Hello,
Here is my circuit
By connecting ST-Link I get "'Invalid ROM table" error. However by following this "http://www.keil.com/support/docs/3566.htm" it works fine. But I need to know why my circuit should have this option but this circuit works fine without any option in KEIL. The difference is Boot1 that is not important based on Datasheet when Boot0 is connected to ground.
what is my mistake?

I can't find my problem and after programming my MCU it doesn't work properly. I don't know what is wrong with it

In addition, I use a 25Mhz crystal but the china board used 8Mhz crystal( I've changed the crystal value in Flash->configure->Targe).

I changed my crystal to 8Mhz and it works fine. I need to know
1) For any value of external crystals, how can I set this value for st-link to program my MCU without any problems?
2) Keil->configure->Target-> Xtal value is important? what about Keil->configure->Debug->St-link ->Trace->Core clock value.
