OK, so it turns out delta updates don’t work with the base image integration for `tegra-demo-distro`. See this issue as well: [Mender delta update issues with demo distro · Discussion #198 · OE4T/tegra-demo-distro · GitHub](https://github.com/OE4T/tegra-demo-distro/discussions/198)

I’d really like to solve this problem, we’re currently holding back on getting a professional license for Mender (for the delta updates) because we can’t get it to work. I’d gladly contribute to the project to submit a fix, if only I had a strategy to dig deeper into it.

Is it possible for someone who knows about the Yocto/Mender integration to look at this? Thanks in advance. @kacf perhaps? (forgive me for the direct referral, I’m including you because you’ve written [this](https://hub.mender.io/t/robust-delta-update-rootfs/1144) post).
