If you are using an Arm device from the CMSIS v5 pack, you need to switch the device selection to one of the supported devices in the new Cortex_DFP pack. The following table shows the available mappings:
| CMSIS v5 | Cortex_DFP |
|---|---|
| ARMCM0 | ARMCM0 (NO_FPU, NO_MPU) |
| ARMCM0P, ARMCM0P_MPU | ARMCM0P (NO_FPU, MPU) |
| ARMCM1 | ARMCM1 (NO_FPU, NO_MPU) |
| ARMCM3 | ARMCM3 (NO_FPU, MPU) |
| ARMCM4, ARMCM4_FP | ARMCM4 (SP_FPU, MPU) |
| ARMCM7, ARMCM7_SP, ARMCM7_DP | ARMCM7 (DP_FPU, MPU) |
| ARMCM23, ARMCM23_TZ | ARMCM23 (NO_FPU, MPU, TZ) |
| ARMCM33, ARMCM33_TZ, ARMCM33_DSP_FP, ARMCM33_DSP_FP_TZ | ARMCM33 (SP_FPU, MPU, DSP, TZ) |
| ARMCM35P, ARMCM35P_TZ, ARMCM35P_DSP_FP, ARMCM35P_DSP_FP_TZ | ARMCM35P (SP_FPU, MPU, DSP, TZ) |
| ARMCM55 | ARMCM55 (DP_FPU, MPU, FP_MVE, DSP, TZ) |
| ARMCM85 | ARMCM85 (PACBTI, MPU, DP_FPU, FP_MVE, DSP, TZ) |
| ARMSC000 | ARMSC000 (NO_FPU, NO_MPU) |
| ARMSC300 | ARMSC300 (NO_FPU, NO_MPU) |
| ARMv8MBL | ARMCM23 (NO_FPU, MPU, TZ) |
| ARMv8MML, ARMv8MML_DSP, ARMv8MML_SP, ARMv8MML_DSP_SP, ARMv8MML_DP, ARMv8MML_DSP_DP | ARMCM33 (SP_FPU, MPU, DSP, TZ) |
| ARMv81MML_DSP_DP_MVE_FP | ARMCM55 (DP_FPU, MPU, FP_MVE, DSP, TZ) |
To reduce the functionality of the new device mappings, use the appropriate compiler flags. Please consult the toolchain manual for the compiler flags.
