Introduction

Enabling USB Support is porting specific drivers from FreeBSD The first one is DWC OTG

Getting started

  • Raspberry Pi required
  • Configure and RTEMS with these args --enable-rtemsbsp=raspberrypi --enable-posix --disable-networking (you will need mailbox sources, if not yet merged, you can get them ​here)
  • Get libbsd sources with DWC OTG driver (if not yet merged, ​here)
  • Ensure testsuite app, you want to try, has these lines: 
    #include <bsp/nexus-devices.h>
SYSINIT_NEED_USB_CORE;
SYSINIT_DRIVER_REFERENCE(bcm283x_dwcotg, nexus);
  • Configure and build libbsd
  • Run testsuites and enjoy!
