Here is an upgrade that fixes that. Some notes: It comes with a lot of "requires" in CYGBLD_ARCH_XFLAGS which that may question its role. Switching CYGHWR_HAL_CORTEXM_STM32_FAMILY from "F4" to "F3"("F2") when hard ABI is selected, leaves some unresolved conflicts. They automatically resolve after a couple interactions from user (right click -> resolve) I guess that configtool should offer this automatically.
