Hi, I'm curious about the level of support that modern Linux offers for low-end platforms that lack MMU components, such as the ARM Cortex-M family. Specifically, I'm interested in the memory protection capabilities that Linux provides on these platforms. While the ARM Cortex-M family offers an MPU (memory protection unit), I haven't seen many features related to it in the Linux kernel. Please let me know if I'm mistaken, and any additional information would be greatly appreciated. Thank you! Best Regards, Andy
