I am working on a project that was using the 3.10-ltsi kernel. We have our system configured with two soft SPI interfaces through the FPGA. These soft SPIs are the free SPI cores in Quartus and then have the kernel configured with Altera SPI and Designware SPIs.
I have tried to update the system and with that have brought the kernel up to 4.1-ltsi. Through the device tree we have spidev configured for these ports. The kernel builds and everything seems to function except for these SPI cores. They seem to load and enumerate correctly. I am able to open the interface but when I try to do a transfer across them, I get an error for an invalid ioctl - this worked just fine with the previous 3.10-ltsi kernel. Has something changed where this will no longer work? Thanks. martin. _______________________________________________ Rfi mailing list [email protected] http://lists.rocketboards.org/cgi-bin/mailman/listinfo/rfi
