прочел похожие темы и проверил, у меня заполнен раздел dev/root на 100%

Добрый день.
Да, поведение для отсктствия места - характерное.
Советую переместить что-нибудь на другой раздел.

А что можно переместить? у меня только Docker установлен.

Докер использует много места для снимков. Можно попробовать перенести всю его папку.
А так

df -h -d 2 /

Вот сегодня человек писал на хабре: Wirenboard — переход со stretch на bullseye / Хабр
Может вам поможет.

должно сработать думаю, спасибо большое

а может вы подскажете, место в root как то можно почистить? а то там всего 1 гиг, и по умолчанию системой занято 55%…

В вопросе относительно непосредственно контроллера не подскажу. Я себе его только заказ и жду когда приедет. Могу только как опытный пользователь линукса подсказать.
Вот пример инструкции Как переместить домашний каталог на новый раздел или диск в Linux

Достаточно пакет поставить: Wb debian stretch. apt update - #2 от пользователя BrainRoot
Но тут видимо factory reset сделан на какой-то старый образ.

home и так симлинком на другом разделе. Но вообще - советую на testing идти сразу, в нем размер корня вдвое больше. Ну и до релиза осталось совсем чуть.

как перейти на тестинг с увеличенным размером корня? wb-release -t testing не прибавил места
root@wirenboard-AMERIEJQ:~# df -h

Только FACTORYRESET с USB устройства.

я сделал сброс до заводских настроек, через кнопку fw

Как следует из документацции - это сброс именно на заводские установки.

так как перейти на тестинг? с 2гигами корня?

https://wirenboard.com/wiki/Wiren_Board_7_Firmware_Update#Прошивка_с_помощью_USB-флешки_или_карты_Micro-SD
используя latest.fit из ветки testing

а просто через web интерфейс не получится?

Нет.
