Hi all,
Greetings !!!
I am using USB camera with AM335x for Android KitKat 4.4.
Kernel Version - 3.2
I have done all compilation setup by using the below link. SDcard image is working perfectly.
https://github.com/csimmonds/bbb-android-device-files/tree/kk4.4-sdcard
For USB Camera i have done all the changes as per the below wiki link,
http://processors.wiki.ti.com/index.php/TI-Android-JB-4.2.2-DevKit-4.1.1_PortingGuide#USB_camera
I cross compiled the kernel and flashed the new kernel image into MMC. i am getting the video0 in /dev.
but when i open the camera application, it is closing immediately. not throwing any error on display.
here I am attaching the Logcat log for reference.
Log:
