mpu_noexec_ram

Tests for the pmp_noexec_ram pseudomodule. Only supported on RISC-V devices with PMP.

Output

With USEMODULE += pmp_noexec_ram in Makefile this application should execute a kernel panic, stating Instruction access fault (0x01) in the mcause register. Without this pseudomodule activated, the hard fault will be triggered by Illegal instruction (0x02) instead.
