Hello I try to build the CAN driver for the WP76xx linus dist. I use the same guide line than the WP8548 (it work good with WP8548) but I meet a problem at this step I unzip the Legato dist in yocto folder and go inside run : export LEGATO\_BUILD=0 run : make image\_bin (finish sucessfull) run : . ./poky/oe-init-build-env I go to /yocto/build\_bin/ run : bitbake linux-yocto -c kernel\_configme -f I have this message : ERROR: Nothing PROVIDES 'linux-yocto’ ERROR: linux-yocto was skipped: incompatible with machine swi-mdm9x28 (not in COMPATIBLE\_MACHINE) ERROR: linux-yocto was skipped: incompatible with machine swi-mdm9x28 (not in COMPATIBLE\_MACHINE) ERROR: linux-yocto was skipped: incompatible with machine swi-mdm9x28 (not in COMPATIBLE\_MACHINE) Any idea ? For the WP8548 I have sucessfully build the linux dist with CAN support for MCP2515. It work good with IoT CAN board. Now I have a sample of WP7607-1 for test and my application use CAN bus. Thanks. Francis ---

It seems not so easy. I’m able to run menuconfig run : bitbake linux-quic -c menuconfig -f The CAN patch is not valide due to board file (9615 for wp8548 and 9607 for wp76). I have added USB SERIAL FDTI and rebuild the kernel. I will test it tommorow. For the CAN I have added the driver in the menuconfig and start to modify the board file. ---

Hay, did you made any progress? I am struggeling with the same problem. ---

@abrdsa: Did you see this snippet in the `mangOH.sdef`? ```auto // Uncomment to build for the CAN Bus IoT card on mangOH Red // #include "sinc/mangoh_red_can_iot_card.sinc" ``` It should be as simple as uncommenting that section and building the system. ---

Thanks for your help. I am using mangoh Green, not red, but that shouldn’t make a diference, should it? I am using the current mangoh VM and found a mangOH.sdef in /home/mangoh/mangOH. But this file does not include the section you descriped. I also saw that there is a can module in the /home/mangoh/mangOH/linux\_kernel\_modules. But anyway: doing it with mangoh is just a nice have. I Don’t want to use the legato framework and I want to be indepentent from a mangoh board. I want to add the kernel module during the yocto build. I managed to include the CAN Module in a yocto build using this [https://github.com/mangOH/mangOH/wiki/How-to-build-MCP2515-CAN-drivers-for-mangOH-for-mangOH-Green-slot-1](https://github.com/mangOH/mangOH/wiki/How-to-build-MCP2515-CAN-drivers-for-mangOH-for-mangOH-Green-slot-1) tutorial and modificated it. I can load the kernel modules but there is no can0 interface showing up. ---

Hello @Francis.duhaut, I had the same error as you did. Did you manage to fix it somehow? I was following [this guide](https://github.com/mangOH/mangOH/tree/master/experimental/waveshare_eink/linux_kernel_modules) by the way. Also, I don’t need to use CAN, but rather have framebuffer support (see [this thread](https://mangoh.discourse.group/t/adding-framebuffer-support/2571/2))
