As I work at the intersection of hardware and software, I spend a fair amount of time reading schematics for printed circuit boards (PCBs). I’m astounded at how sloppy most schematics are, and have come up with a few suggestions to consider.
Is the size of the libraries required for C++ (vs C) a concern in Embedded Linux systems? Most Embedded Linux systems likely include some C++ code, so this is probably not even a decision we need to make in many cases. However, often there is a need for a small initramfs that is used as part of the boot process (perhaps for software updates) before switching to the main root file system. In this case, it makes sense to keep the initramfs as small as possible, and we might be concerned here with the size of C++ libraries.

Recently I was asked why use systemd vs sysvinit in embedded systems? There are many discussions on this, and really most of the reasons people use it for servers and desktops are also valid for embedded systems. Lennart Poettering’s articles explain very well why you might want to consider systemd. A few things that rank high on my list:
With the BEC OE build template, you can easily set up an opkg feed server that serves up packages from your build directory. This allows… Read More »Setting up an OpenEmbedded Package Feed Server
