From 9279fd42793123784ce83ca151df6f4630487722 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Fri, 16 Mar 2012 20:21:09 -0700 Subject: Add STM platform and stm-bringup demo program The stm-bringup doesn't run altos, it just initializes the device and writes stuff over a serial port. Works on the STM32L Discovery board at least, should do stuff on other boards too.
