Выполнил команду. Дата 15 мая 12:26, еще раз сохранил imx28-evk.dts

Выполните

make linux-rebuild

make xxx_config делать не нужно

Если вы не умеете менять .dts для сборки - вам это не поможет

Я бы, для начала, собрал mainline 4.19 и попробовал загрузить его по tftp

Может есть где то готовый настроенный .dts ?

Свой надо иметь :) В прошлый раз просто не скомпилировался .dtb из него, что видно по датам.

Да скомпилировать его отдельно и подсунуть при загрузке - судя по логам, там не FIT

Написал следующие команды:

cd /home/alexey/work/buildroot

make linux-rebuild

make

Извиняюсь за глупый вопрос, правильно ?

Я обычно собираю ядро отдельно, rootfs отдельно. Это чудо-тион умеет грузиться с NAND?

Ну вот, уже прогресс. Теперь можете приступать к запиливанию U-Boot, ядра и обоих DT под ваши нужды. Я бы U-Boot, ядро и DT оставил в NAND, а rootfs разместил целиком на SD-карте

Можно, но сначала напишите, в какой очередности хотите запускать периферию - будем потихоньку править dts.

Из очевидного - m25p80 лишний, не запускается ни один ethernet, девайс по имени sgtl5000 явно отсутствует.

2Alex_Golubev:

1. /proc/config.gz имеется в загруженной системе?

2. Toolchain для сборки - изнутри buildroot или свой?

1 Дисплей.

2 тачьскрин

3 USB HOST 

4 UART 

5 Попробуем TCP/IP. 

6 Может что еще. ну думаю дальше сам уже. 

В конце хочу написать инструкцию по шагам, может кому пригодится для старта как мне.

1 и 2 - после того, как ядро научитесь перекомпилировать.

3 - судя по логам, признаки жизни подает

4 - минимум две штуки есть.

5 - как уже сказал, надо оживить ethernet'ы. Судя по схеме - два Phy на одной шине MDIO. Как это оформляется в DT я уже тут писал в разделе FPGA-SoC.
