Can anyone help me? I am using RLink STD to JTAG prog/debug my STM32F103RBT6 on Olimex header broad. When I click on and Write/erase on Reflasher7: takes seconds to come out a window with "Cortex drv error : cannot communicate with Target" right after programming window pops up.

I used that same RLink STD + Ride6/Rflasher to prog/debug another STR7110 on Olimex header broad before; it WORKS fine.

What going on with the STM32?

Thanks,
Keith
