Nick Garnett did a port for ecoscentric, and we agreed that a seperate port will be cleaner as there are quite a few nigling differences between the uC's. There is however speculation that the a1 and a2 will be discontinued in the near future so yes, it seems more pratical to create its own variant.

Ok, just step by step to see if I uderstand you correctly. I am currently running the redboot elf image direct from ram using the Sam-ice JTAG device. 
Now I must build the kernel template I presume. 
When this is done, I must build the tm_basic test using the generated files from the last build and load the executable using redboot with its load with ymodem command.
The basic test should now be able to execute, or is there a better way.
