Hi ,
I am about to draw the schematics of a card which has STM32F405RG on it. I want to program my card throug SWD port. I made the pin connections as I described below:
 NRST: pulled up to VDD with 100K
SWDIO: pulled up to VDD with 100K
SWCLK : pulled down to GND with 100K.
Are these conections are correct?
I have STM32F4 discovery kit when I look at the schematics of the discovery board I see that SWDIO is pulled to low, SWCLK is pılled to high and NRST is pulled to high. However on the document http://support.code-red-tech.com/CodeRedWiki/HardwareDebugConnections it is recommended to connect as I did.I could not decide which one is correct. I will be very glad if you can help me. Thank you very much. ..
