Hi,
We have applied the patch provided on below link to enable spi slave mode .
How to support spi slave in kernel4.1.15 & imx6?
Spi driver is probed successfully , When we connect is to spi master device and spi master device send data nothing is observed in dmesg .
From hardware prospective we have verified that spi-master data and clock properly send the spi slave line .
Our actual requirement is to make imx6 as slave and microcontroller as master which sent data on spi line .We need read and write through the
spi-slave (ie imx6 ).Any suggestion related to this please provide the same .
Thanks
our BSP is not support SPI slave mode.
Only kernel 4.15 and 4.16 from mainline supports it.
In order to use SPI slave in these kernels the "spi-slave" property needs to be passed in the devicetree as explained at:
