How to build MCP2515 CANBus drivers for mangOH

64

Yes. I have loaded the latest firmware with legato 16.10.1 and uploaded yocto_wp85.cwe on top of that

65

Ok,send me the steps in a doc with snapshots of each step on your machine. We will troubleshoot and make it work for you. Once done your doc will be released to the community.

66

Meanwhile can you share me yocto_wp85.cwe for temporary fix,as you mentioned earlier.

67

Please use this link for Legato 16.10 CAN yocto_wp85.cwe
This is only temporary and meant to allow you to get going

I have got the same logs after using the above .cwe file.

This is how i’m using my board,what might be the problem.

69

what do you see when you do
ifconfig -a

70

I can’t see anything related to can
All I see is rmnet0-rmnet7 eth0 usb0 wlan0

71

@kiran can you measure voltage at Pin 16 and 17 of U200 (MCP2515). If mux command working good then you must get ~5v

Thanks

72

I have measured and it was showing 0V on both the pins. To get mux working i followed steps as mentioned in below link

Hi all, i’m following the link guide:
https://github.com/mangOH/mangOH/wiki/How-to-build-MCP2515-CAN-driver-for-mangOH-Green-slot-1,-9x15-based-systems.

After the various problems in this guide I have reached this point and I cannot continue:

how do i continue? I need to use menuconfig

74

what module are you using?

75

Hi jyijyi i use WP7607 on mangoh green

76

I remember in WP76 FW R13, in case I need to see the menuconfig, I need to do the following:

# cd yocto
# make dev
build_bin# bitbake linux-quic -c menuconfig

you failed to “make dev”.

you need to do the following first:

sudo apt-get remove ccache
sudo dpkg-reconfigure dash
Answer "No" to the question.

So i retry use the command with bitmake

are you using WP76 FW R13?

how about doing the following?
cd yocto
export LEGATO_BUILD=0
make image_bin
