See the top level README for information on where to find documentation
|
|
for the raspberry pi and the ARM processor inside. Also find information
|
|
on how to load and run these programs.
|
|
|
|
This example is for the pi2, see other directories for other flavors
|
|
of raspberry pi.
|
|
|
|
Investigating/confirming what other folks have already found.

|
The MPIDR for the four cores are
|
|
|
|
80000F00
|
|
80000F01
|
|
80000F02
|
|
80000F03
|
|
|
|
We can use the lower nibble to sort them on boot (they all start
|
|
presumably at the same time, at the same entry point).
|
|
|
|
This config.txt is required in the same root directory where kernel7.img
|
|
lives.
|
|
|
|
kernel_old=1
|
|
disable_commandline_tags=1
|
|
|
|
The first line tells the start.elf bootloader to not boot from 0x8000
|
|
but instead from 0x0000, the second line says please do not trash
|
|
the first few hundred bytes with ATAG or device tree information.
|
|
Without that second line it loads kernel7.img then writes the ATAG
|
|
information assuming you have left a gap and branched over.
