Choosing Embedded Linux for device

I am starting to create a QT application with sqlite for a hand held device. My Project Manager asks me to select an operating system (embedded linux) for the device (we are not considering android).

As in Desktop, are there many embedded-Linux distributions for devices? If so, Which embedded linux I should consider?

You can use Qt for embedded device , it’s fast and compatible with many hardwares and if your hardware is not supported, porting it to a new hardware is not so hard plus it has special rendering system

You have multiple choices, but I will suggest the easier and - in my opinion - better two.

  • Buildroot - is a set of makefiles that lets you create your custom embedded distribution. Can take care of building the Linux kernel, the toolchain and a barebox or U-Boot bootloader, too. Easily expandable and with a practically zero learning curve. You have a fully working system in a matter of hours.
  • Yocto - a fully fledged (and complicated) build system. Suggested over Buildroot when you need a LOT of packages/components and may need flexibility in expanding the system directly on premises. What you can do substantially depends on the "layers" (sets of rules for building things) available: you combine layers together to obtain your system. Has a steep learning curve but is used and directly supported by multiple vendors (e.g.: Atmel, TI).

Anyway, unless you have more than good reasons, I strongly suggest the former.

This is a difficult question to answer not knowing more about the project requirements (not just software requirements, but also non-functional ones as well) and capabilities of the platform.

Angstrom (based on OpenEmbedded) is another possibility for Linux.

I would challenge the assumption that the operating system must be Linux. Why? If time-to-market or having commercial support are important, you might be better off with commercial embedded or RT operations systems such as VxWorks or QNX.

There are also professionally supported Linux distros such as Montavista

Whilst free linux distros are, well, free, you are generally on your own and your team's time isn't free.

There are several Linux distros to be used with ARM. Maybe you should consider Fedora ARM https://fedoraproject.org/wiki/Architectures/ARM
