[jira] [Commented] (MYNEWT-259) Bootloader for olimex_stm32-e407 won't build

["Marko Kiiskila (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MYNEWT-259?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15269509#comment-15269509 ] 

Marko Kiiskila commented on MYNEWT-259:
---------------------------------------

I don't think you have build_profile variable set.

You'll be missing key compiler cflags then. Including one that says that you're compiling for cortex-m4.
