使用Fusion Digital Power Designer连接不上UCD9222

Other Parts Discussed in Thread: UCD9222, UCD7242

您好,我试图用USB Interface Adapter配置UCD9222+UCD7242组合,使用的软件是Fusion Digital Power Designer(Version 7.1.1),提示如下图。电路图我是参照TMS320C6678EVM的原理图连接,它推荐的上拉下拉电阻分别是clk 2K、data 2K、alt 100k、ctrl 1M接地。但软件里的选项都是2.2K,是这个原因导致的连接不上吗?我检查了3.3V电源和12V电源供应都正常,我没有接负载。
