due to a self designed board for the pi I need to change the default pin configuration during boot / startup. I need to drive some outputs to high directly after powering the pi.
I decided to use a user provided device tree blob file as it is described here: https://www.raspberrypi.org/documentati ... uration.md
For test issues I downloaded the sample device tree at the bottom of the page, compiled it with
and it copied to the /boot/ partition.
Code: Select all
dtc -I dts -O dtb -o /boot/dt-blob.bin dt-blob.dts
When I now try to reboot the pi the green led lights up shortly for one time and stays off afterwards. -> No no system startup
Am I doing anything wrong? Do I have to do some additional configuration?
