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

- default on the RPi 3. To enable the UART console, the following non-

- about the HDMI/usbkbd console.

- default option must be present in config.txt: enable_uart=1. This is

- At the time of writing, the VC FW requires a non-default option in
- config.txt to request the ARM CPU boot in 64-bit mode:
- arm_control=0x200
- The VC FW typically provides ARM "stub" code to set up the CPU and
- quiesce secondary SMP CPUs. This is not currently true in 64-bit
- mode. In order to boot U-Boot before the VC FW is enhanced, please
- see the commit description for the commit which added RPi3 support
- for a workaround. Since the instructions are temporary, they are not
- duplicated here. The VC FW enhancement is tracked in
- https://github.com/raspberrypi/firmware/issues/579.
- This option creates a build targetting the ARMv8/AArch64 ISA.
