Which Linux version used for ARM cortex M4 ?? and how to install this linux version on TDA3x from Texas instruments ??
You can run uClinux which doesn't need an MMU.
My kit (tda3x) has MMU
I see it says MMU in the diagram for it. But I'm not convinced they have a memory management unit in the sense meant here. They use MPU to mean microprocessor so they may have avoided saying MPU in that space. Cortex M4 comes with a memory protection unit abbreviated to MPU. Or tthey might simply mean the controllers for the memory.
