I tried to compile and insert in Mageia Linux 5.15.23-desktop-1.mga8 and an old computer with Debian Linux too. The Debian could compile and start /dev/spidev0.0-2 auto, but Mageia doesn't creates spidev devices.

`make

I can create it manually echo spidev > /sys/bus/spi/devices/spiB.C/driver_override echo spiB.C > /sys/bus/spi/drivers/spidev/bind

https://www.kernel.org/doc/html/latest/spi/spidev.html

And now I found: https://github.com/dimich-dmb/spi-ch341-usb#using-spi-slaves

Although I can compile and load driver, there is some error maybe I did something not well, but I cannot access anything on spidev0.0 with:

I can connect AT25DF321A to ch341a-SPIinterface and flashrom can read/write it on its builtin spi (ch341_spi) but no flash found on linux_spi:dev=/dev/spidev0.0. I tried to read id from C but debian always read FF FF FF FF, Mageia gives error. I tried avrdude mod with linuxspi, but couldn't found atmel chips on both Linuxes above.

Can anybody help which device/ic works and how to access it through this spi-dev driver?
