Manually install Debian Stretch with minimal Rootfs

This is a step by step illustration for how to install Debian Stretch minimal Rootfs to a bare metal Innostick 6.

Pre-requirements

• An Innostick 6 single board computer
• A Linux Host machine
• An USB to Serial Cable USB to Serial TTL Converter
• Pre-built U-Boot image, Linux kernel image, Linux kernel modules and DTBs
• Linaro stretch-armhf-rootfs: https://releases.linaro.org/debian/images/developer-armhf/17.08/linaro-stretch-developer-20170706-43.tar.gz

Procedures

1. Connect Dupont headers of USB to Serial cable to Innostick 6 UART1

Connection details:

Dupont Header	Innostick 6 UART1

4. Connect Micro-USB cable between Windows host and Innostick 6 P1.
5. Wait until an USB mass storage gadget device recognized by Linux Kernel

esky-sh@ubuntu:~$ lsblk

└─sda1   8:1    0   49G  0 part /

6. Format Linux EXT4 partition, in this case it is "/dev/sdb2"

esky-sh@ubuntu:~$ sudo mkfs.ext4 -F -E nodiscard /dev/sdb2
mke2fs 1.42.13 (17-May-2015)
/dev/sdb2 contains a ext4 file system
        last mounted on /mnt/udisk on Fri Aug 24 21:46:26 2018
Creating filesystem with 3663360 4k blocks and 917504 inodes
Filesystem UUID: 2e70e95e-f14b-41e0-b756-a85ee8ef051d

7. Mount Linux EXT4 partition

esky-sh@ubuntu:~$ sudo mount -t ext4 /dev/sdb2 /mnt/udisk

8. Extract Rootfs tarball to this partition

esky-sh@ubuntu:~$ sudo tar -zxvf /mnt/hgfs/sharefd/linaro-stretch-developer-20170706-43.tar.gz --strip-components 1 -C /mnt/udisk/ binary/

9. Mount FAT partition, in this case it is "/dev/sdb1"

esky-sh@ubuntu:~$ sudo mount -t vfat /dev/sdb1 /mnt/vfat

10. Copy pre-built U-Boot image, Linux kernel image and DTBs to FAT partition
11. Copy Linux kernel modules to /lib/modules folder on Linux EXT4 partition

esky-sh@ubuntu:~$ sudo mkdir /mnt/udisk/lib/modules
esky-sh@ubuntu:~$ sudo cp -R /mnt/vfat/4.9.88-ge8dbe4d/ /mnt/udisk/lib/modules/
esky-sh@ubuntu:~$ sync
esky-sh@ubuntu:~$ sudo umount /mnt/udisk/
esky-sh@ubuntu:~$ sudo umount /mnt/vfat/

12. Plug USB to Serial cable to Linux Host
Linux will automatically recognize this serial device and arrange COM port number.

esky-sh@ubuntu:/$ dmesg | grep tty
[    0.004000] console [tty0] enabled
[    4.036753] 00:06: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
