能否贴个最小系统电路图以便检查是否硬件电路问题?
另外是否已经参考过上面那个链接给出的对应措施?
Hi May May,
Please check if the MCU is in the support list of USB MULTILINK.
Please attached the circuit of MCU(how did you connect it with MCU)?
You can refer: How To Sucessfully Program a Custom made Kinetis Microcontroller Board.
Best Regards,
Robin
