Hi Experts,
I am debugging an OEM project with Android 4.2.2_r1.
BSP: Panda5AJ.1.5.1
OS Kernel: Linux® 3.4.48
Android: Android JellyBean 4.2.2_r1
Toolchain: Andriod linux-x86 toolchain arm-eabi-4.6
Reference hardware platforms: TI OMAP5 5432 uEVM ES2.0 (Panda5)
Build Host OS: Ubuntu
I am facing a kernel panic issue of FUSE.
Android mounts a single emulated external storage via a FUSE daemon at EMULATED_STORAGE_SOURCE.
Camera will store pictures into EMULATED_STORAGE_SOURCE.
Normally, it works fine.
However, sometimes, it will suddenly panic with no sign.
I have altered the mount flags in the fstab for EXT4 and "android/system/core/sdcard" for FUSE.
Also, I have checked "android/system/core/sdcard", "linux/fs/fuse", "linux/fs/ext4" and found nothing.
Does anyone else have meet this issue and can share some experience ?
