I am now working with L3.10.17 on Freescale i.MX6soloSabreauto board(which with nor-flash m25p32 equipped).

When I run mxc_spi_test under unit_test folder,I always got Error:cannot open device (Maybe not present in your board?).

I know reason for this error is that the kernel has not create /dev/spidevB.C(B for bus num, C for chip select) node.

I read the device tree files and other related files,but I have not found any solution.


And then I tested with L3.0.35,the result is the same with L3.10.17.


Could you let me know why the kernel donnot create device node for spi-nor? And where to modify to reslove this problem.


Thank you!
