SPI Slave Support. Due to the nature of SPI slave (simultaneous transmit and receive, while everything runs at the pace of the master), it has hard real-time requirements: once an SPI transfer is started by the SPI master, a software SPI slave must have prepared all data to be sent back to the SPI master.

In the same way, SPI slaves will only rarely support any kind of automatic discovery/enumeration protocol. The tree of slave devices accessible from a given SPI master will normally be set up manually, with configuration tables.

So far, Linux always assumed the master role. In v4.13, Linux finally gained slave support. In this presentation, Geert will talk about adding SPI slave mode support to the existing SPI subsystem, and using a Linux system as an SPI slave. He will show what makes SPI special, and cover possible use cases and limitations of Linux-based SPI slave ...

Mar 19, 2019 · 1. As CONFIG_SPI_SLAVE is added in kernel from kernel version V4.13-rc1 and I am using the older kernel version V4.1.15 - do I need to add any patch in the kernel (to support the slave mode in the kernel). In case we do have to add patch - can you please share the patch.Reviews: 2

On our AT91SAM9 based devices a Linux driver is provided. As most peripheral chips are slaves this driver only works in master mode. To connect a spi chip four signals are needed: CLK, MISO (master in, slave out), MOSI (master out, slave in) and a chipselect. This how-to describes how to configure and use the SPI user-mode device driver (spi-dev).

Jul 23, 2015 · I want to use the mcspi0 as spi slave. As it is not currently supported in kernel, I modified the omap2_mcspi.c to support slave mode I need to enable the SPI interrupts RX receive of data. when I enable the interrupts OMAP2_MCSPI_IRQENABLE_RX0_FULL and OMAP2_MCSPI_IRQENABLE_RX0_OVERFLOW I found ...

At this time, only “master” side interfaces are supported, where Linux talks to SPI peripherals and does not implement such a peripheral itself. (Interfaces to support implementing SPI slaves would necessarily look different.) The programming interface is structured …
