![]() ![]() You can use a Real Time Operating System like freeRTOS to help you with some of the resource management but you are much more limited in functionality.Īs pylon said, you will likely need to write and debug a lot of software. Have completely reformatted SD cards and Etcherd most recent IPFire 2.19 - Core Update 117 arm 'image for the armv5tel architecture' (the one without the serial console) on both a 4gb and 16gb SD card.

This allows you to install and run many different packages of software on one processor and build your system step by step. This allows the processor to run different software all in their own address space while the physical memory is used as needed to map that virtual address space. The Raspberry Pi has a Memory Management Unit (MMU) that allows virtual addressing. ![]() One of the major differences between a Raspberry Pi and an Arduino/ESP32 is the memory map.
