Perhaps the part isn't actually functioning?

Check orientation

Check pin state of NRST

Check voltage on VDDA

Make sure a stand-alone ST-LINK has both 3V3 and GND connected

Check ST-LINK with ST-LINK Utilities

Make sure you have correct debugger selected in Keil, and it can see device

Try using USART1 PA9/PA10, BOOT0 High, Reset, Send an 0x7F byte at 9600 8E1, check for 0x79 response.
