Yocto init зависает на Banana Pi: как отладить?
в Yocto (ветка mickledore для poky и всех слоев) я собираю core-image-minimal дляMACHINE ?= "bananapi-m2-zero". Прошил на карту µSD, все запускается, но потом зависает где-то на уровне запуска 5. Мои вопросы:
- Какова лучшая стратегия отладки, которой мне следует следовать?
- Как лучше всего заставить inittab не создавать ничего, кроме последовательной консоли (чтобы я, надеюсь, получил рабочую отправную точку и мог активировать другие сценарии позже один за другим.)
- Как определить, зависает ли инициализирующий скрипт или что-то еще мешает войти? (Когда я беру SD-карту, ядро печатает жалобы, поэтому кажется, что оно работает.)
Я использую следующие слои:

Что я пробовал до сих пор: я сделал запись журналов на SD-карту, а не на виртуальный диск, ожидал новой информации, но было то же самое, что и на последовательной линии. Запустил собственный скрипт (отсоединенный с помощью &) в инициализирующем скрипте, ожидал, что он будет работать бесконечно, но получил только 4 отпечатка:
while (true)

echo "Hello World"
