2-Channel CAN-BUS(FD) Shield installation failure PI 4

Products & Technology Shields
#1

Hi all,



I got a 2-Channel CAN-BUS(FD) Shield. Sadly the installation doesn’t work on my PI 4 with the actual Raspbian image. Please find the log down below.

Has anybody successfully installed this shield? Which image did you use?



Thanks in advance



Shaun

Hi Shawn,



I am using the CAN-BUS shield V2.0 on an arduino and I was able to get the software to load using the code found below.



<LINK_TEXT text=“https://github.com/AppSaloon/ecu-can-bu … cu-sim.ino”>https://github.com/AppSaloon/ecu-can-bus-simulator/blob/master/Seeedlib-ecu-sim/Seeedlib-ecu-sim.ino</LINK_TEXT>.



Note: If you get an INIT error should change the MCP_CAN CAN() value to 9 instead of 10.



Let me know how that works out for you



—

</s>const int SPI_CS_PIN = 9; MCP_CAN CAN(SPI_CS_PIN); // Set CS to pin 9<e>

Same here with a RPi4

Did anyone find a solution?

#4

I am having the same issue, tried so many things. I have built from many different sources I have found on the web with no success.

I was told by seeed that it would work with PI 4.

Wondering if anyone else has found a solution?

#5

Hi there

I was successful when I use the latest raspberry’s OS :smiley:

#6

Latest one as per https://www.raspberrypi.org/downloads/raspbian/ is:



Raspbian Buster with desktop

Image with desktop based on Debian Buster

Version: September 2019

Release date: 2019-09-26

Kernel version: 4.19



which is the one I’m using and which I did update/upgrade - so assumably it’s the latest one.



Which one did you use ?

#7

The hint from tomright here seems to work on a RPi3, still no luck on RPI4 though.

0. Go through failing Seeed procedure

  1. navigate to ~/pi-hats/CAN-HAT
  2. make
  3. make install
  4. sudo modprobe mcp25xxfd-can
  5. reboot
  6. dmesg | grep spi



    should give you:



    [ 5.399392] mcp25xxfd spi0.0: MCP2517 successfully initialized.

    [ 5.438864] mcp25xxfd spi1.0: MCP2517 successfully initialized.
#8

Got it working on RPI4:


  1. install Raspbian Buster (2019-09-26)
  2. do NOT upgrade / update packages during installation or afterwards
  3. git clone https://github.com/seeed-Studio/pi-hats
  4. cd pi-hats/CAN-HAT
  5. sudo ./install.sh



    During installation you’ll get:

</s>run-parts: executing /etc/kernel/header_postinst.d/dkms 4.19.75-v8+ ./install.sh: line 35: get_kernel_version: command not found !!! Your kernel version is Not found *** coressponding *** kernel headers with apt-get. This may occur if you have ran 'rpi-update'. Choose *** y *** will revert the kernel to version 4.19.75+ then continue. Choose *** N *** will exit without this driver support, by default. Would you like to proceed? (y/N) <e>

  1. Answer with yes: y


  2. Installation will fail with

  1. make
  2. make install
  3. sudo modprobe mcp25xxfd-can
  4. sudo reboot



    should get you up and running:

Hello

I buy new one Raspi 4 and 2-Channe Can Bus shield from seeed.

I cant install shield . it gives error.
I setup last Raspbian version 2020.05.20
I didnt update or upgrade.

enable spi via sudo raspi-config and check
pi@raspberrypi:~/pi-hats/CAN-HAT $ lsmod | grep spi
spidev 20480 0
spi_bcm2835 20480 0
pi@raspberrypi:~/pi-hats/CAN-HAT $
and i checked sudo nano /boot/config.txt
i saw dtparam=spi=on

git clone https://github.com/seeed-Studio/pi-hats
cd pi-hats/CAN-HAT
sudo ./install.sh
and error:

Hi Kahraman

I got the same error as you asked above.
Have you solved it ?

Thanks

#11

Sorry, I have migrated the latest source code to here, but I haven’t had time to update the documentation, we will update it as soon as possible.

#12

till date 17 Oct 2020, the same issues are being experienced here despite installing using the so-called updated DTC overlays release. Very disappointed. Has anyone requested for refund. I simply want my money back and forget about it, about seeed.

#13

https://wiki.seeedstudio.com/2-Channel-CAN-BUS-FD-Shield-for-Raspberry-Pi/ @siowlim_chow We updated and made all the documents public early on.

Hi Shaun, I got the same error when using the 64-bit version of Raspbian. It’s only beta and it seems the kernel headers are not included as source. And I wasn’t able to get the right version.

In the end I installed the 32-bit version of Raspbian. There the kernel headers were included and the drivers could be compiled. And they work fine. I will give it a try again if the 64-bit Raspbian is not beta any longer.

#15

Many thanks, I have got it resolved. However, the 12V power supply was broken, and ever since the Raspbi 4 can not boot. Removing the FDCAN hat and powered through USB-C, the Raspi 4 works.

I have checked the power of FDCAN hat, pin 1 = 0V, pin 2 = 5V. The pins of the 3.3V linear power produce 3.3V, with input 5.0V, ( presumably ).

What could go wrong, please?

#16

Does it not work ? @siowlim_chow
