It's possible (3.16 kernel): http://snapshots.linaro.org/kernel-hwpack/linux-linaro-tracking-ll-ifc6410/49 > I have try to build kernel and create boot img for fastboot, but it's don't > work on my ifc6410. > > The step I do : > > checkout on git the last stable kernel (3.16.1) > do kernel config : make ARCH=arm qcom_defconfig (I'm not sure if I need to > use qcom or msm defconfig). > build kernel zImage and dtb with : make ARCH=arm > CROSS_COMPILE=arm-none-eabi- scripts qcom-apq8064-ifc6410.dtb zImage > Add qcom-apq8064-ifc6410.dtb to zImage : cat arch/arm/boot/zImage > arch/arm/boot/dts/qcom-apq8064-ifc6410.dtb > zImage-ifc6410 > Extract bootimg.cfg and initrd.img from rob prebuild kernel (from freedreno > wiki). > Update bootimg.cfg cmd to replace ttyHSL0 with ttyMSM0.

Changing the secondaddr to 0x82f00000 will fix the problem. > Thank you. > > PS: I'm not sure if I'm on the right mailing list, peraps send this on the > linux-arm and linux-arm-kernel mailing list would be more appropriate. or linaro-dev ml ;) > Doc I use : > > https://github.com/freedreno/freedreno/wiki/Fedora > https://wiki.linaro.org/Boards/IFC6410 > https://wiki.linaro.org/Boards/IFC6410/LinuxKernel > https://ci.linaro.org/view/lt-kernel-ci/job/LT-QCOM-working-tree/ > > > _______________________________________________ > arm mailing list > arm@xxxxxxxxxxxxxxxxxxxxxxx > https://admin.fedoraproject.org/mailman/listinfo/arm _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
