Re: So you want to build an embedded Linux system?
#3Since an embedded Linux system will likely require use of either Buildroot or Yocto, I'd like to ask the following slightly off-topic question:
Which SoM product line would you say has the best vendor support? I'm talking about quality of the BSP (board support package). (A meta-layer, in Yocto terms.)
Raspberry Pi has quite a community behind it, so meta-raspberrypi has a number of contributors. (None of which payed by the Raspberry Pi foundation, though.)
My latest project involved a NVidia Jetson SoM, and I was surprised to learn that the BSP doesn't see any support from NVidia at all. They rely on one motivated guy (Matt Madison) maintaining it in his free time.
I'd love to see a vendor that provides a first-class BSP maintained by their own people.

I have done quite a bit of yocto work at $dayjob, and having a vendor-supported upstream BSP is (usually) really pleasant to work with.

Yes, NXP's Yocto support has been fantastic.

#6Excellent blog! Love the fact that a great amount of background information is added to the article. Can be read as an "introduction to embedded programming" chapter but not as boring as you find in textbooks.

I don't know if that's the case anymore. The kernel ships with a lot of drivers now, and Root FS for embedded devices aren't really space constrained anymore. The needs of an IoT device have also grown to include things like containers and telemetry. In my experience, forking off of an existing distribution like Debian is way easier than navigating Buildroot or Yocto's documentation and cruft, and results in faster builds.
I got so fed up with those tools I eventually built a custom tool (Etcha) to build my own meta distribution (EtchaOS) of immutable variants for Debian, Fedora, etc. It owns the entire provisioning pipeline and builds multi-arch images in less than 10 minutes:

Agreed, NXP does a good job with their yocto layer.

I've been getting a lot of traction over the past 10 years with Debian multistrap and just the kernel from the BSP. I've never needed Buildroot or Yocto.

unrelated but curious - what do you think of OSTree-based embedded distros? Any future in it?
