Martin Petrašovský Posted March 5 Posted March 5 (edited) 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 Armbian 25.2.2 Bookworm Minimal / IOT image, this problem arises. Could someone please assist me in resolving this problem? Edited March 5 by Martin Petrašovský 0 Quote
brentr Posted March 5 Posted March 5 I will have a look at this over the weekend. Could you provide source code for your test case? 0 Quote
