采用UCD9222+ucd7242为dsp6678供电。采用ti的USB adapter下载线 ,用fusion design设计电源输出,能检测到ucd9222的地址(78),能检测到输入电压12v。
问题:1、输出为零提示输出的电源和电流overvoltage,overcurrent。
2、PMBUSALERT 显示警告
我如何确定我的PMBUS已经正常工作并下载命令到板子上了?
已经上传.xml文件,请问该如何解决此问题?
Zihao Wang:
Your device's PMBus configuration for rail #1 is out-of-sync with the compensation and/or power stage design calculated by the Design tool. Based on what you have checked in the "Design -> Device Synchronization" settings for this device, the following PMBus commands are out-of-sync: IOUT_CAL_GAIN_1 Select an action below. If you skip the write, you can always come back later and click the "Write to Hardware" button. 一直提示我这个?不知道什么意思?

原理图与评估板基本无差别。估计是你Fusion Design软件设置问题。
