Preparing rootfs

In this tutorial Debian Lenny will be used. The build process may vary, depending on host PC system. The following instructions are tested on Ubuntu 18.04.

Install required packages:

sudo apt-get update
sudo apt install -y debootstrap qemu-arm-static mtd-utils

Create empty directory, which will contain the new rootfs:

mkdir armel-lenny

Run debootstrap and wait to finish:

sudo qemu-debootstrap --arch armel lenny ./armel-lenny

Login into the new rootfs with:

sudo chroot ./armel-lenny

Set hostname and password:

echo 'sam9-l9260' > /etc/hostname
passwd

Set locales:

apt-get install locales
dpkg-reconfigure locales

Install some additional packages:

apt-get install autoconf autotools-dev bash-completion bind9-host binutils busybox cpp ethtool ftp initramfs-tools less lsof m4 mime-support mtd-utils ntp openssh-client python telnet texinfo udev usbutils whois

Exit from chroot:

exit

Generate JFFS2 image

Run:

sudo mkfs.jffs2 -r armel-lenny/ -o lenny.jffs2 -e 128 -s 512 -p -n

Where:

• -e 128 - 128KiB of erase block
• -s 512 - 512B page size
• -p - pad the output to match erase block size
• -n - do not write cleanmarkers
