| 26 | RPi 3 due to different peripheral address maps. |

| 37 | |
| 38 | This option also supports BCM2837-based variants such as the RPi 3 |
| 39 | Model B, when run in 32-bit mode, provided you have configured the |
| 40 | VideoCore firmware to select the PL011 UART for the console by: |
| 41 | a) config.txt should contain dtoverlay=pi3-miniuart-bt. |
| 42 | b) You should run the following to tell the VC FW to process DT when |
| 43 | booting, and copy u-boot.bin.img (rather than u-boot.bin) to the SD |
| 44 | card as the kernel image: |
| 45 | |
