Dear all,
I am trying to enable SPI1 and I2C on the BBB wireless which runs on Debian 10 and kernel 6.1.12-bone-rt-r15. The Debian image is the AM3358 Debian 10.3 2020-04-06 1GB SD console image from BeagleBoard.
If I understood correctly, to enable SPI, I have to add the corresponding DTBOs to the /boot/uEnv.txt. However, after adding the SPI dtbo, I still don’t see SPI showing up in /dev/ .
Although I2C is in /dev/, somehow I cannot initiate I2C communication in a program.
Here is the output from running /opt/scripts/tools# ./version.sh. Hopefully it helps a bit with identifying the issue.

Thank you in advance.
The script is reporting, you have a file named: /uEnv.txt, so /boot/uEnv.txt is being ignored…
Regards,
Thanks Robert! I’m sorry for not spotting that message 
It was obvious…
Indeed, after removing the extra uEnv.txt, I can use I2C now. However SPI still does not show up in /dev/.
This is the output from running version.sh again. Do you think the bb-cape-overlays version being too old could cause problems?
Thanks!

okay, this might take a seril port to debug, but looking above, do you see those:
UBOOT: Loaded Overlay:[BB-I2C1-00A0]
That comes from this magic: bb.org-overlays/src/arm/BB-I2C1-00A0.dts at master · beagleboard/bb.org-overlays · GitHub
/*
* Helper to show loaded overlays under: /proc/device-tree/chosen/overlays/
*/
fragment@0 {
target-path="/";
__overlay__ {
chosen {
overlays {
BB-I2C1-00A0 = __TIMESTAMP__;
};
};
};
};
Which is purely used to help us know that the overlay got properly loaded…
…
So, assuming /lib/firmware/BB-SPIDEV1-00A0.dtbo actually exists and u-boot loaded it? (check serial) it’s either missing that helper above or wasn’t loaded…
Edit, the above is still useful, but i bet, shows an awesome warning…
dmesg | grep -i spi
make sure you use a valid options now: src/arm/overlays/BB-SPIDEV0-00A0.dts · v6.1.x · BeagleBoard.org / BeagleBoard-DeviceTrees · GitLab
compatible = "rohm,dh2228fv";
Regards,
Thanks for the suggestion!
Indeed like you said, seems like uBoot didn’t load BB-SPIDEV1-00A0.dtbo. Here is the serial output from boot:
For the dmesg commend, nothing was returned. So I guess it confirmed that SPIDEV1 is not loaded.
Sorry I’m quite new to device trees. When you say to use a valid option, do you mean to change the compatible entry in SPIDEV1 and recompile it?

That’s also very very old, it didn’t go beyond uboot_overlay_addr3, in your serial log… don’t remember exactly when i added add4+…
sudo apt update
sudo apt install bb-u-boot-am335x-evm
sudo /opt/u-boot/bb-u-boot-am335x-evm/install.sh
Regards,
Ah so it’s the uBoot too old.
Yes after the update I do see spidev0.0 spidev0.1 under /dev/. Are the dot in the spidevs normal?
I thought it would be something like spidev1
Since I only added BB-SPIDEV1-00A0.dtbo in /boot/uEnv.txt, is it normal to have both spidev0.0 and spidev0.1 showing up?
Thanks!
Correct, we’ve always exported 2 modes for spidev, going way back to 3.8.x era… src/arm/overlays/BB-SPIDEV0-00A0.dts · v6.1.x · BeagleBoard.org / BeagleBoard-DeviceTrees · GitLab
If you look real close, one has the spi-cpha; flag enabled…
Why… well that was decided a long time ago, it’s just been that way forever…
Regards,
