- fest 6y agoPretty much every security camera, most of the networking equipment, action cameras and set-top boxes run Linux from NOR flash (cost and simplicity reasons- no FTL, IIRC better retention). Altogether it's probably billions of devices. There are also quite a few lines of MCUs without built-in flash memory and those typically boot from external NOR flash.

One example was the vast majority of home routers. I once replaced the 4 MiB NOR flash in my home router to 16 MiB for OpenWrt (yes, you can run Linux with 4 MiB of NOR flash, this configuration was officially supported by OpenWrt until it's retired in 2019).
