If you work with current mainline RTEMS sources then the process
to build RTEMS has changed. This is my build scrip for
test of tms570ls3137_hdk_sdram, it builds but there is some
issue to run BSP on TMS570LS3137 which can be caused by my
load method or changes for Cortex-R5 found on TMS570LC4357.
I have not found time to investigate that yet and that
platform is not our actual priority.

My RTEMS build script looks following way now

----------------------------------------------
#!/bin/sh

MY_DIR="$(cd "$(dirname "$0")" ; pwd -L )"

RTEMS_DIR=../../../git/rtems

$RTEMS_DIR/waf bspdefaults --rtems-bsps=arm/tms570ls3137_hdk_sdram -t "$RTEMS_DIR" -o "$MY_DIR" --prefix "/opt/rtems/6" >config.ini || exit 1

#mv config.ini config.ini.default
#sed <config.ini.default >config.ini \
  -e 's/^RTEMS_POSIX_API .*$/RTEMS_POSIX_API = True/' \

$RTEMS_DIR/waf configure -t "$RTEMS_DIR" -o "$MY_DIR" --rtems-config "$MY_DIR/config.ini" --prefix "/opt/rtems/6" || exit 1
$RTEMS_DIR/waf || exit 1
$RTEMS_DIR/waf install || exit 1
----------------------------------------------

Generally, after $RTEMS_DIR/waf bspdefaults you can edit
config.ini.

You can change

TMS570_USE_HWINIT_STARTUP = False

to

TMS570_USE_HWINIT_STARTUP = True

in the config.ini. It can be automated by

  -e 's/^TMS570_USE_HWINIT_STARTUP .*$/TMS570_USE_HWINIT_STARTUP = True/' \


There are lot of other options which can be adjusted.

Best wishes,

                Pavel
