I am glad that you have chosen Cortex-M microcontrollers, and our [italic]NETMF for STM32[/italic] port as basis for your firmware. With it, we hoped to enable more hardware choices for NETMF projects, based on STM32. It is good to see the first fruits of this effort 8)
After a few other STM32F1 / STM32F2 / STM32F4 boards to which we adapted our port, such as ST’s [italic]STM32F4Discovery[/italic] kit, this gives us another hardware alternative for our (mainly) software engineering business.
I am particularly glad that your new products support both plain vanilla NETMF and also .NET Gadgeteer

PS
We plan to release the STM32F2 / STM32F4 variant of [italic]NETMF for STM32[/italic] in Q2 2012, again under the Apache 2.0 license.

Great! We have done plenty of work already so you can extend of what we have and gave back some too. This is a great example for everyone to see how open-source really works. Give some and get some, we all win. We will be cleaning up the code and uploading is ASAP.
Welcome to the community Cuno and we look forward to seeing more coding and more books
[quote]You will have to recompile as the chip on the Cerberus is 64 pin, and on the Discovery kit is a 100 pin chip…
If you don’t need the other pins then you might be able to get away with the binary image…[/quote]
That’s accurate as far as I understand it. The Cerberus FW would know how to talk to certain pins, the 100-pin variant has those same pins, plus more. It shouldn’t be a huge change to add the 100-pin variant’s pins to the Cerberus FW, and once that’s done, it could still be loaded on Cerberus (simply some pins wouldn’t have any effect).
Where do I file bugs for the MF porting environment?[/quote]
We do have native/beta forums which fit our needs best. Part of releasing the code is releasing plan so we all can work on it without adding extra unneeded work for maintenance. We also want to add as much as we can to simplify it for contributors to dig in.
Recently got a STM32F4_Discovery board to play with and just as I began thinking in the general direction of a NETMF port, I found the all new GHI Cerberus boards.
Ordered 2 x Cerb40 a couple of minutes ago, really like the formfactor!
I would love to see the Cerberus FW running on the STM32F4_Discovery as well…
As soon as the FW is available, it should be VERY easy to run on the Discovery board… should be able to flash the same file, in fact, if I understand the whole thing correctly.
Where do you see that? The two parts, STM32F405RG (Cerberus) and STM32F407VG (Discovery) share a datasheet: STM32F405xx/STM32F407xx and no mention is made of any differences in the clocks for the two.
