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 #inemo #stlink #stm32f103

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.
