Gullik Posted July 30, 2019 Share Posted July 30, 2019 I seem to have lost the SPI while versions have changed.

Gullik Posted July 30, 2019 Share Posted July 30, 2019 Hmmm.... Dumping the contents of the overlay file, /boot/dtb/overlay/sun8i-h3-spi-spidev.dtbo there ARE commands for the spi, but these are disabled. So, would it make more sense to have possible conflicting devices disabled ( as of now ) and the overlay file enabling selected, by the armbianEnv.txt mechanism?

Gullik Posted July 30, 2019 Share Posted July 30, 2019 So, boldly decompiled the spi-spidev dtbo, edited the dts to enable spi's, compiled back, replaced the dtbo, rebooted.... Nah....did not work....so obviously my brain did not filter out the correct structure of this.... No trace of anything interesting in dmesg.....

Gullik Posted July 30, 2019 Share Posted July 30, 2019 Thanks, That's right, but bus=1 does not create any spi device either....so it is something more fundamental... there is a ko named spidev, but modprobe does not make any change either....

No needs to do "modprobe", if loading overlay succeed, module will be loaded automatically. During early boot, using USB-TTL Serial dongle on debug port, what do you see when overlay is loaded and applying fixup script ? 0 Quote Link to comment Share on other sites More sharing options...

You don't have to change that, the fixup script will take care of applying an "okay" to the specified "param_spidev_spi_bus=1". 8 minutes ago, Gullik said: libfdt fdt_path_offset() returned FDT_ERR_NOTFOUND That is the error which seem to be the cause of the problem...

Gullik Posted July 31, 2019 Share Posted July 31, 2019 Thank you very much martinayotte, that worked like a charm :-) I misspelled spi_spidev at first, and got the same error, I might try the other image again, and triple verify spelling, something nonprintable?? anyway, the debian buster image is perfect for my use, and once the keyword was right it behaved exactly as documented / per your instructions.

Gullik Posted July 31, 2019 Share Posted July 31, 2019 Hi again, No, first time I tried ( when it failed ) I surely did a cut'n'paste from the web into armbianEnv.txt with these parameters. This time with the image you pointed me at, I wrote overlays=spi_spidev usbhost2 usbhost3 instead of overlays=spi-spidev usbhost2 usbhost3 by manual editing. Then before I posted the results (fail) , I double-checked, and found the mistake. After that all worked as expected. This lead me to believe that I *might* get a good result if I test again and re-edit the Env.txt, I cannot understand why it did not work as described, I guess I will do that and post again, just to close this issue properly If that fails, then there *is* an issue with the OS image I used. I have not observed anything else wrong with that image though. But Debian Buster is fine with me. Regards & Thanx Gullik 0 Quote Link to comment Share on other sites More sharing options...
anton.miroshnichenko Posted November 13, 2020 Share Posted November 13, 2020 Hi, guys Sorry for disrupting from the main theme, my question is also about SPI. Could you please give me an advice on how to setup W5500 Ethernet board on Armbian. I created thread for this.
