How to build new DTB

  • I want to be able to use a different CS pin for SPI9. For instance, if I wanted to make GPIO26 the CS for SPI9 instead. I see the DTS files in kernel/msm-3.18/arch/arm/boot/dts/qcom/msmcobalt-pinctrl.dtsi and others. How do I replace just the DTB on a VOXL unit? Or do I need to rebuild the whole kernel and replace the kernel as a whole?

    Hi @jrestifo ,

    Super late on this response. In general yes a kernel rebuild is needed. There's some gotchas so if you are proceeding down this path let us know.
