Hi Chris, How to get the fx30 yocto source code by leaf? Here is what i got from swi-fx30-catm\_1.0.0 identifier: owner@ubuntu:~/leaf/leaf-data/wp77$ ls fx30-catm-image fx30-catm-linux-image swi-vscode-support fx30-catm-legato swi-fx30-catm wp77-modem-image fx30-catm-legato-image swi-legato wp77-toolchain ---

Hi @jyijyi, Just execute this command: leaf getsrc swi-linux Leaf will pull the entire yocto workspace using repo. You’ll need to setup SSH keys on [gerrit.legato.io](http://gerrit.legato.io) The R11 source will be available with identifier: swi-fx30-catm\_2.0.0 BR, Chris ---

Hi Chris, it seems I will need to rebuild the image of my fx30 to implement the CAN drivers and also to update the GLIBC of my target device. I am trying to download the source from gerrit but it seems it fails due to public-key ack: **XXXXX@XXXXX.com.au@gerrit.legato.io: Permission denied (publickey).** **fatal: Could not read from remote repository.** How do I implement the ssh publickey? Do I need to generate one on gerrit and to store it locally to my machine (~/.ssh) or the other way around? Because on gerrit I can`t do either things… ---

Hi Claudio, You’ll need to register at [gerrit.legato.io](http://gerrit.legato.io) and then add your public key under your profile settings. You can generate a private/public key pair using ssh-keygen. BR, Chris ---

Hi @cchenry , I have the same issue and get stuck. Can you help to give us a step by step on how to pass through those pubic key problem? I have tried ssh-keygen -t rsa -b 2048 -C “[xxx@xxxxxx.com](mailto:xxx@xxxxxx.com)” and then " cat /home/owner/.ssh/id\_rsa.pub " copy the value to “[https://gerrit.legato.io/settings/#SSHKeys](https://gerrit.legato.io/settings/#SSHKeys)” Still I saw the following: * * * Proceed? (Y/n) Y Checking credentials… Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. ERROR: Something went wrong when trying to connect to ssh://xxx@xxxxxx.com@gerrit.legato.io:29418/manifest * * * ---

Hi @cchenry, Thanks for your help. Finally I can download the source code by the steps below: 1. ssh-keygen -t rsa -b 2048 -C “[xxx@xxx.com](mailto:xxx@xxx.com)” 2. cat /home/owner/.ssh/id\_rsa.pub 3. copy the value to “[https://gerrit.legato.io/settings/#SSHKeys](https://gerrit.legato.io/settings/#SSHKeys)” set the username to “xxx” in [https://gerrit.legato.io/settings/#Profile](https://gerrit.legato.io/settings/#Profile) ( this can only set once) 4. sudo chmod 400 /home/owner/.ssh/id\_rsa 5. ssh-add /home/owner/.ssh/id\_rsa Enter passphrase for /home/owner/.ssh/id\_rsa: 6. sudo chmod 700 ~/.ssh/ sudo chmod 600 ~/.ssh/\* sudo chown -R owner ~/.ssh/ sudo chgrp -R owner ~/.ssh/ (where owner is the user name of my PC) 1. in VScode, choose the profile you needed: leaf shell leaf env user --set GERRIT\_USER=“xxx” leaf getsrc swi-linux ---

I have setup the leaf with the latest release for the FX30S, is there any different way to build an open the CAN interface on the target from what I have done earlier? I have, once again, compile my project and deployed to the target and then run the start.can.sh script, still get an error from the kernel when trying to load the can driver: root@fx30s:~# ./start\_can.sh “./start\_can.sh board [slot]” where board is “green” or “red” or “yellow” and slot is “0” or “1” root@fx30s:~# ./start\_can.sh red 0 Unload of module can\_iot.ko has been successful.

Hi Claudio, Could you please explain how you built your can\_iot kernel object? Your log doesn’t show a magic number issue, but I wonder if you’ve built it separately from the kernel. Are you using the prebuilt R11.0.0.007 kernel image? Could you please try pulling the yocto source code: leaf getsrc swi-linux Add your kernel driver to the yocto kernel. You may also need to enable the CAN options as well. Then you can build the full image including the kernel: cd swi-linux make The resulting image will be in: build\_bin/images/public Alternately, the Legato framework supports installing a kernel object via a Legato application. I’m not familiar with the exact process, but there should be documentation on [legato.io](http://legato.io) BR, Chris ---

@cchenry, I am actually using the legato framework for that, the only reference I have found was this: > **[Running the MCP2515 CAN driver for mangOH Red · mangOH/mangOH Wiki](https://github.com/mangOH/mangOH/wiki/Running-the-MCP2515-CAN-driver-for-mangOH-Red)** > > Primary mangOH git repository. Contribute to mangOH/mangOH development by creating an account on GitHub. …the system definition link is broken. The system definition I am using is this one: #include “$LEGATO\_ROOT/default.sdef” apps: { } appSearch: { } interfaceSearch: { } moduleSearch: { /home/claudio/legatoWorkspace/legatoAF/drivers/mangoh/can\_common /home/claudio/legatoWorkspace/legatoAF/drivers/mangoh/can\_9x07 } kernelModules: { mcp251x.mdef can\_iot.mdef } This compiles fine and I can download to the target, then I locally run the start.sh script (assuming the target is for RED as the wp77 - FX30 should be)… root@fx30s:~# ./start\_can.sh red 0 Unload of module can\_iot.ko has been successful. sh: write error: Device or resource busy Could not load the required module, can\_iot.ko.

We have started with the package and were told to wait for the new release as the _The stock WP77 code will run on an FX30 but peripheral functions won’t work._ Now I see that I am working on leaf shell, you are working on VScode and cchenry is talking about toolchain and system rebuild. I did actually try with exact the same system definition and using the swi-fx30-catm\_1.0.0, which didn`t work. Is the CAN drive enabled on the R11 and how do I get it operational…? _If you’re able to wait another week or 2, the R11 release is just about ready._ ---
