Status/Open Issues
==================
Although this configuration is not particualarly different from the
SAMV71-XULT board, my initial attempts to debug the board have not been
successful. The code is just not behaving correctly in excuting the first
few instructions after reset. I have very early realease boards and I am
suspected some tool/board issue: It appears that I write the code
correctly to FLASH and the GPNVM is configured so that the FLASH lies at
address 0x00000000, but trying to step through with AtmelStudio 7 results
in uninterpretble behavior. Using the Segger J-Link, I get errors trying
to reset and halt the board so I am unable to use that debugger either.
2015-11-30: The basic NSH configuration is function with serial console
via the EDBG VCOM and LED and buttons support. SDRAM and the HSMCI
SD card slot also appear to be fully functional.
WARNING: This README derives heavily from the SAMV71-XULT README file and
may still contain some logic that pertains only to that board. This is a

Where 0x28 is the address of TWI interface to the EDBG, 0x4e is the
address of the CP2100CP programmable PLL, and 0x57 and 0x5f are thei
addresses of the AT2 EEPROM (I am not sure what the other address,i
0x37, is as this writing).
