Linux DTB compilation failed - imx6ull

pankajjoshi — Thu, 12 Sep 2019 12:40:25 GMT

While I do the Linux build using Yocto for imx6ull, I get the following error while Device Tree is built.

Error: /home/lem/kernel_silex_migration/tb-lem-release/linux-fslc/arch/arm/boot/dts/mackinac.dts:477.1-13 Label or path iomuxc_snvs not found
| FATAL ERROR: Syntax error parsing input tree

However the same Label is present in old Linux kernel and building fine. Is it because of DTC version? Any pointer is helpful.

Hi pankajjoshi ,

Please follow "i.MX Yocto Project User's Guide" to compile various components. To compile device tree for linux you can use below two commands:

bitbake -c compile linux-imx -f
bitbake -c deploy linux-imx

Please download the "i.MX Yocto Project User's Guide" from this link.

Regards,

Kunal

Hello Pankaj Joshi,

Did Kunal’s suggestions worked? These are a good starting point if you are not making changes to the BSP Release.

If you are porting or editing the device tree it would be good to make sure that the required files can be located, for example in this case the iomux_snvs include.

Regards,
