I have my 4 channels hooked up, in this order, to CS/ MISO MOSI and CLK on an active system using SPI bus.
I am able to trigger on the CS/ by using Edge triggering and falling edge and can see all the SPI signals I'm monitoring on this triggering.
However, the SPI triggering is very fussy. I had it working at one point, with the trigger set to SPI, the event to trigger on set to CS, the CS channel set to 1, and the mode set to "low enable" (from high to low to high again in the little icon). I also have the SDA channel set to channel 3 (my MOSI channel) and clock set to channel 4, and data set to XXXXXXXX (set to 8 bit data). I was making changes to try and trigger on specific data, which was not working for me for some reason. But it seems to have just stopped working even with data set to XXXXXXXX and nothing I do will get it to trigger again. Going back to Edge trigger, it triggers on channel 1 falling edge every time I expect it to. But the SPI triggering is being very stubborn. I think I've gone through all the settings and they seem correct.
I've checked that the trigger level in all of the channels, particularly, the CS/ (channel 1) is within proper range of the signal going from high to low.
Is there anything else I need to check for or be aware of that isn't mentioned in the manual?
