I have chose the STM32F405RG and the st-link debugger.

The program is used for STM32F407-DISCOVERY at first.It can work at the STM32F407-DICOVERY,but after I changed the device and other options.

Make sure to use ''SWD'' mode.

See if adapter is visible as ''ST Link (Deprecated)'' if it has older firmware. For problems with software on the board, reset with BOOT0 = High

I was use the ''JTAG'' mode,and I'm sure that I have connected right in the light of the datasheet.

But both BOOT0 and BOOT1 connect nothing.May it is wrong here?

One more question,when I use I2C,the voltage is up to 5V.

And it have been connected to the pin-29 and pin-30.May I do like this?
