MSP430FR2355: new MSP430FR2355 chip programming

Part Number: MSP430FR2355
Other Parts Discussed in Thread: MSP-EXP430FR2355,

大家好,我用MSP430FR2355芯片为主控芯片做了一个PCB板子,试图用MSP-EXP430FR2355开发板上的编程器和仿真器下载程序,发现无论怎么尝试,我的CCS软件都显示error connecting to the target: unknown device。我的PCB上的连接没有问题。请问对一个新的MSP430FR2355编程需要bootloader吗?如果需要的话如何把bootloader导入芯片?对一个新的MSP430FR2355编程需要哪些步骤?

如图是我用的仿真器(黑色)和MSP-EXP430FR2355开发板,上面有自带的编程器,可以用于编写其他的MSP430FR2355芯片。
