How to build MCP2515 CANBus drivers for mangOH

didn’t you can download the source here:

yes, but when I download the code:

You can choose “download as zip”

I just found that you can directly download the legato source from,-d-,1-components/#sthash.coj8UBB7.dpbs

Thank you so much, I understand how to take the file.
I have also another problem: in the folder yocto/build_bin/tmp/deploy/images/swi-mdm9x28-wp I find only the file yocto_wp76xx.4k.cwe and not the file yocto_wp76xx_canutils.4k.cwe mentioned in your guide. Where can I find it?

i rename it by myself as i have added the CAN utility.

ok, clear, I understand :pray:

@jyijyi can you see my screen and tell me what to do?

how do you build for the mangoh layer for mangoh green board?

BTW, I only tried in mangoh red board before, you might try in mangoh red board to make sure the CAN board is working fine

i downloaded from link mangOH_2-7-2019_WP75_R16_OK

I modified the file green.sedef uncomment the last line.

I used these commands:

cd Download/mangOH_2-7-2019_WP75_R16_OK/mangOH_2-7-2019/
make clean
make green_wp76xx

After waiting the terminal line :

[1154/1154] Packaging system

in the same folder:

cd build/update_files/green_wp76xx/
update green.wp76xx.update

do you have mangoh red to test?

I only have mangoh green and this is my first time using it. I’m having a lot of trouble getting it to work.

Do you know if there is an updated guide for beginners for green mango, where the connection between leaf, mangOH, yocto etc is explained?

Anyone who knows how to go about fixing the CAN0 problem?

Today the same pass doesnt work

I really don’t understand why it’s so hard to make it work

did you do this?

yes, but…

you can directly download the legato source from,-d-,1-components/#sthash.coj8UBB7.dpbs

I did it, but … :confounded:

Not sure why missing file, You can file the makefile here

I don’t understand why any make is done :pensive: :woozy_face:
