This is a simple example to show how to write a uVisor-secured threaded application. Three LEDs will blink from three separate secure processes. Each process also updates some memory private to that process. The memory allocator is also used in this example.
The example currently only works on K64F with the GCC_ARM toolchain.
For a release build, please enter:
$ mbed compile -m K64F -t GCC_ARMYou will find the resulting binary in BUILD/K64F/GCC_ARM/mbed-os-example-uvisor-thread.bin. You can drag and drop it onto your board USB drive.
When a debugger is connected, you can observe debug output from uVisor. Please note that these messages are sent through semihosting, which halts the program execution if a debugger is not connected. For more information please read the Debugging uVisor on mbed OS guide. To build a debug version of the program:
$ mbed compile -m K64F -t GCC_ARM --profile mbed-os/tools/profiles/debug.json -c
