Loading FW to STM32 IoT Discovery Kit

Hi there,

I got stuck at the most basic step but couldn't find a step-by-step guide to get through it. Any pointer to a guide for me to follow is appreciated.

I am trying to download a built FW to my STM32 IoT Discovery kit. However, when i connect microUSB cable to the PC and the ST Link port on the board, the PC does not detect any new device. What should I do to get the code downloaded to the board?

What I have: STM32 IoT Discovery kit part#: B-L475E-IOT01A, a micro USB cable, a piece of FW code generated by STM32 CubeMX, and built in Eclipse IDE and GNU Tools ARM Embedded.

Any hint or link to the guide is appreciated.

Thanks,

Cho
