Hello,
I’m tring to building legato and linux for a custom device with WP7702.
I’ve downloaded the legato source and swi-linux source with leaf. I can build legato with (make wp77xx) but I’m not able to customize the swi-linux-src (make menuconfig ???) to add support in kernel for BMI160 (On my board I have no i2c mux … removed couse not used).
Can someone help me with swi-linux build? I have this error right now:

You can now run ‘bitbake ’

core-image-minimal
core-image-sato
meta-toolchain
meta-ide-support
You can also run generated qemu images with a command like ‘runqemu qemux86’

Done… it worked. Now I have enabled support for BMI160 in kernel and saved the config.
How can i build the entire linux? And do it for wp7701… ? Also… in my experience (android kernel), i have DTS to indicate i2c address and presence of accelerometer under i2c bus…
Yes… but i cant use mangoH cause it defines communication with accelerometer through i2c multiplexer, and i dont have it on my board.
So the master plan is this:
1)Build legato (DONE…)
2)Configure kernel on linux source with BMI support (not enabled by default but i enabled right now…DONE)
3)Make kernel and linux for WP7702 (dont know how to do it)
4)Make legato for WP7702 (dont know how to do it)
5) Merge legato.cwe linux.cwe and modemdrivers to produce a complete system.
(lsh:wp77) gianmaria@leg:~/myWorkspace/swi-linux-src$ make dev
Makefile:8: *** “Detected Makefile being re-invoked from within bitbake environment!”. Arresto.
Useless command… found on help.
Anyway seems I’ve compiled everything… now I’ve:
LEGATO HERE:
/home/gianmaria/myWorkspace/legato-src/legato/build/wp77xx/legato.cwe
LINUX HERE
/home/gianmaria/myWorkspace/swi-linux-src/build_bin/tmp/deploy/images/swi-mdm9x28-wp/yocto_wp77xx.4k.cwe
It worked… file by file… it worked.
Anyway i still didt see my BMI160 even if it’s enabled in kernel drivers cause i need to know witch DTS to edit to declare it… there are a lot of it and i dont know wich is the right one to define the accel i2c address… something like this:
