Пора пощупать новую игрушку
Содержание |
[править] Вводные
В комплекте идет блок питания на 12 В. Питание возможно как от него, так и от USB OTG.
Стартер-кит поставляется с микро-SD флеш-картой, содержащей два раздела - boot и debian rootfs. Попробуем поработать с этим bsp. На плате bootsel есть переключатель источника загрузки - SD или QSPI. Выбираем SD.
В качестве интерфейса с внешним миром имеем Ethernet, достучаться до которого с ходу не получилось, и RS-USB в виде разъема USB B-type. При подключении USB к PC udev добавляет /dev/ttyUSB0
, через который с помощью ckermit мы можем получить терминал. Для этого воспользуемся традиционным скриптом:
set line /dev/ttyUSB0
set FLOW none
set speed 115200
set serial 8n1
SET CARRIER-WATCH Off
connect
Не забываем chmod +x
.
После запуска скрипта имеем приветственное окно Debian с запросом логина и пароля:
Connecting to /dev/ttyUSB0, speed 115200
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.

Прокинуть ssh до 172.20.2.162 не удается, пинг не идет, nmap утверждает, что все порты закрыты.
[править] Установка static IP
Добавляем в /etc/network/interfaces
:
iface eth0 inet static
address 192.168.0.156
netmask 255.255.255.0
gateway 192.168.0.1
Даем команду на рестарт сетевых интерфейсов:
