Developing the Configuration File
The JTAG vendor will likely already have a register file for the processor
ARM920, PPC8241, etc.
Your task will be to develop the board configuration file
There may be a configuration file for the reference board that you can use as a starting point
The configuration file is essentially a script of commands to initialize the target board
You keep working on it until you can initialize memory
Once memory is on-line, you should then be able to write values into memory via the JTAG that can be read back
Then, enhance the configuration to initialize other peripherals
