HI, When you say "changing the makefiles" who's makefiles are these? -> for example lib/rtems-4.11.2/c/src/lib/libbsp/arm/stm32f7/Makefile.am in order to include my USB .c and .h files
Did you merge your code into the RTEMS source tree? -> yes, there was no support for USB in the code base I had Do you have a JTAG debugger that can set breakpoints and step at the instruction level? -> yes regards, Catalin On Wed, Sep 26, 2018 at 1:10 AM Chris Johns <chr...@rtems.org> wrote: > On 25/09/2018 21:37, Catalin Demergian wrote: > > what does it mean exactly to run with the RTEMS master ? > > This is our short hand for saying use the development version of RTEMS, > specifically the next release called RTEMS 5.
