Hi i build yocto from source. Make firmware by cwetool. it’s all installed on the board (mangoh yellow )and even works. But wifi and bluetooth dont’ work.
i find some text in readme:
Porting details
We have kept this as a sub-system driver and not integrated with the Legato Kernel
Module Build Architecture such that newer quarterly releases from the
Cypress Developers can be upgraded to. Thus, it is using preBuilt modules.
So i understand that i should insert cypress wifi driver into legato?
hello. We want reduce time of booting. and have some questions:
[ 0.243768] msm_thermal:msm_thermal_dev_probe Failed reading node=/soc/qcom,msm-thermal, key=qcom,online-hotplug-core. err:-517

Why do we have this error, and how can we do thermal management of the device?
[ 1.342268] mdm9607-asoc-snd soc:sound-wm8944: Defering mdm_asoc_machine_probe, q6_state 0
Is it related to sound driver and how can we disable it if we don’t use any sound on the device?
Rootfs mount takes more than 4 seconds. How can we improve it
We have following output while mounting filesystems. Does it point to any issue?
Mounting local filesystems…
[ 10.573338] UBIFS error (pid: 617): cannot open “ubi0:usrfs”, error -19mount: mounting ubi0:usrfs on /usr failed: No such device
5.Do you have any other recommendations regarding optimizing boot sequence times?
