I have been asked to help with a project to build a device based on the Netduino framework and the STM32F405 family of processors.
We expect to use the same processor as the Plus 2, but leave off the ethernet hardware (we need the flash, not the ethernet) There is also a possibility of going to a larger package in the future to expose more peripherals; like a CAN bus.
I have two questions for anyone with experience building their own device.
1) For the first revision I would like to avoid having to recompile the ND firmware and just flash the current build to the new device. Is there any problem flashing the ND 4.2 build on a chip that has not implemented the ethernet hardware?
2) I would like to get a second set of eyes on the schematics before I build a prototype board. Is there someone interested in reading the schematic to catch my mistakes?
