imx6q spi slave program change

413734891 — Thu, 16 May 2019 07:06:46 GMT

Hi, my linux kernel is 4.1.15， my pad is connected to DSP through SPI。Now I want my pad wors as SPI slave, but I don't know how to do. So I want to know: Do I need to rewrite a spi slave program and put it into the Linux kernel, or just modify the spi configuration register ? And how can I know the pad works which slave mode?

Hi 留杰付

first one can check ecspi errata and check patches with description

Chip Errata for the i.MX 6Dual/6Quad and i.MX 6DualPlus/6QuadPlus - IMX6DQCE

[PATCH RFC 0/5] *** SPI Slave mode support ***
