I have installed LPCScrypt divers in my pc, and it can recognise CMSIS-DAP interface correctly but the VCOM interface shows a Yellow exclamation point and cannot use, what's the matter with it , and how can i repair it, thanks.
Which of the two connectors of the QN9080 are you using
—— I use J2 connector, the CMSIS-DAP interface can be recognised correctly;
have you installed the SDK of the QN9080? Which example are you using
—— I have already installed the sdk, version SDK_2.2.0_QN908XCDK,I have tried some of the driver examples, I can debug them normally, but the vcom interface can not be used all of them.
Thanks.
Hi Estephania:
I'm sorry I don't know exactly what you mean, but I can tried describe my usage mode.
I debug the QN908x-DK board with CMSIS-DAP but not isp interface, also the vcom can be recognisized on my windows10 notebook computer, but cannot on my windows 7 PC.
Thanks.
