Display and light control evm 工具与板子 I2C通信问题

Other Parts Discussed in Thread: DLPA3000, DLPC3478

您好,

我们的板子是DLPC3478+DLPA3000配置,投影机跟cy7c65215工具通过I2C连接,I2C总线上无类似MSP430单片机,在使用Display and light control evm 工具时,界面提示如下,无法通信,实际投影机已经启动完成,在正常投影splash图,但是在advance下,去掉GPIO handshake是可以通信的;使用composer工具也可以通信;请帮忙确认下是硬件连接上没接好还是Display and light control evm工具协议有特别要求?
