I am looking for working MPU inplementation for Cortex-M MCUs. Tried the tree I pulled off https://github.com/mdavidsaver/qemu.git and couldn't get it to work as expected. Can anyone share their experience with this code? My code is put into ROM adress @ 0x00000000:
I'm trying to set up region #2 starting from address 0x20000000 (SRAM). But as soon as MPU is turned on, the very next memory access @ label f1 crashes qemu after a hang of ~60 sec. This is the output: qemu: hardware error: ssys_read: Bad offset 0xffc Any insight? -- |
