here is a copy paste from the creators of the board:
Absolutely, the chip is supported and that is why it was relatively easy to get Linux to boot by using that board as a starting point. However, that is for a particular development board built around the AT91SAM9M10 which differs in some ways with Lophilo: we don't have NAND flash, the GPIO pins we use are different, MPU features enabled/disabled are different.
You can see some of the changes here:https://github.com/Lophilo/linux/commit ... m10g45ek.c
The chip in that board is the same, but the board is not the same as our board.
The difficulty for us is to modify that particular board configuration to fit with our particular hardware instance which is not connected exactly in the same way as the development board AND add support for our reconfigurable hardware (the FPGA).
