Also find information +on how to load and run these programs. + +These examples are for the pi zero, see other directories for other +flavors of raspberry pi. The raspberry pi family is more similar than +different, but I have decided it is easier to manage by grouping the +examples by board type. + +The pi zero is similar to the original pi but overclocked and they +removed much of the stuff on the board to get things to make it smaller +and significantly lower cost. I think this was a direct response to the +getchip.com product. I wonder if they will actually continue production. + +My preferred way to run examples is to use my bootloader07 kernel.img on +the board with an ftdi usb to uart board or cable. I also solder a +momentary pushbutton on the RUN pins, which is basically a board reset. +There are ways to do this without soldering, pins you can push in rather +than solder. + +Once the sd card is in with bootloader07, press reset, download the +intel hex (.hex) version of the program I want to run. Press 'g' to go. +Repeat as necessary. + +Or you can copy the blinker01.bin file to the kernel.img file on your +sd card, replace the sd card and turn the power on.
