EV2400: EV2400 no acknowledge from device

Part Number: EV2400
Other Parts Discussed in Thread: BQSTUDIO

您好!

1. 打开软件后发现EV2400 no acknowledge from device

2. 也看到过一个提示是operation failed because initial read of all data flash failed

3. 点击data memory时发现import from file(advanced)显示灰度,无法选择

烦请指导一下如何解决,谢谢!
