Raspberry Pi 4B CAN HAT support ?

B

blt2b

I got a Raspberry Pi 4B with a RS485 CAN HAT.
FreeBSD 14.0-RELEASE is working perfectly fine but I am not able to see / interact with my CAN HAT.. Is there a need to add some special parameters ? (I already added the ones from the documentation) or CAN HAT is not supported by FreeBSD ?

Thanks
 
Code: 
# dmesg | egrep -i can\|spi

Thanks Starcat for your findings !

So it is definitely not instantiated correctly as I don't have anything either on dmesg, /dev or ifconfig..

I am wondering if something is missing in /boot/efi/config.txt

I tried that :
[all] arm_64bit=1 dtparam=audio=on,i2c_arm=on,spi=on dtoverlay=mmc dtoverlay=disable-bt dtoverlay=mcp2515-can0,oscillator=8000000,interrupt=25,spimaxfrequency=1000000 device_tree_address=0x4000 kernel=u-boot.bin [pi4] hdmi_safe=1 armstub=armstub8-gic.bin enable_uart=1
 
Thanks tingo .

I added both
rc_debug="YES" rc_info="YES"
to my /etc/rc.conf, here is the result :

As you can see I am trying 15.0 to see if I would had more chance, but got the same behavior with 14.0-RELEASE
 
Have you built and installed port sysutils/rpi-firmware?

It contains device tree blob overlay files:
share/rpi-firmware/overlays/mcp2515-can0.dtbo
share/rpi-firmware/overlays/mcp2515-can1.dtbo
share/rpi-firmware/overlays/mcp2515.dtbo
 
Thanks Starcat I can't believe I missed that ! I thought that this would had been included into the RPI build...

I added it and did a

cp -pr /usr/local/share/rpi-firmware/* /boot/msdos/ cp /boot/msdos/config_rpi4.txt /boot/msdos/config.txt

and also added

enable_uart=1 dtoverlay=mcp2515-can0,oscillator=8000000,interrupt=25,spimaxfrequency=1000000

But nothing changed (dmesg, /dev, ifconfig)
 
You're welcome! According to the Waveshare wiki, the following line would also need to be added to config.txt:
Code: 
dtparam=spi=on
Hope that helps.
 
Thanks, yes I also tested that, that is my current (non working) config.txt :

cat /boot/efi/config.txt arm_64bit=1 dtoverlay=disable-bt dtoverlay=mmc device_tree_address=0x4000 kernel=u-boot.bin armstub=armstub8-gic.bin hdmi_safe=1 enable_uart=1 dtparam=spi=on dtoverlay=mcp2515-can0,oscillator=12000000,interrupt=25,spimaxfrequency=2000000
 
I have also developed a sudden interest in CAN buses (for big diesel engines). Quick question about debugging your hat problem: Have you tried booting Debian? It might tell you whether the problem is hardware or (FreeBSD-) software.

I googled this with these search terms. "freebsd mcp2515-can0" Note, that a DTS file should work with any operating system. So you may be able to copy and paste into your own device tree files (script & binary blob) Wish you good luck, and hope to see a post titled "SOLVED mcp2515-can0" .

RV5 https://forum.rvspace.org/t/can-bus-not-exposed/2517/13 post with ideas, pictures, Yes not Raspberry Pi FreeBSD, but might learn from this post.

Yes, looking for your FreeBSD 14.0 support information to CAN bus on a raspberry pi 4B. I have used an expensive tool to read data from a Cummins NT Diesel engine in an older Freightliner Semi Truck. Looking for future conversations, cell phone pictures, schematics diagrams, & configuration files that are tested to work. We all benefit, from your sharing information here. Fred
https://www.can-cia.org/can-knowledge/ Here is introductory CAN BUS webpage from CAN In Automation group ( CIA ).
The CAN knowledge webpages describe several CAN physical layer options. Additionally, these webpages also contain technical descriptions about CANopen CC and CANopen FD as well as other standardized CAN-based higher-layers.

Hope others share USEFUL Controller Area Network CAN information Fred

I tried Alpine Linux and was able to see the CAN as a serial device and was able to interact with it
