Now that's a separate toolchain target. $ grep mpc55xx_spe.inc * mpc5566evb_spe.cfg:include $(RTEMS_ROOT)/make/custom/mpc55xx_spe.inc mpc5674f_ecu508_app.cfg:include $(RTEMS_ROOT)/make/custom/mpc55xx_spe.inc mpc5674f_ecu508_boot.cfg:include $(RTEMS_ROOT)/make/custom/mpc55xx_spe.inc mpc5674fevb_spe.cfg:include $(RTEMS_ROOT)/make/custom/mpc55xx_spe.inc mpc5674f_rsm6.cfg:include $(RTEMS_ROOT)/make/custom/mpc55xx_spe.inc phycore_mpc5554.cfg:include $(RTEMS_ROOT)/make/custom/mpc55xx_spe.inc Updating to gcc 9 will require adding the powerpcspe target and using it only with these powerpc BSPs. How do we proceed? These are not my BSPs and I don't know enough of their details to unwind the solution. Only that the toolchain split into two targets and this BSP is impacted. > > --joel >
