small atmel SAM S70 (300MHz cortex-M7) based dev board.
similar to the arduino due, except super-mega-turbocharged.
it is not quite right, but enough is working to boot OS/J5
bossac successfully hacked.
blinky.c successfully loaded.
LED is blinking!
board appears to work.
the SAM-BA boot rom runs, the usb port is recognized,
I can manually connect and enter cryptic SAM-BA commands.
chip is not supported by bossac though, so cannot program it, yet.
% emacs bossac.cpp
board is not finished yet, and there is still a little space on the board.
the SAM E70 has a compatible pinout and has ethernet.
is wired ethernet interesting?
I was looking for a small fast ARM board, with a high-speed (480MHz) USB.
