Cortex-M4 is the "smallest ARM" with an MPU IIRC (Or was it M7??). RP2040 is Cortex-M0+ which shouldn't have MPU, from my memory.
- dmitrygr 4y ago100% wrong C-m0+ has an optional MPU: https://developer.arm.com/documentation/dui0662/b/Cortex-M0--Peripherals/Memory-Protection-Unit https://developer.arm.com/documentation/dui0662/b/Cortex-M0-... RP2040 has it: https://datasheets.raspberrypi.com/rp2040/rp2040-datasheet.pdf https://datasheets.raspberrypi.com/rp2040/rp2040-datasheet.p.... (page 76)
