I'm not sure how to enable SPI in openSUSE Leap 43.3. I've changed the config.txt file and added "dtparam=spi=on", this has however no affect on the hardware. The same steps are working in Raspbian.
#> cat /proc/device-tree/soc/spi@7e204000/status disabled
Any ideas?
Please see my examples linked from the 40-pin connector on the HCL Wiki page.
Hmmm, I've digged through the wiki last night, but I was unable to find it. Could you post the link here?
Since we use U-Boot, such external Raspberry Pi examples won't work and you should use U-Boot's fdt apply command instead.
Intressting, I'm still trying to understand the whole boot process and at which time which component is loaded and can be modified. I thought the config.txt is loaded directly before u-boot and therefore SPI gets activated via that dtparam switch. So I have to get my head around the whole EFI boot.
