I am using

Micro controller: STM32F103RCT6TR

IDE: IAR Embedded workbench

Debugger: J-Link ARM  

When I burn it I am getting this error

TotalIRLen = ?, IRPrint = 0x..000000000000000000000011

Fatal error: Failed to read CPUID for Cortex device   Session aborted!

Can anyone help me?

Thank you,

In IAR I set in ''project/options - ST-Link'' in ''Reset'' choose ''connect during reset'' and a problem was solved
