Topic: Davinci Jr Repetier Port
I figured this deserved a kick start. I'd like to see the community get together and get a working port of the Repetier firmware for the Davinci Jr (if possible). I wish I was savvy enough to do this on my own, however I am not.
Here's what I've gathered:
1) There is a working port of Repetier for the Davinci 1.0
2) The Davinci 1.0 uses a custom board driven by an Amtel microcontroller - the ATSAM3X8E
3) The ATSAM3X8E uses an ARM CPU - the Cortex-M3
4) The Arduino DUE is based on the ATSAM3X8E MCU
4) The Davinci Jr. uses a custom board driven by an Amtel microcontroller - the ATSAM4E8E
5) The ATSAM4E8E uses an ARM CPU - the Cortex-M4
6) The Cortex-M4 and Cortex-M3 share the same architecture and instruction set
7) There are some differences in the ATSAM3X8E and ATSAM4E8E MCUs. Here is a table of differences:
So, to those of you more knowledgeable than myself, here are my questions:
1) How feasible is porting the Repetier FW to the Jr?
2) How does the Jr using the ATSAM4E8E vs the ATSAM3X8E impact our ability to re-use the work done for the other Davinci models?
3) Assuming this is doable, what's our first step? A pin trace similar to that performed for the other Davinci models?
I appreciate any help on this. The folks over in the cartridge reset thread have been doing a fantastic job of whittling down the spool DRM. If we have that kind of support on the FW front I'm confident we can get a working port in no time.
