Solder Bridge SB10 within STM32F3 Discovery

I got the Discovery STM32F303VCT and i had to solder the SB10, because even if the UM1570-User Manual says the SB was made it wasn�t. I soldered to use printf with Keil.

After this board modification i got a lot of problems with interrupts;

EXTI0_IRQn are redirected to EXTI9_5_IRQn and others like UART4 don�t work.

Could these interruptions issues be related to made the SB10 ?

Connecting PB3 (SWO) to the ST-LINK doesn't strike me a causally related to the interrupt issues.

I wouldn't use printf() under interrupt, by that's a different matter.

Hello Clive1,

you was right, it wasnÂ´t a problem from the SB10.

thanks for your support.
