Thank you for the reply.
You say I should be using an embedded Linux. Just for clarity you’re talking about Yocto/buildroot or are talking about an already existing embedded Linux distro. Powered board. Yes we will use solar but also a battery to keep the board running the solar power isn’t available. My main concern is size data space wise but power efficiency. Will a Yacto build provide more power savings than buildroot or standard Debian? Also would there be any already baked Yacto images I could use to test out to see how it runs?

Removing audio, video and usb, including from your kernel config, should drastically reduce your size. You should consider the value of a read only FS, since I'd assume you'll have random power loss due to solar being your primary power source. Yocto/Buildroot will be much better with that. For Yocto vs Buildroot, here's a good place to start for your research: https://lwn.net/Articles/682540/. In my experience, Buildroot is easy, simple, and great as long as you're building one thing. Yocto is much more powerful and if you need more than what Buildroot can provide then you're better off investing your time learning Yocto instead of learning how to modify Buildroot, IMO.

I’m trying to get my head around the benefits of using such an OS. I’m sure it’s on case by case basis so let me provide my background and requirements. Background/requirements Currently using Debian OS on my prototype build based on a Beaglebone green wireless. Custom software is constructed in java. System utilizes 9 axis accelerometer, vibration sensor, Bluetooth, WiFi, LTE-M, GNSS, power management (through BB I2c and GPIO channels) It runs on a battery and solar. Power usage is important. Standby is used and still needs to listen for vibration sensor, Bluetooth and LTE-m cellular events. Only constrained by power usage and data usage. Processor or memory usage are unconstrained except for in relation to power usage. Minimizing data usage if an OS update is needed would be an advantage. No audio , video, USB or GUI is used. So would there be a significant benefit seen by using a custom Yocto build or would a GUIless version of Debian be just as effective? Also considering Buildroot if that would be just as effective and simpler to execute. If anyone has any other thoughts or concerns I would love to discuss. Thank you for your time.
