I am experiencing an issue with my Rock Pi S. When using SPI1, I am not observing any CLK output signal on pin GPIO3_B3, which I have verified with an oscilloscope. Other signals such as MOSI, MISO, and CS are functioning correctly. I have found that this issue does not occur in the older kernel 4.4.143-65-rockchip-g58431d38f8f3. However, when using the latest image rock-pi-s_debian_bookworm_cli_b40, this problem arises. I have also observed the same issue when using the Armbian distribution.
