Inforce 6410 Plus
- prebuilt kernel: ifc6410-boot-f20.img
- kernel-msm branch: ifc6410-drm
- defconfig: ifc6410_rob_defconfig
- if android still running:
sudo adb reboot-bootloader
- once board is booted to fastboot, if you want to prevent android from booting automatically:
sudo fastboot erase boot
- alternatively, see forcing Inforce 6410 Plus into fastboot
- boot linux:
sudo fastboot boot ifc6410-boot-f20.img
note that you can override the kernel commandline with fastboot, for example to boot with filesystem on sd-card:
sudo fastboot -c "console=ttyHSL0,115200,n8 console=/dev/console lpj=67677 root=/dev/mmcblk1p3" boot ifc6410-boot-f20.img
Resizing boot partition
To boot from eMMC (without fastboot), a larger boot partition is needed. The following might work on other devices/boards too, but be very careful to check the partition #'s, and that there is nothing important in the partitions following the boot partition. On the ifc6410 the boot partition is
mmcblk0p7. The following will wipe out the android userspace partitions.
sgdisk -d 7 /dev/mmcblk0 sgdisk -n 7:393216:524287 /dev/mmcblk0 sgdisk -c 7:boot /dev/mmcblk0 sgdisk -A 7:set:60 /dev/mmcblk0 sgdisk -t 7:ea00 /dev/mmcblk0
after resizing mmcblk0p7 you can
fastboot flash boot ifc6410-boot-f20.img
making a serial cable:
The debug UART (
console=ttyHSL0,115200,n8) is the three pin header next to the DC power connector. RX/GND/TX are layed out as show below. These can be connected to a standard serial cable, pins 2, 3, and 5 on an rs232 db9 connector.
NOTE: that it seems the RX/TX are swapped on some board revisions. As far as I know GND is always the center pin. If the above layout does not work, try plugging in the serial cable the other way around.
Work on getting upstream kernel on ifc6410 is tracked at the linaro wiki.
