-
-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.

-
-specifically for a forum question, self modifying code if you will,
-writes instructions to ram then branches to that code.  in this case
-essentially the same blinker01 example just some asm that is loaded
-by the running program then branched to.
-
-blinker.s is the ASM program that does the blinking and blinker01.c
-just writes those instrucions to ram and executes them.  blinker.list
-once assembled and dumped shows the list of instructions.  naturally
-you have to start at an address that is aligned on a 32 bit boundary,
-any address that has ram behind it not being used by the program
-loading nor the gpu, should work.

-A+ and B+ have two leds one on gpio47 the other gpio35.

-I tested this on an A+.  I probably have a B+ around somewhere, but
-not sure where.  The A+ does appear to have two leds and they are both

-(0x20000000) likely to make room for more ram but who knows.

-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 blinker05 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.
-
-A new develoment late 2015 is that the raspberry pi start.elf code now
-puts the rpi 2 in HYP mode.  The two changes I needed to make were
-to set the HVBAR, might as well set it to 0x00008000 rather than copy
-the vector table to 0x00000000.  so the lines up front that copied
-the vector table are now replaced with remapping.
-
-    mov r0,#0x8000
-    MCR p15, 4, r0, c12, c0, 0
-
-The other change being you are supposed to return from hypervisor
-exceptions using the eret instruction.
-
-    ;@subs pc,lr,#4
-    eret
-
-For the purpose of this example my desire is to use the stock
-bootcode.bin and start.elf from the raspberry pi foundation, as well as
-running without a config.txt, so I have not gone backward to older
-files to see if there are any nuances or changes for the rpi2 with
-respect to exceptions (irq in this case).  My guess is if they leave
-you in supervisor mode instead of hypervisor mode, then it may work
-just like it used to.
