Inphic S805 Teardown

Goes for $15 (not anymore, you snooze you lose) $40 on AliExpress, has same SoC as the Odroid C1. Looks like a poor man's Odroid to me!

We bravely attempt to build and run mainline kernel on this little board. For that we join forces with the awesome linux-meson project.

Prerequisites

• arm-linux-gnueabihf toolchain (arm-linux-gnueabihf-gcc on AUR)
• Mainline kernel clone
• Buildroot

Usage

Taken from http://linux-meson.com/doku.php

Kernel

$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- multi_v7_defconfig
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LOADADDR=0x00208000 uImage dtbs

Kernel and DTS will be in arch/arm/boot.

Rootfs

$ cd buildroot-2015.11
$ cp ../buildroot.config .config
$ make menuconfig  # customize if necessary
$ make

Copy relevant files to a FAT formatted SD card, connect to board serial port, and stop the uboot auto boot sequence. Then run:

# mmcinfo
# fatload mmc 0:1 0x21000000 uImage
# fatload mmc 0:1 0x22000000 rootfs.cpio.uboot
# fatload mmc 0:1 0x21800000 meson8b-mxq.dtb
# setenv bootargs "console=ttyAML0,115200"
# bootm 0x21000000 0x22000000 0x21800000
