Interesting. Thanks. How does the CPU know which mode it is using? Is there an external hardware jumper that the reset logic reads? That would require a new uboot as well as kernel/userland. Or is there a mode bit that the CPU can set? (maybe in a page table) Is that feature in all ARM CPUs, or just a few? Would the same thing work on a Raspberry Pi? -- These are my opinions. I hate spam.
