Confirmed.

The distcheck.lua script didn't get that far. It failed earlier with

i2ctest.c:(.text+0x4a4): undefined reference to `NutI2cMasterTransceive'

It's not that easy here. Actually that patch isn't fully correct for the

ATmega256x.

The AT91R40X may use additional external memory for code.
