Hi,
I have problem with the driver. I'm not sure where the problem is.
Without calling sspi first, sf probe doesn't work. I guess driver
doesn't bind.
The output is:
=> sf probe
Invalid chip select 0:0 (err=-19)
Failed to initialize SPI flash at 0:0
Maybe I'm missing something?
Regards,
Stefan Mavrodiev
