SPI0 in BeagleV

Hello Community. Trying to workout SPI connection between Beagle and the ESP32 using SPI0. I have managed to expose the spidev0.0 using this guide: beagle.md · GitHub However i am unable to make any communication to esp32. dmesg logs show that the SPI0 is enabled. What could be the problem?

A little sparse on information, but credits for formatting! :+1:

How exactly are you testing?

Have you hooked up a Scope or digital probe to the pins in question,
to see if you get any twiddles when you “test” ?

Also, please make sure your current Gateware is connected where you think it is…

@lranders I am using an oscilloscope to monitor the SPI pins. I am not getting any twiddles while testing. I am using the Default Gateware. The SPI0 pins i am connected to are from the datasheet:

I guess I’ll ask again:

How exactly are you “testing” this?
Describe your test method.

Also, are you just looking at CS or are you checking SCLK and MOSI too?

Yes, so i have SCK and MOSI hooked to the scope to check for any activity. For CS i am using a multimeter to check since the scope i have is 2 channel. And i am not seeing anything going on. This is how i am testing. I hope this is more clear
