How to boot rootfs on an SD Card
- Get a parameter file from http://dl.radxa.com/rock/images/parameter/, make sure the root command entry of parameter file is root=/dev/mmcblk0p1
- It should now boot from SD Card
Example parameter file:
FIRMWARE_VER:4.2.2 MACHINE_MODEL:radxa_rock MACHINE_ID:007 MANUFACTURER:RADXA MAGIC: 0x5041524B ATAG: 0x60000800 MACHINE: 3066 CHECK_MASK: 0x80 KERNEL_IMG: 0x60408000 #RECOVER_KEY: 1,1,0,20,0 CMDLINE:console=ttyFIQ0,115200 console=tty0 root=/dev/mmcblk0p1 rw rootfstype=ext4 mac_addr=12:21:34:43:56:65 init=/sbin/init initrd=0x62000000,0x00800000 mtdparts=rk29xxnand:0x00008000@0x00002000(boot),-@0x0000A000(linuxroot)
Create Lubuntu SD Card
- Get a rootfs-desktop.img file from http://dl.radxa.com/rock/images/ubuntu/partitions/
- Unzip it
- Finally copy rootfs image to sd card.
$ sudo dd if=mydir/rootfs-desktop.img of=/dev/mmcblk0p1 $ sync
Resize SD Card
$ sudo resize2fs -p /dev/mmcblk0p1
Alternative way
you can make/boot (l)ubuntu from SD card without (modification to) NAND.
