This recipe will allow yocto images to support configuring and updating the bootloader on Raspberry Pi 4 boards. So far this recipe just includes the commands and firmware with no automation for updates. Note that this depends on nvmem-rmem support either built into the kernel or as a module. If that is not part of the kernel the scripts will error out suggesting that the vcgencmd command from the userland package is missing. Whilst using vcgencmd from the userland package does work, it would lead to a conflict with the mesa backend for graphics, so using the kernel interface is recommended.

Subject: [PATCH] Fix rpi-eeprom-update when using busybox find
|
|
|
|
The busybox implementation of find does not detect recursive nested
|
|
symlinks, this results in it finding multiple instances of of_node
|
|
matching -samefile, the result of which then fails the -e path test.
|
|
|
|
The of_node symlink we're tyring to find should match the path
|
|
/sys/bus/nvmem/devices/*/of_node so just limit the find depth to 3 as
|
|
there's no point searching deeper than that.
