 # stmos
+
+stmos is an operating system for STM microprocessors. It aims to support (or be able to support) all STM Cortex-M processors.  
+  
+Features:  
+* Unprivileged code execution
+* ELF loading and execution (loads an init from the initrd)
+* Near-full C standard library support for loaded ELFs
+* libgpio: GPIO access for loaded ELFs
+  
+Currently supported processors:
+* STM32L476RG (board: NUCLEO-L476RG)
+  
+### building  
+To build stmos, you'll need the following programs:  
+* The arm-stmos toolchain (see the ```arm-stmos``` folder)
+* openocd
+* gdb (with multiarch support)
+  
+To compile stmos simply run ```make``` (-j option supported). To upload, use ```run.sh``` to start openocd/gdb; do ```lo``` to load stmos, and ```c``` to run it.  
+  
+### notes
+Only the initrd works right now in regards to filesystem access. Files in the folder ```src/initrd/files``` are put into the initrd. C source files in ```src/initrd``` are compiled with libgpio, placing the program in ```src/initrd/files```.  
+  
+What's next for stmos?  
+* SD card support
+* Display support (ILI....)
+* Script program support (a shell like sash, maybe lua)
+* More ELF work (better execve, signals?, etc.)
