Hello,

I want to activate the spidev with modprobe command and than I got the message that
modprobe: module spidev not found in modules.dep
Moreover, when I execute the dmesg command it appears that the system cannot bound correctly with the device tree. hereafter what I got when I execute this command :
root@swi-mdm9x28:/# dmesg | grep spi

Can you please help me with that. Thank you

Any idea about this issue please ?

Are you using the release 8 firmware for WP76?

yes, I am using the last one 18.01.0_607d14ac5f0edd90fada704659a46736.

this is what I got as logread when starting the spiService API :

I think the spidev1.0 is the used one by the WP76 not the spidev0.0. Do you know how to change that ?

Hi @Souhail, I have Mangoh. RED - WP7609 with exactly same problem!!

I built my own image yocto_wp76xx.4k.cwe from Legato-Dist-Source-mdm9x28-SWI9X07Y_02.28.03.05.tar.bz2 (R13.3) without any modification and spidev0.0 is not in /dev/.

after burn image, on target: $ dmesg | grep spi

Same as you!

Looks like a dts issue!

Did you solve this issue?
