在PC上无法检测到VCP和DFU

嗨，


我刚买了新的MKI109V2主板，并为DFU和VCP安装了驱动程序。开始时，我可以在PC上检测VCP并使用DFU DEMO升级固件。升级固件DFU_Patcher_V1.0.2.dfu后，我无法再检测到VCP，但仍能通过DFU DEMO升级FW，然后在PC上无法检测到VCP和DFU。现在我的主板D5 LED始终亮着。

我的问题是如何用固件应该重新编程它。我从stsw-mki109w的软件包中获得了eMotionV2_REL_4_2.dfu。

谢谢！

Hi,


I just got new MKI109V2 motherboard, and installed the driver for DFU and VCP. At the beginning, I can detect VCP on my PC and use DFU DEMO to upgrade firmware. After upgrading firmware DFU_Patcher_V1.0.2.dfu, I cannot detect VCP anymore but still be able to upgrade FW via DFU DEMO and then none of VCP and DFU was able to detected on PC. Now my motherboard D5 LED is always ON.

My question is how I can reprogram it with what firmware is supposed to be. I got eMotionV2_REL_4_2.dfu from the package of stsw-mki109w.  

Thx!
