Discovery with external CPU

Dear all,

Thank you for reading my post. I designed a board with a stm32f101c6t6, and wanted to be able to debug it with the STM32 discovery kit.

I removed the two jumpers on CN3 and connected my board to the Discovery's CN2, and wanted to connect to it with the "STM32 ST-link utility" software. However, this one tells "No target". Removing the connector plugged in CN2 and putting back the jumpers on CN3, everything works perfeclty well with the Discovery's own target microcontroller.

Did someone else try to connect the discovery to an external board ?

On my board, the nRST signal is high, and the boot0 signal is tied low.

Do someone have any hints ?

Thank you in advance for your help.
