+unzip latest.zip
+cd tamago-go-latest/src && ./all.bash

+additional = """The issue relates to the fact that the NonSecure World, at startup, configures
+the MMU with the NX bit for the entire address space not belonging to its
+firmware .text area.
+
+On real hardware this MMU configuration by NonSecure world does not affect the
+Secure World translation tables.
+
+On qemu 9.1.0, however it does and this is inconsistent with real hardware
+behavior. On qemu 9.0.0 the behaviour is correct so the issue has been
+introduced between these two releases.
+
+The switch between Secure and NonSecure is done
+[here](https://github.com/usbarmory/GoTEE/blob/7e62563c0628fed3ee0aebb4702e22be9bb636e3/monitor/exec_arm.s#L73).
+
+The MMU first level address table which sets the NX bit is done
+[here](https://github.com/usbarmory/tamago/blob/273d67cd811dfcb1782c0fe596ac14d43d0ce117/arm/mmu.go#L85)."""
