Fenix 1.0.11 Ubuntu 20.04.4 LTS Linux 5.17.0
I can’t use overlays to setup SPI, The log says:
Apply dtbo spi1
Failed to load '/dtb/amlogic/overlays/kvim3/spi1.dtbo'
Apply dtbo os08a10
Failed to load '/dtb/amlogic/overlays/kvim3/os08a10.dtbo'
Apply dtbo watchdog
Failed to load '/dtb/amlogic/overlays/kvim3/watchdog.dtbo'
For Real-Time demands, I can’t use 4.9 kernel. Because only the mainline can successfully patch RT-Patch.
Here comes a question, Is mainline support SPI?
By the way, I have two slave devices to communicate via SPI
So, Could it happen that spidev1.0
and spidev1.1
appear in /dev
for me to open?
How can I edit some DTS(I’m trying) or other files to make it work.
Please help me,Thanks
Or Is anyone can tell me mainline doesn’t support SPI yet for now?

@DylanMingan I will find time to test it and feedback there.
Thank you so much!!!
As a rookie in Linux, this has really tortured me for a long time. Now I’m very excited to hear that you start dealing with this problem. I’m waiting for your good news.

Is it possible to use SPI in mainland right now? @Frank
Weakly ask, is it possible to complete this function in a few months?
