It seems that gcc 5.2.0 has a new (secret …. !) option: -mslow-flash-data https://github.com/winksaville/gcc-5.2.0/blob/master/gcc/testsuite/gcc.target/arm/thumb2-slow-flash-data.c Author Posts Log In Register Lost Password Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
