Hardware requirement for Zephyr

[pradeep-ng]

Hi,
Can someone provide details about the minimum hardware requirement for Zephyr? Like what is the processor architecture, memory - RAM, Flash etc?

Thanks

It differs widely depending on features/drivers/subsystems you need. Zephyr provides minimal sample that can be use to examine that https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/basic/minimal. So it depends on the application you want to develop. Minimal ROM size is 2-3kB with multithreading disabled and timers disabled. It supports wide variety of arch: arm, xtensa, risc-v among others. Please check https://docs.zephyrproject.org/latest/boards/index.html# where you can find supported boards and get better feeling what are the HW requirements for Zephyr
