Hi! I am having problems to program a STM32F107 with the STM32F4-Discovery�s STLINK SWD. I�m wondering I have forgot something very essential.

This is the circuit I've mounted: And these the errors I get: What I have done:

• Check the connections
• Check the supply
• Start in the 3 different modes: Normal, Hot Plug, Connect Under Reset
• Update Stlink firmware

Any idea what could be the problem? What is missing? I guess it must be something obvious but I don't see it :(

Thanks #stm32f4-discovery-stlink-swd

Check that you have the pin orientation correct.

 Check that you have disconnected the F4 part from the ST-LINK, via jumpers and solder-bridges are required.I'd have a pull up on the reset, and bulk capacitors on the supplies.If it were my design I'd double check the pin#
