Hello,

I have buy a IFC6410 board to do some linux hacking.

I would like to run an up-to-date fedora on it in desktop mode.

For now I have a fedora 20 installed on a sdcard with freedreno.
But to boot it I launch a prebuild kernel from Linaro, it's a 3.4.x kernel.
I like to run an up-to-date kernel, If I can, perraps it's not possible.

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 :
  1. checkout on git the last stable kernel (3.16.1)
  2. do kernel config : make ARCH=arm qcom_defconfig (I'm not sure if I need to use qcom or msm defconfig).
  3. build kernel zImage and dtb with : make ARCH=arm CROSS_COMPILE=arm-none-eabi- scripts qcom-apq8064-ifc6410.dtb zImage
  4. Add qcom-apq8064-ifc6410.dtb to zImage : cat arch/arm/boot/zImage arch/arm/boot/dts/qcom-apq8064-ifc6410.dtb > zImage-ifc6410
  5. Extract bootimg.cfg and initrd.img from rob prebuild kernel (from freedreno wiki).
  6. Update bootimg.cfg cmd to replace ttyHSL0 with ttyMSM0. (
  7. Create boot img for fastboot with cmd : abootimg --create boot-ifc6410.img -f bootimg.cfg -k zImage-ifc6410 -r initrd.img
    The bootimg.cfg and initrd.img come from rob prebuild kernel (from kernel 3.4.x)
  8. Try to start boot img on the board with : sudo fastboot boot boot-ifc6410.img

And with this I have the following output on the serial console :

[25220] fastboot: download:01600000
[26630] fastboot: boot
[26670] Power on reason 32
[26670] cmdline: loglevel=10 msm.hang_debug=n earlyprintk=serial,ttyMSM0,115200,n8 console=ttyMSM0,115200,n8 console=tty0 root=/dev/mmcblk1p3 rootwait plymouth.ignore-serial-consoles rhgb androidboot.emmc=true androidboot.serialno=1515d75 androidboot.baseband=apq[26700] booting linux @ 0x80208000, ramdisk @ 0x82508000 (11679659)
[26700] Turn off LVDS PANEL.

And nothing more, while when I use prebuild boot img from rob or linaro, I have normal kernel output after.

Is there is something I did wrong, or I need to do in addition ?
In kernel_config_ifc6410 from linaro there as option : CONFIG_PHYS_OFFSET=0x80200000.
Is this option as something to do with the bootimg.cfg kerneladdr option ?

Because this option is not in my kernel build configuration.

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.
