Here is application note: http://www.st.com/content/ccc/resource/technical/document/application_note/51/5f/03/1e/bd/9b/45/be/CD00264342.pdf/files/CD00264342.pdf/jcr:content/translations/en.CD00264342.pdf and also here is small program which can be used to burn image to stm32 via serial bootloader: https://github.com/jsnyder/stm32ld
