Hi, As I stated in my earlier mail, I'm trying to move my development to master branch. I have made following changes in the RTEMS git clone,
1. Created a new folder <target> for my target inside /bsps/arm/ 2. Added .inc and .cfg files for the target inside /bsps/arm/<target>/config (Modified copy of lpc32xx) 3. Added linkcmds.<target> file inside /bsps/arm/<target>/start (Modified copy of lpc32xx) 4. Created a new folder <target> inside /c/src/lib/libbsp/arm/ 5. Added configure.ac and Makefile.am inside /c/src/lib/libbsp/arm/<target>/ (Modified copy of lpc32xx) make command after bootstrapping gave me following error, checking for RTEMS_BSP... mytarget checking for perl... /usr/bin/perl configure: error: Invalid BSP configure: error: ../../../../../.././../../rtems-git/c/src/lib/libbsp/arm/configure failed for lib/libbsp/arm Makefile:731: recipe for target 'mytarget' failed gmake[2]: *** [mytarget] Error 1 gmake[2]: Leaving directory '/mnt/OS/LAP000426/RTEMS_BUILD/development/rtems/mytarget /rtems/5.00/build/LPC/arm-rtems5/c' Makefile:289: recipe for target 'all-recursive' failed gmake[1]: *** [all-recursive] Error 1 gmake[1]: Leaving directory '/mnt/OS/LAP000426/RTEMS_BUILD/development/rtems/mytarget/rtems/5.00/build/LPC/arm-rtems5/c' Makefile:410: recipe for target 'all-recursive' failed make: *** [all-recursive] Error 1 Am I doing something wrong here or missing some additional steps? *Thank you & Regards,* *Amarnath MB* On Mon, Dec 10, 2018 at 2:34 PM Amarnath MB < amarnath...@mistralsolutions.com> wrote: > Hi Jeol, > > I was doing bootstrap in the top of the tree, Thanks for your tip. > > As per Sebastian Huber suggested I'm moving my development to master > branch. > In RTEMS 5, after adding some changes in the start.S file if I give > successive make as 'make RTEMS_BSP=lpc32xx_mzx', > the changes are getting reflected in the hello.exe sample.
