I want to rebuild the Linux distribution for my wp76, add the driver of uvc vamera to it, I downloaded the wp76 Linux source code SWI9X07Y_02.28.03.03 Source and extract it, then run make dev in its root directory into the bitbake environment, then Execute bitbake -c menuconfig linux-quic configure uvc and related v4l2 option to M, then save and exit to the root directory make image_bin to get yocto_wp76xx.4k.cwe, then use developer studio to download it to the board.
then he can not pass usb Established a connection with the computer and lost tty_USB0 under /dev, so we tried to use the serial port to establish a connection with the board, although we can log in to the board with the serial port, and we successfully loaded the .ko file of uvc in the shell command line, but after booting up The error message will be returned continuously as follows:
Restart_swi_apps:aplay does not exist
Restart_swi_apps:arec does not exist
Restart_swi_apps:swiapp killed,restart it
Restart_swi_apps:hostapp does not exist
Can someone help me with this problem?
