Hi to all, I'm trying to program my iNemo based custom board with the ST LINK provided with the STM32F4 Discovery. When I try to connect with STM32 ST-Link Utility I get the error: '' Core is held in reset''.

Another trial was to use CoCox, and trying to flashing with it I get (''Error: Flash driver function execute timeout Erase: [ 0%] '').

Any idea to solve the problem? Thanks

Make sure the NRESET pin is disconnected from the F4, then investigate why it might be held low in your design, and check if it is.
