I am trying to build the imx realtime linux kernel for machine: imx6qsabresd.

bitbake -c compile linux-fslc-imx-rt. Getting compile errors related to gpu-viv. Please help!

Hi Oswald

official nxp bsp provides linux images as described in

attached Table 1. Freescale Yocto project images.

rt linux is provided by community, so one can post that on

meta-fsl-arm mailing list, so that someone familiar with it could try to assist you.

https://lists.yoctoproject.org/listinfo/meta-freescale

Differencies between nxp and community releases are described in

FSL Community BSP Release Notes 1.8 documentation

Best regards

igor
