Revision as of 11:10, 21 December 2005

With release 5 we are changing the format of the following images: -b (bootloader), -r (rootfs formerly named ramdisk) and -j (application).

That is because we do not want the phone user accidently downgrading to an "older" version. And this is because we replaced the linux rootfs, which was a ramdisk before, with a jffs2 filesystem, which is saving 2 MB of RAM. If you were allowed to downgrade as usual, the phone would not bootup anymore, because of incompatibilities of bootloader and rootfs.

A full process of updating to release 5 needs the following:

  1. snom3X0-5.0a-SIP-j.bin: Application part of release 5 which introduces the new image formats, everything except the ethernet switch properties control is working. Downgrading manually via TFTP is still possible.
  2. snom3X0-ramdiskToJffs2-br.bin: New bootloader and rootfs with new image format each, which can be updated by application part release 5 or above only. This saves 2MB of RAM and brings a TFTP update application which is able to update application images with version 5 or above only. So now you cannot downgrade in one step via manual TFTP update anymore.
  3. snom3X0-3.25-l.bin: This linux is needed to make the ethernet switch properties control work.

Nevertheless it will be possible to downgrade your phone, but this is a more complicated two step procedure.

So 1) and 3) without 2) will give you full functionality and the option of an usual manual downgrade via TFTP.

Meaning of a/b application firmware versions:

a=first time moving to 5.0, b=Already on 5.0

Like in: snom3X0-5.0a-SIP-j.bin and snom3X0-5.0b-SIP-j.bin
