No device found on target

[Hesseltjuuh]

I can't seem to connect to my STM32F401RCT6. This is the schematic below and all the jumper wires are working. 

Can anyone spot the error?

When i try to connect to it i get the message 'No device found on target'

• VCAP needs a 4.7 uF bypass capacitor to GND.
• VREF+ is also VDDA which needs connected to VDD.
• HSE is limited to 26 MHz max.
• BOOT0 shouldn't be floating, should generally be tied to ground, although you can override it by programming an option byte.
• Pin 64 is VDD, not VDDA, and should be tied directly to VDD.

+ boot0 needs pulldown to gnd or gnd.
