@dc42
Thank you very much to take the time to write the reply.

@dc42 said in Run latest version on ATSAME70Q21:

Code compiled for the SAME70Q20B will run on the SAME70Q21B

That's a great news!

@dc42 said in Run latest version on ATSAME70Q21:

If you do intend to use that additional 1Mbyte, then you will at least have to change the linker script

I expected this, but that can wait for now. My goal for now is running the latest stable release on a custom board that I am in the process of building it right now.

@dc42 said in Run latest version on ATSAME70Q21:

If you need to enable in-app programming of the flash memory

Does the "in-app programming" required for anything related to the workflow of RRF?, or you are talking about flashing the firmware using in-app programming method?(I am a bit confused!)

But anyway, I think I tried this approach awhile ago by swapping all "SAME70Q20B" by 'SAME70Q21B" but failed to at linking stage but I will give a try later again.

I am software developer but unfortunately my experience with c++ and using eclipse is somehow limited (I am a Web developer) but I think I can manage to make the changes(it will be a good excuse to learn new things about eclipse anyway since I am a Visual studio guy)

Thanks again for your reply.

After making some research about what this NT stand for, I found that it is used for connecting two different nets to each other like analog ground and digital ground and since I am using Eagle, I wasn't able to understand what on earth this connection for(eagle does not have this specific Net tie thing)

I was confusing since in the SAM E70 Xplained dev board there wasn't anything like that but later when I went through the Duet3 Schematic I found they want to use the ref ground for specific tasks!

Anyway, releasing all the CAD file or at least the PCB layers in PDF format will be very nice to help people like me making their own custom board faster!

It seems you guys are busy those days, hope someone will be able to help soon!

I want to create a custom board for RRF3 and going to use the mentioned MCU(ATSAME70Q21) so, some help would be very nice
thanks!

They can at least release PDF version of the PCB since there are some places in the schematic that I do not know what they represent exactly, like for example the point that VREFN connects to GND is through something called NT1,2 and because of that, there is a different between using GND and VREFN even they are both being connected at the end to the same point!

I wanted to edit my original post to clarify that I was taking about ATSAME70Q21 & ATSAME70Q20 when I did the parametric search
but the system stopped me from submitting the edit and it said only allowed within the first 3600 seconds!

I was able to run the RRF version(Release 3.1.1) on SAM E70 Xplained board and I was able to connect to the board with the native USB and also using the on-board Ethernet port using the Duet Web Control.
Of course there was some error messages but never the less, it worked!

I did a parametric search and compared both of them and it seems the only apparent difference is the amount of the program memory!

My question now, this version is compiled to run on ATSAME70Q20 so what should be changed in the compilation and the source code to be 100% compatible with Q21?
Or this is not required and everything with be just fine?

Thanks

After some investigation and reviewing the schematics of the xplained and Duet3 I found that I can use the other USB port on the Xplained the same way used on Duet3 and I was able to use YAT according to this page:
https://duet3d.dozuki.com/Guide/1.)+Getting+Connected+to+your+Duet/7

That being said, I couldn't really get it to connect via the web interface!

I did exactly what came in Step 8:
Duet 2 Ethernet/Maestro and Duet 3 standalone - Enable Ethernet Connection

I entered M552 S1 P192.168.1.110 and I got this message:
ok<LF>Ethernet running, IP address = 192.168.1.110<LF>

but this is not showing on the my ip list in my router nor I can connect via Duet web Control !!

I have been able to finally build a version with SAME70XPLD build configuration and I was able to download the bin file on the board using Atmel studio 7, I made sure that the boot is from the internal flash and the programming address is 0x400000 (default)

After connecting the board with an Ethernet cable I tried to find an IP address for the board but I couldn't find any!

Can someone help here?

I was hoping to connect to the board with Duet web control after this long journey!

BTW, Atmel Studio identify the onboard chip as ATSAME21Q70B not A
Thanks

Thanks for reply, I really was planning to design my own board based on the Duet3 hardware but with different philosophy in mind, I want to adopt most of the hardware but on an industrial scale.
With I/O protection and with higher operating voltages 36~48V for steppers, an isolated power supply rails for logic and control/drivers.

I am going to use the same microcontroller (ATSAME70Q21) and I am going to use most of the current pin configuration used in Duet3.

I will try to see the branch you referred to but I really doubt that I will be able to make a good use of it, I am not used to develop in eclipse nor have a big experience developing with c/c++ but I will try my best
thanks.

I was wondering if it is possible to install the Reprap firmware on SAM E70 Xplained kit ?
A quick review for the schematics of the duet3 and the kit revels that they both are using the same KSZ8081RNACA chip with the same bin configuration!
I mentioned the Ethernet part because I think it is the most important part for communication with the firmware after installing it on the Kit!

Can I use the current compiled firmware from Github or should I compile my own ?
I have tried to compile my own but I faced a lot of issues!
