Support for all ARM1176-/BCM2835-based Raspberry Pi variants, such as
|
|
|
|
|
the A, A+, B, B+, Compute Module, and Zero. This option cannot
|
|
|
|
|
support BCM2836/BCM2837-based Raspberry Pis such as the RPi 2 and
|
|
|
|
|
RPi 3 due to different peripheral address maps.
|
|
|
|
|
|
|
|
|
|
This option creates a build targetting the ARM1176 ISA.

Support for all BCM2836-based Raspberry Pi variants, such as
|
|
|
|
|
the RPi 2 model B.
|
|
|

|
|

|
|
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
