Other Parts Discussed in Thread: AM62L, SYSCONFIG,
Tool/software:
Hello,
I'm trying to test SPI comunication on AM62L EVM but I'm having trouble getting it to work. I've read similar threads and tried those solutions with no luck. I hope you can help me to check if there is anything wrong or missing in my procedure. I'm using the default kernel as starting point.
What I've done so far and some of my outputs:
1. Modified kernel configuration with menuconfig
Device Drivers --->
[*] SPI support
<*> User mode SPI device driver support
2. Modified device tree (k3-am62l3-evm.dts), using sysconfig tool output. I also changed all to INPUTS according to a suggestion on other thread, but none of the configurations worked.

3. Compiled Image, device tree and modules following this guide
* There was a warning that appeared on DT compilation. As far as I could search it shouldn't be a problem, but just in case:
make DTC_FLAGS=-@ ARCH=arm64 CROSS_COMPILE="$CROSS_COMPILE_64" ti/k3-am62l3-evm.dtb DTC arch/arm64/boot/dts/ti/k3-am62l3-evm.dtb arch/arm64/boot/dts/ti/k3-am62l.dtsi:101.30-112.5: Warning (simple_bus_reg): /bus@f0000/bus@43000000: simple-bus unit address format error, expected "b00000" also defined at arch/arm64/boot/dts/ti/k3-am62l-wakeup.dtsi:11.15-144.3
4. Installed Image, dtb into targetNFS/boot, and modules into targetNFS (I'm not using SD card as rootfs since I have another unresolved issue with it)

[ 364.705867] audit: type=1334 audit(1749769187.841:17): prog-id=19 op=LOAD
I crossed compiled spidev_test.c and tried:
root@am62lxx-evm:/home# sudo ./spidev_test -D /dev/spidev1.0 -v -p ABC spi mode: 0x0 bits per word: 8 max speed: 500000 Hz (500 kHz) TX | 41 42 43 __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ |ABC| RX | 00 00 00 __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ |...|
Apparently it works fine but there is no output on the pin headers. Also D0 and D1 are connected together with a jumper and there is no data on RX.
Oscilloscope probes are on CLK and CS0 (header pins 30 and 27) and D0 - D1 (pins 28 and 29) are connected together with a jumper to test loopback communication. I don't see any activity on any line. I've already double checked my probes and jumpers.
Here I got device tree configurations applied on the target. It seems good to me, but maybe I'm missing something:

Also, bit 18 is set in all registers.

Please let me know if there is anything else I can try.
Thanks in advance
