Installation
Booting CRUX-ARM from uSD
This info is based on http://linux-sunxi.org/Bootable_SD_card.
To install the current release we need to setup an uSD card with 2 partitions after cluster 2048 (see http://linux-sunxi.org/Bootable_SD_card#Partitioning for details). The first partition must be vfat formated, required for bootloader's stuff and the second one must be ext2, ext3 or ext4 formated and will contain the files from the release and current kernel modules.
- First to activate the bootloader we need to write directly to the card with 'dd' command (sdX directly without specifying the partition):
dd if=sunxi-spl.bin of=/dev/sdX bs=1024 seek=8 dd if=u-boot.bin of=/dev/sdX bs=1024 seek=32
- Then on the first partition we must put these files:
- uImage-3.4.61-cubieboard_20130927 After download rename it to uImage which is used in boot.scr
- boot-mmc.scr and rename it to boot.scr
- boot-mmc-serial.scr and rename it to boot.scr if you will use serial output
- script.bin
- For the second partition, download and place contents from these files:
- crux-arm-rootfs-3.2-cubieboard.tar.xz (last release)
- modules-3.4.61-cubieboard_20130927.tar.xz (kernel modules)
Configuration
We should setup all the important files: pkgmk.conf, prt-get.conf, inittab, fstab, rc.conf, net ...
Serial Console
To obtain serial access we need to make some modifications to this file:
- Uncommenting and changing the line in /etc/inittab:
s1:2:respawn:/sbin/agetty 115200 ttyS0 vt100
- In the client side (using minicom here) it's needed to disable hardware flow control to get input events working.
Udev Rules
- Add these values to /etc/udev/rules.d/50-mali.rules
KERNEL=="mali", MODE="0660", GROUP="video" KERNEL=="ump", MODE="0660", GROUP="video"
