Can't program CY8CPROTO-062-4343W in Mbed Studio

[PaYe_4603801]

Hello,

I’ve built a simple application in Mbed Studio and want it to run on the device.

But “triangle button” is inactive.

Important detail: when I connected my platform by USB, I wasn’t prompted to make it active platform.

Nevertheless I selected my platform in the list of platforms.

But still don’t see the USB sign at the left of platform name, that should mean that Mbed Studio recognized my platform.

Any suggestions ?

Thanks.
