Hello everyone!
I'm trying to use a small SPI LED screen with my ROC-RK3328-CC.
I've scoured all over this website as well as the internet for information on enabling SPI on my ROC-RK3328-CC (libre renegade), and I'm sorry to say after trying so many things, I still cannot get it enabled.
I'm currently using this image: Armbian_19.11.7_Renegade_buster_current_5.4.8.img
I've added the following 2 lines to /boot/armbienEnv.txt
overlays=spi-spidev
param_spidev_spi_bus=0
and after reboot, nothing.
nothing for dmesg|grep spi
and no spidev devices in /dev
I've also tried manually changing status to "okay" for fragment@1 and fragment@2 within the dtbo, but still nothing.
Did I miss a step in the process of enabling this device tree overlay?
I read through the armbiean device tree overlay documentation online and in my overlay folder, but can't seem to figure out what else I might need to do to enable SPI
one thing I'm not sure about his how to get detailed u-boot logging like I see so many people post on this forum.
is there a file which this gets logged to? Is there a flag I need to set somewhere to enable u-boot logging to a file?
Any advice would be much appreciated.
Thanks for your time
