Is there any way to make Keil MDK exchange information with other windows application through socket ?

I want to develop a debug software. so I need the MDK to send some information (like variable value) to a debug tool (like eclipse) and receive debug…

The scenario is STM32L0 (ST Nucleo evaluation board) and custom firmware.

When I execute the code in debug mode and it stops at main function, the value of FLASH->SR is 0x0000000C, and it looks good for me.
Now, without running the code, if I simply…

hi,

 earlier i was working on PIC controller, now i am shifting to ARM and i am having stm32f401re NUCLEO64 evaluation board.
