Rockchip GMAC: полная настройка RGMII, RMII, SGMII и QSGMII

Применимость к ArmSoM

Это справочный материал по платформе Rockchip, а не отчёт об испытаниях ArmSoM. Адаптация требует проверки интерфейса Ethernet конкретной платы, PHY, питания, сброса, IOMUX, опорных частот и целевого SDK/BSP. Поддержка всех плат ArmSoM не предполагается. Аппаратная проверка не проводилась. Журналы, пропускная способность и временные результаты взяты из исходника, а не измерены на ArmSoM.

Обе версии — V1.4.0: 65 китайских и 68 английских страниц. Описаны 14 групп платформ: PX30, RK1808, RK3128, RK3228, RK3288, RK3328, RK3368, RK3399, RK3528, RK3562, RK3568, RK3588/RK3576, RV1108 и RV1126. В исходной таблице указаны «все версии» ядра; это обобщение оригинала, а не подтверждение применимости примеров к любому BSP или плате. Сохранены технические изменения: V1.1.0 добавляет RK3588, V1.2.0 — RK3528, V1.3.0 — RK3562, V1.4.0 — RK3576 по образцу RK3588. Китайская статья следует китайскому оригиналу; английская и русская — английскому. Все шесть рисунков извлечены из соответствующих оригинальных PDF.

Различия одной версии сохранены: §3.4.5 содержит phy-mode rmii в китайском, но RMII в английском; в §3.10.4 английская версия пропускает точки с запятой после двух дочерних узлов PHY; в §3.10.5 последняя группа выводов gmac0m0 — rgmiim1_rgmii_bus в китайском и rgmiim0_rgmii_bus в английском. Это не проверенные конфигурации для немедленной сборки. Знаки + — исходные отметки изменений; перед использованием нужна проверка целевого BSP. Технические значения не исправлялись молча.

Ниже приведены основные схемы соединений для режимов RGMII/RMII.

1. Режим RGMII

Обычно используется выходной тактовый сигнал PLL основного контроллера. Входной сигнал 125M от PHY является альтернативным вариантом.

1.1 PLL выдаёт 125M для TX_CLK, кварц 25M для PHY

PLL основного контроллера формирует тактовый сигнал TXCLK, а кварцевый резонатор — сигнал 25M для PHY.

Оригинальная схема подключения режима, EN p6

Оригинальная схема подключения режима: EN PDF p6.

1.2 PLL выдаёт 125M для TX_CLK, PLL 25M для PHY

PLL основного контроллера формирует тактовый сигнал TXCLK; сигнал 25M для PHY также поступает от основного контроллера.

Оригинальная схема подключения режима, EN p7

Оригинальная схема подключения режима: EN PDF p7.

1.3 вход TX_CLK 125M от PHY, PLL 25M для PHY

Тактовый сигнал TXCLK поступает от PHY, а сигнал 25M для PHY — от основного контроллера.

Оригинальная схема подключения режима, EN p8

Оригинальная схема подключения режима: EN PDF p8.

1.4 вход TX_CLK 125M от PHY, кварц 25M для PHY

Тактовый сигнал TXCLK поступает от PHY, а сигнал 25M для PHY формирует кварцевый резонатор.

2. Режим RMII

2.1 выход тактового сигнала RMII

Необходимый тактовый сигнал RMII формирует основной контроллер.

Оригинальная схема подключения режима, EN p10

Оригинальная схема подключения режима: EN PDF p10.

2.2 вход тактового сигнала RMII

Необходимый тактовый сигнал RMII формирует PHY.

Оригинальная схема подключения режима, EN p11

Оригинальная схема подключения режима: EN PDF p11.

Аналогично в режиме RMII кварцевый резонатор можно заменить выходным сигналом 25M основного контроллера.

3. Настройка режимов

Настройки разных режимов главным образом включают phy mode, тактирование и pinctrl. Эти параметры связаны и должны задаваться совместно, иначе интерфейс не будет работать. Ниже приведены примеры для разных микросхем на основе DTS плат из SDK. Особое внимание уделите изменениям, помеченным «+» внутри узла gmac в DTS.
