Web25. aug 2015 · Hello all, Since I am relatively new to Linux device trees I wanted to get some confirmation of my initial findings. I was wondering if 3wire SPI mode is supported for the Arria V board, Kernel 3.10_ltsi? I have tried to configure it as shown below and but always get the message “setup: unsupported mode bits 10” during bootup. If that appears correct is … Web26. apr 2024 · The Pi has limited hardware support for 3-wire. It's only supported on the auxiliary SPI. As far as I am aware the only software which supports this hardware mode is pigpio. The auxiliary SPI sends x bytes out on SDIO and then reads bytes from SDIO. E.g. you can send one byte and then receive 3 or send 5 bytes then receive 19. moira bumbacherWeb246行，该spi设备属于SPI子系统初始化时注册的那条叫“spi”的总线。 248行，设备模型方面的初始化，不说。回到spi_new_device函数，355至362行，是一些赋值，其中359行比较关键，设备名字拷贝，362行，之前说过了，设置为NULL。看364行spi_add_device函数的定义… moira canal fishing
