In Topic: MFUpdate supported on 4.3?

22 January 2014 - 04:18 PM

We'll be updating the Netduino 4.3 beta firmware soon...and we're getting fairly close to an RTM release). We'll post all the source code for it.

Thanks. Anxiously waiting  :)

your Netduino doesn't have room for MFUpdate partitions.

Could this be done with external storage (SD) ?

If so, is it possible to get access to the 4.3 firmware source code ? I'd like to get a chance at implementing that...

I'll try that and report to the forum if/when I've made progress.

Hello, Chris,


where can I find the information about the flash, its layout, how it is programmed, the format of the file used to program it, etc... Would you have any sample code ?

That sounds intriguing, but I'm not sure about the [font="calibri, sans-serif;"]feasibility[/font]. As I understand it (and I'm by no means an expert), the app on the Netduino flash creates the assembly and method objects when loading a program from the SD card, so they are part of the flash application's RAM. So if the flash application exited (which is probably necessary to write to the flash memory), it would dispose of the assembly and method objects as well. I'm also not sure if the firmware would allow for direct access to the flash memory from managed code, though it may be possible to modify the firmware to allow this.

The point is that the flash application wouldn't need to exit. The loader would just hard reboot the system. And the loader might have to be partially unmanaged.

Any body has any idea what the flash layout is, where to put the application assemblies and how to burn the thing ? or should I reverse engineer the firmware and/or bootloader ?
