Я создаю свой первый релиз yocto.
Все пакеты собраны хорошо, и я могу собрать свои dts.На самом деле у меня много dtb в папке с изображениями.
Это моя конфигурация сборки.

НаВ момент, когда я использую dd для прошивки содержимого этого архива:
core-image-base-pico-imx6ul-itl.sdcard.bz2
u-boot использует это дерево устройств:
imx6ul-pico-qca_pi.dts
Но я хочу вот это:
imx6ul-pico_pi.dtb
Можете ли вы помочь мне исправить DTS?Я не могу найти учебник / документацию для этого сценария.
