When I try to debug my target board with stm32f105 with st-link (from discovery board), I get a message "internal command error". After, I get few messages "Error while attempting to read 64 bytes from memory 0x00000000" After cliking OK I get error messages again with address of memory increased by 1. After 10 times debugger finally runs. Getting throug this errors is really anoying, so please help me to fix it.
