Hi,
is there a driver for HPS SPI slave controllers available in the Linux kernel? I thought the spis0 and spis1 modules at 0xFFE02000 and 0xFFE03000 base addresses in the Cyclone V HPS. I am not able to find anything about using these HW blocks under Linux.
HI!!
bad news! sorry! But spi slave controllers under linux are not yet supported!
I read it on : https://www.kernel.org/doc/Documentation/spi/spi-summary
"…This document (and Linux) currently only supports the master
side of SPI interactions…"
I think you have to write the drivers your self!
Or somebody else!! Ideas??? good news???
bye
