Debian JFFS2 2005-10-25 (Etch)

Debian JFFS2 2005-10-25 is a root file system that is derived from the Debian (Etch) distribution and is trimmed down to fit (compressed) in a partition in on-board flash as small as 15MB. This size can be reduced further by removing the demo programs and associated data that are included in this distribution. See the main README.txt for the 2005-10-25 ADS Debian release for detailed information about the root filesystems.

The following files are included in this release:
bitsyXb/hw_config.txt
bitsyXb/tty_config.txt
bitsyXb/root_config.txt
bitsyXb/start.txt
sphere/hw_config.txt
sphere/tty_config.txt
sphere/root_config.txt
sphere/start.txt
vix/hw_config.txt
vix/tty_config.txt
vix/root_config.txt
vix/start.txt
cmdline_bitsyx.txt
MD5SUMS
register.txt
register_vgx.txt
register_agxepson.txt
flashfs1
cmdline.txt

Usage
Download the flashfs1 image from the link above and copy it to an ATA flash card. Also copy onto the card, the kernel zImage file for the kernel you want to use.

A kernel command line is required to direct the kernel to mount this filesystem during start up. Download a cmdline.txt file as shown below and copy it to the card.

A register.txt file is recommended for best performace of the video demonstration programs included in this distribution. Download the register.txt file for your system's frame buffer as shown below and copy it to the card.

Create a file named ProgramFlash.ads! on the card.

On your ADS System, set the first dip switch to ON (Flash Update Mode), insert the card, and boot your system. The bootloader will erase everything in on-board flash (except the bootloader itself) and program (copy) the images on the ATA card to on-board flash. The kernel will be loaded from on-board flash and the JFFS2 root file system will be mounted when Linux starts.

Delete the ProgramFlash.ads! file and remove the ATA flash card to prevent an unnecessary erase/reprogramming of on-board flash the next time you reboot. See the bootloader manual for more information on the dip switch settings and boot options.


Command lines
These command lines will eliminate the ramdisk partition and direct the kernel to mount the JFFS2 root file system in the third partition. See the bootloader manual for more examples.

On the BitsyX, use this cmdline.txt.

On AGX, GCX, and VGX, use this cmdline.txt.


Register Settings
These register.txt files will change the default 8bpp color depth to 16bpp. The bootloader reads the register.txt file and changes the registers before the kernel starts. Download the one for the frame buffer that is used by your board.

register.txt for PXA frame buffer and LQ64343 LCD (BitsyX, GCX, or AGX without an Epson chip)

register.txt for Epson frame buffer and LQ64343 LCD (AGX with an Epson chip)

register.txt for SM501 frame buffer and LCD or CRT (VGX)


Tar Archive
Here is a tar archive of this file system.


Verification
MD5SUMS provides MD5 checksums for all files in this release.


History
This release of our JFFS2 root file system supersedes our previous 2005-04-26-B release. It is derived from the Traditional Debian root filesystem and is similar to our Debian Ramdisk root file system but with X11 instead of Microwindows / nano-x and with more features, demos, etc.
