I actually disagree.

We have lower power bare metal systems, think AVR/STM stuff (in the 1Mhz to 50Mhz range with 128K or less of RAM) here FreeRTOS, no freeRTOS, custom driver code and some basic application code makes sense. For simple to very complex systems.

Then there's 1Ghz+ stuff with an MMU and 2GB+ RAM. Linux makes sense here.

Companies are now making chips 200Mhz+, 4MB RAM, with no MMU. This is precisely where Zephyr excels, you want a full networking stack? Switch that on. A file system, easy. Driver for some more complex thing? Maybe an SDIO radio? boomboom

Flipper Blackhat: A Linux-Based WiFi Tool

from the self-post dept.

As an electrical engineer, I asked the Flipper community a while back what hardware add-ons they would like to see developed. The top reply was "evil portal that supports WiFi passthrough" meaning the user is connected to the internet after the portal attack.This got me thinking: the ESP32 is a powerful but simple, bare-metal microcontroller. They're awesome but limited in ways.If you put a...

Yup +1, I agree with you and the OP. If you work for a huge company your skill set may be extremely narrow. Buy having lots of side project will at the very least give you a talking point if you want to change to another company that might not have the exact position you were working at your current company
