Hi,

Previous Android BSPs don’t include exFAT support. I have internally asked to AE team if newer Android BSP already included this support, because it could be added to Linux BSP as explained on the document below:

How to support exFAT in i.MX6DQ Linux release

Hope this will be useful for you.
Best regards!

Hi,

I have confirmed with AE team that we only support FAT and NTFS on Android. The FAT is supported by Linux kernel. NTFS is supported by NXP and it is a user-space file system implemented in Android VOLD.

We don't support extFAT by default. As we all know, there is some license issue about this file system, you can use open source implementation by yourself. For example, extfat-fuse.

Hope this will be useful for you.

Best regards!

Hi,

Just as a FYI, we added it to our Lollipop release using Cyanogen implementation:

Hi Gary,

system/vold/Exfat.h:22:18: fatal error: string: No such file or directory.

Can you give me detailed steps or something reference ?

My OS is android 4.3 for iMX6.
