Hi everyone, I have a mango green with wp7607 and I use the Talon CAN Bus IoT extender for Sierra mangOH IoT. Through leaf I imported into the profile the SDK (swi-wp76_4.0.0 ) for WP76 which provides Relase13 and Legato 19.20.0.
I downloaded the mangOH folder from the following link mangOH_2-7-2019_WP75_R16_OK.tar.gz - Google Drive
I modified the green.sdef file before doing the make by uncommenting the last line that allows me to synchronize the CAN drivers.
I made the green.wp76xx.update file to upload to the board.
I downloaded yocto from the following linkhttps://source.sierrawireless.com/resources/airprime/software/wp76xx/wp76xx-firmware-release-13-components/#sthash.4Ly3Qb5k.dpbs
On the card by executing these commands as reported by the guide :
https://github.com/mangOH/mangOH/wiki/How-to-build-MCP2515-CAN-driver-for-mangOH-Green-slot-1,-9x15-based-systems .

modprobe can

modprobe can-raw
modprobe mcp251x
ip link set can0 type can bitrate 125000 triple-sampling on
ifconfig can0 up
i see
It always says it Cannot find device "can0"
How can I solve this problem?

I don’t see problem to use mangoh green board with WP76 and CAN IOT card.
start_can.sh (1.8 KB) :
green.wp76xx.part2.rar (2.1 MB) green.wp76xx.part1.rar (4 MB)
root@swi-mdm9x28-wp:~# chmod 777 /tmp/start_can.sh

Your .update files don’t work
but i tried your script with my image

your image does not have the can_iot.ko.
BTW, I transfer the .update file to module by scp, and then update by “update /tmp/xxx.update” on module console.
I created the image following your procedure
HBTW, I transfer the .update file to module by scp, and then update by “update /tmp/xxx.update” on module console.
I did it.
So…
How do i add the file can_iot.ko?
Alternatively you can put .upgrade files that work?

the can_iot.ko is inside the green.wp76xx.update file.
didn’t i already put the .update file which is working for me above?
Your .update files don’t work
work for you but not for me

then no idea in case we already using the same FW, maybe hardware issue on your side…
The board is new also the CAN module, they arrived last week and it is the first time that I use them. I think it’s more of a configuration problem or a step that I missed.
Maybe the mangOH folder I used to make the .update file is obsolete…

Then why don’t you use the mangoh source inside my procedure which has proven to be working?
I’m already using that of your procedure, I also linked it to you

Then we are using same thing in software point of view.
Hi, I can’t get CAN driver to work. I used your script start_can.sh but it doesn’t work.
So I found in the web some scripts that have this line:
Do you think that it could be a problem?

are you using my image in mangoh green board?
no, because I can’t unzip your file, it gives me an error

Did you use winrar to unzip
No, I use the command line on Ubuntu VM

Then maybe you try winrar in windows to unzip those 2 files
I think I solved part of the problem, but now, when I update the yocto file on the board, I see it:
Until now I didn’t ever have this problem, because fwupdate is clearly installed…
I don’t understand why is all so difficult for me with this hardware
I solved the problem with the can_iot.ko file, I had to enable the SPI through the menuconfig, I put yocto back but the problem is the same
