Hi all, I am trying to setup the CAN iot card from talon into the FX30 image. For this purpose I have just created a system which includes the kernel module which was found in this repo: > **[mangOH/linux\_kernel\_modules at master · mangOH/mangOH](https://github.com/mangOH/mangOH/tree/master/linux_kernel_modules)** > > master/linux\_kernel\_modules moduleSearch: { $LEGATO\_ROOT/drivers/mangoh/can\_common } kernelModules: { can\_iot.mdef } I can compile the system and to deploy to the target, but once I runt he start\_can.sh I get the error: Unload of module can\_iot.ko has been successful. sh: write error: Device or resource busy Aug 19 01:30:13 fx30s user.info Legato: INFO | supervisor[895]/supervisor T=main | kernelModules.c le\_kernelModule\_Unload() 1784 | Requested to unload module ‘can\_iot.ko’.

did you use the correct toolchain for the compilation? Seems the version check has problem: Aug 19 01:30:14 fx30s user.err kernel: [1023.175549] can\_iot: version magic '3.18.140 preempt mod\_unload ARMv7 p2v8 ’ should be '3.18.44 preempt mod\_unload ARMv7 p2v8 ’ ---

maybe it is not for FX30S. The latest FW for FX30S is R9. ---

do you have a link to that FW? Because this is the latest toolchain for 64bits I have found online… ---

No, I don’t have as the latest package from LEAF is for the R9 FW (FX30catM) [https://source.sierrawireless.com/resources/airlink/software\_downloads/fx30-firmware/fx30-firmware-catm/#sthash.PzmOrYM1.dpbs](https://source.sierrawireless.com/resources/airlink/software_downloads/fx30-firmware/fx30-firmware-catm/#sthash.PzmOrYM1.dpbs) ---

Ok, so this is a problem with the toolchain not matching the latest firmware revision? How do I solve this? ---

I don’t know if this is the root cause, but you can downgrade your module to the official one and use the toolchain in LEAF. ---

ok, I have actually manually installed my dev environment, have also installed leaf but I am working within the legato workspace and suing the “source bin./configlegatoenv”. Leaf is installed but I am not running the leaf init… So… using the toolchain for the wp77xx: ( **FX30 and FX30S CatM** ) [wp77xx] Toolchain dir = /opt/swi/SWI9X06Y\_02.32.02.00/sysroots/x86\_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi which firmware should I downgrade to? If I ssh into the FX30S and run the `cm info all` I see this is the firmware actually loaded into the target: Firmware Version: SWI9X06Y\_02.32.02.00 c2e98c jenkins 2019/08/30 07:28:21\* which should match with the toolchain I am using, right? ---

according to “leaf search”, the latest one is “swi-fx30-catm\_1.0.0” ---

oh, I understand but I am not currently using leaf… So my question is, if I am using the right toolchain and this matches the firmware in the target, this should not be a problem, correct? I can start using leaf, that is not a problem, but I would rather get the the bottom of this problem first as this is only one part of the application and I am working on something else as well… So I can save some time. ---

as said before, I don’t know if this is the root cause, but worth to give a try to match the version check. ---

if you are going to use WP77 FW instead of official FX30 FW R9.1, then you can treat it as a WP77 module ---

I am lost… 🙂 and I need to understand what I am doing… So the whole reason to use leaf is to work outside of the legatoworkspace and still to have access to the CLI commands. If I am using leaf, is the compiler still using the same toolchain? leaf status ┌─────────────────────────────────────────────────────────────────────────────────────────┐ │ Workspace: /\*\*\*\*\*/mySystemAws │ ╞═════════════════════════════════════════════════════════════════════════════════════════╡ │ Profile: FX30stable [current] (sync) │ ├──────────┬─────────────────────┬────────────────────────────────────────────────────────┤ │ Packages │ Identifier │ Description │ ├──────────┼─────────────────────┼────────────────────────────────────────────────────────┤ │ Included │ swi-fx30-catm\_1.0.0 │ SDK for FX30-CATM (Release 9.1.1.013 + Legato 18.06.1) │ I have run the mksys and then uploaded the files to the target, still same result when I run the start\_can.sh ---

you can install the toolchain which is in this path owner@ubuntu:~/leaf/leaf-data/wp77$ ls /home/owner/leaf/leaf-data/wp77/wp77-toolchain environment-setup-armv7a-neon-poky-linux-gnueabi manifest.json site-config-armv7a-neon-poky-linux-gnueabi sysroots toolChainExtractor.sh version-armv7a-neon-poky-linux-gnueabi And the usual legato framework will be in this path: /home/owner/leaf/leaf-data/wp77/fx30-catm-legato So now you have the toolchain, legato framework, and your mangoh source for your compilation. ---

Hi there, You need to build the kernel and the module using the same toolchain. The simplest is to rebuild the FX30 yocto image with canbus enabled. To do this pull the swi-fx30-catm\_1.0.0 leaf identifier to get the R9.1 source code. The stock WP77 code will run on an FX30 but peripheral functions won’t work. If you’re able to wait another week or 2, the R11 release is just about ready. BR, Chris [Next page](https://forum.legato.io/t/fx30-with-wp77xx-with-talon-mangoh-can-interface/5362.md?page=2)
