See the top level README for information on where to find the schematic and programmers reference manual for the ARM processor on the raspberry pi. Also find information on how to load and run these programs. Same as blinker01 in the directory above, except the raspberry pi 2 has two leds one on gpio47 the other gpio35 Also note to make more room for ram the raspberry pi 2 uses a base address for peripherals of 0x3F000000 where the raspberry pi used 0x20000000. also note that for the raspberry pi 2 the arm file copied from the sd card to ram is kernel7.img the older raspberry pis still use kernel.img.
