Hi, I'm using Armbian Bookworm for my Orangepi 4 LTS (RK3399). In the setting section (Armbian-config), I did enable SPI, however after rebooting, there is no spidev in the /dev/ directory. I hope you can help me. Also I need usart2B, I know its pins are available in this board but I don't see any related configuration or options.

I'm sorry, I thought it might be relevant to forum orange pi 5 plus! The details of the board is: Orange Pi 5 Plus Chip & Architecture: Rockchip RK3588- 8-Core 64-bit Processor Quadcore A76 + Quadcore A55 Well, I'm not an expert in kernels but I need a real-time communication with FPGA so the SPI driver must be real-time. by the way my o.s. is Armbian 24.2.1- Bookworm Legacy 5.10.160-xfce Desktop and the result of "uname -a" is: Linux orangepi5-plus 5.10.160-rt89+ #8 SMP PREEMPT_RT Sun Apr 14 23:02:59 CST 2024 aarch64 GNU/Linux And I wanna use spidev0.1 and the minimum desired rate is 5 MHz for SPI.

Hi guys We're trying to run SPI with Linuxcnc. But sometimes SPI latency with other hardware (FPGA) gets big. The operating system is armbian and I could install a real-time kernel on it so I know it shouldn't be real-time issue with kernel. We've noticed that it might be the spidev driver issue that is not real-time. And now we're gonna communicate with low-level SPI. Bit I dont know how? can any one please help me?
