Здравствуйте!
Имеется CAN-BUS модуль MCP2515, подключается по SPI. Собрал ядро с поддержкой CAN-BUS и модуль
mcp251xВсе модуля (
can, can-dev, can-bcm, can-gw, mcp251x ) загружаются без ошибок, но интерфейс
can0 в системе не появляется. ( Подключение MCP2515 по мотивам
здесь и
здесь).
В комментариях исходника mcp251x.c сказано о ручной инициализации устройства
Your platform definition file should specify something like:
*
* static struct mcp251x_platform_data mcp251x_info = {
* .oscillator_frequency = 8000000,
* .board_specific_setup = &mcp251x_setup,
* .power_enable = mcp251x_power_enable,
* .transceiver_enable = NULL,
* };
*
* static struct spi_board_info spi_board_info[] = {
* {
* .modalias = "mcp2510",
* // or "mcp2515" depending on your controller
* .platform_data = &mcp251x_info,
* .irq = IRQ_EINT13,
* .max_speed_hz = 2*1000*1000,
* .chip_select = 2,
* },
* };
*
* Please see mcp251x.h for a description of the fields in
* struct mcp251x_platform_data.
*
Если я вставляю этот код в
mcp251x.c, ядро не собирается

Подскажите решение.
