I have a BlueNRG IDB005V1D board which is connected to its motherboard. I am trying to install firmware onto the STM32L151RBT6 uC on the motherboard but when I am prompted to enter DFU mode there is no LED flashing orange, and and the attempted flash fails.

I tried using the STM32 ST-LINK Utility also to load the DFU_Bootlader.hex but this says that there was no ST-Link device detected. The ST-Link connector that I use does work on another board.

Are there any suggestions as to how I can flash the uC?

Thank you ,
