r32180 Thursday 18th September, 2014 at 15:34:34 UTC by David Haywood
make r2dx_v33 2 sets for now, with different eeprom, the codepath it takes (R2 or RDX) depends on the content of the EEPROM, I haven't found a switching mechanism (there appears to be code in the ROM for booting with buttons pressed, but it looks broken to me)
