MT7697 Built In WiFi Problem

Legato Application Framework
1

Hi, I am working with the WP77XX with Firmware release 11, Legato FW 18.09, and I am getting error when I try ifup wlan1

root@swi-mdm9x28:~# ifup wlan1
Setup MT7697 UART
Device: WP77
Enable power control
Initialized Linux WiFi modules
insmod: can’t insert ‘/legato/systems/current/modules/mt7697wifi_core.ko’: No such file or directory

I have followed the wiki (mangOH Red mt7697 WiFi · mangOH/mangOH Wiki · GitHub) working in the VM. I also followed another thread (Using WiFi on mangOH Red + wp76xx running Legato 19.02 AF - #3 by luisvi70 - mangOH Red - mangOH forum) assuming that building the WiFi module would add the required kernel modules. When trying to build mksys -t wp77xx wifi.sdef. I get the following error:

Hi @BroderickJack

Try with Legato 19.01. It worked for me. Note that I built a Legato system with just the kernel modules, patches and scripts from mangOH. I’ve attached my sdef fore reference. red_MT_wifi.sdef (2.6 KB) . You can softlink this to default.sdef

a:leaf_workspace$ leaf setup WP77_R11 -p swi-wp77_2.0.0
a:leaf_workspace$ leaf shell

(lsh:WP77_R11) a:legato-19.01.0$ instsys build/wp77xx/system.wp77xx.update 192.168.2.2

Then I updated /etc/network/interfaces and added /etc/init.d/mtwifi,

My Wifi AP script mangOH-red-MT-wifi-AP.sh (7.4 KB) . You can change the APN and try it out.

Please update on how it goes for you.

Hi @Alegato thanks for getting back to me!

I followed your steps but when I get to make wp77xx I get a bunch of format-truncations errors:

HI @BroderickJack, I used a Ubuntu 16.04 64 bit with all latest updates. Also, please ensure that the cross compiler is setup correctly (leaf shell and then env to check the environment variables). My build machine details are below:
