3.1 Principle of operation
The firmware within the BDI handles the GDB request and accesses the target memory or registers
via the JTAG interface. There is no need for any debug software on the target system. After loading
the code via TFTP debugging can begin at the very first assembler statement.
Whenever the BDI system is powered-up the following sequence starts:
