the problem is just that it is already on a board. But PC10/11 seems to close enought for some beautiful cuts and bridges Thank you

Yes, it do the problem is just that it is already on a board. But PC10/11 seems to close enought for some beautiful cuts and bridges

Re: Using PA9/10 for UARTD1
Oh, haven't seen this. I've taken a look to the STM32F4DISCOVERY USB_OTG_FS Schematic (Sheet 5).
PA9 is the VBUS_FS, I understand it as supply for the EMIF02-USB03F2. But when PC0 is high, the supply is disabled. If I measure PC0 it is high. When UART TX is inactive PA9 is high, thats why the led ...

Using PA9/10 for UARTD1
Hi,
I'm working on a Project were an xbee module over UART is used. The Board is the STM32F407-Discovery. During development I used UARTD1 on PB6/7. Since this pins are used for CAN, I changed to PA9/10 but only rubbish came out.
I reduced toe problem to the UART example where I got the same result ...
