# 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.
