This just makes the LEDs blink continually, because I have a development board sitting on my desk and I like to see it doing something. You can still force the GPIOs on and off using the tool in extra/usb_gpio/. BUG=none BRANCH=none TEST=make buildall Try it: sudo make BOARD=discovery-stm32f072 flash The LEDs blink. Force them on and off with: cd extra/usb_gpio make ./usb_gpio write -1 0 ./usb_gpio write 0 -1 ./usb_gpio write 2 0 ./usb_gpio write 4 2 To resume blinking, use ./usb_gpio write 0 0 Change-Id: Iadbe7436c02de5b6eae81885d95bad154ca3692c Signed-off-by: Bill Richardson <wfrichar@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/274131 Reviewed-by: Anton Staaf <robotboy@chromium.org>
