Steps for upgrading from r92 image to r96

[netbug1010]

I have been using the r92 image for quite a while, I am pretty satisfied with the experience. Now, with the r96 release, I am wondering if there is a way I can upgrade the OS from r92 to r96 without destroying the existing data on the SDcard.

Any help will be appreciated.

You won't be able to update to r96 with our release image, at least we have not found a way to do that without heavily modifying the OTA mechanism within Chromium OS and cros_sdk anyway.

You can, however, setup your own development build environment and produce a newer build yourself; then setup a devserver instance and run it somewhere accessible from your Chromium OS image. Use the devserver to generate an update payload and then serve it to your Chromium OS. To break down, the steps are:

• Follow the README of this project and make your own build, for example r96 at the time when this comment was written
• Setup the devserver and spin it up
• Modify your current Chromium OS /etc/lsb-release file and edit the update server URL to point to your local devserver
• Use devserver commands to generate a update.gz payload from your successful build
• Wire things together so that your Chromium OS can update via your local devserver

It's not very hard indeed, however, if you do find this tedious, FydeOS for You - Raspberry Pi 400 does that all for you, at a small cost.
