You're correct: there must be a bootloader on the chip. Not all versions of the STM8S have a UART bootloader unfortunately, and those require SWIM programming. All ARM Cortex M chips do have one. Cheers, -Fabien.

#36991 Flashing Go Modules using ST Microelectronics’ Flash Loader Demonstrator

Posted by Fabien Royer on 10 October 2012 - 10:32 PM in Netduino Go

In this video, I demonstrate how to build a simple breakout board to connect a Go! module to an FTDI ‘USB to Serial’ breakout board for the purpose of updating the module’s firmware. The application used to download the firmware to the module is provided by ST Microelectronics. This method has been tested with ARM Cortex Mx and STM8S chips and works very reliably.

#36913 Nwazet Go Pro Kit

What were you thinking guys?

The heavy metal knob introduces a bit of inertia and provides a great natural 'force feedback' to the user, which translates into a much finer control on the input.

So, what were we thinking?
We were thinking about building a quality piece, paying attention to all details, big and small

Cheers,
-Fabien.

I won't be able to confirm until I can test with the actual SL Ethernet module.
All I can say is that I just took a look with another SPI Ethernet module (http://www.futurlec...._Ethernet.shtml) and it fits between the two acrylic plates.

The plates in the picture were the 'prototype' ones. The actual production plates have minimalist laser-etched markers to let you know where to connect things

Also, the final plates don't have any holes on the top plate, above the power supply.

Matt, Thanks for sharing this. I love what you put together for your drivers and that would be perfect. Steve, Thank you for your offer! That would be awesome and sincerely appreciated! -Fabien.

Hi,

I added an archive containing all the Nwazet Debug and Release assemblies needed to build projects without the source code: https://bitbucket.or...tAssemblies.zip

I don't have the time to build a nice installer for these assemblies but if someone would like to contribute that piece, that would be greatly appreciated
