I am trying to use the SPI Bus on the Devkit but am not able to get it working. I followed the steps here:
The spidev module is loaded and I tried to send bytes via the python spidev library but I am not seeing any activity on the clk line using my oscilloscope.
spi = spidev.SpiDev()
to_send = [0x01, 0x02, 0x03]
Could you try spidev_test utility.
Any update? Is this still an issue on you end?
I have same question.
The SPI1 is spidev0.0?
I modify the dts like below.
status = "okay"; // Before change: "disable"
compatible = "spidev";
reg = <0>;
Should I modify the pinmux value??
We are still having this issue. I haven’t tried the new Jetpack yet though.
Have a reference to below link to check the pinmux.
I have my pinmux correct according to that thread but I am still not seeing anything on the clock or data lines…
