In a future release and current beta versions of the Linux 5.4 kernel driver support for the Microsoft exFAT file system. However, this driver is based on old Samsung code (branch version number 1.2.9). In its own smartphones, the company already uses a version of the sdFAT driver based on the 2.2.0 branch.
Now information that South Korean developer Park Ju Hyung has introduced a new version of the exFAT driver based on the latest developments of the company. The changes in the code include not only functionality updates, but also the removal of Samsung-specific modifications. This made it possible to make the driver suitable for all Linux kernels, not just Samsung Android firmware.
The code is already available in the PPA for Ubuntu, and for other distributions it can be built from source. Linux kernels are supported from 3.4 up to 5.3-rc on all current platforms. Their list includes x86 (i386), x86_64 (amd64), ARM32 (AArch32) and ARM64 (AArch64). The developer has already suggested adding the driver to the master branch to replace the old version.
It is also noted that the driver is faster than the version from Microsoft. Thus, we can expect the appearance of an updated exFAT driver, although so far there is no exact data on the timing of the transfer of development to the main branch.
Recall that exFAT is a proprietary version of the file system that first appeared in Windows Embedded CE 6.0. The system is designed for flash drives.
