1.4 About FM4 peripheral Demo Project
This is a sample project to demonstrate how to use FM4 peripheral board. It is developed in IAR EWARM Workbench
V6.60, and works on SK_FM4_U120_9B560
Note:
1. If the later version of IAR EWARM Workbench V6.21 is used to open this example project, MCU type information
in project setting may lose, please check it.
2. If user select the “Use CMSIS” option (in Library Configuration table of General Options) with IAR EWARM
Workbench V6.20 later, please erase the head files with prefix “core_” in common folder (path: ..¥..¥common).
3. If the former version of IAR EWARM Workbench V6.21 is used to open this example project, MCU type, pre-
included files (in preprocess table of C/C++ compiler), icf file (in link table of debug option), flash loader file (down
table of debugger option) may lose, please check these settings.
4. if the former version of Keil μVision V4.20 is used to open this example project, MCU type, pre-included files (in
C/C++ table of project option), debug setting (in debug table of project setting) may lose, please check these
information.
5. If user uses former version of IAR EWARM Workbench V6.20, it is a MUST to copy two files (core_cmFunc.h and
core_cmInstr.h in cmsis_low_ver folder in current project directory) to common folder (path: ..¥..¥common).
