UMS update through Windows

[EricBilodeau]

Hello,

Refreshing the following below post :

https://community.nxp.com/t5/i-MX-Processors/Uboot-UMS-flashing/td-p/1851508

Using iMX8DXL processor with partitions mounted in a ext4 format, and while sending ums 1 mmc 0 on boot, the device can be properly mounted on any host PC. The partition can be edited on a Ubuntu based PC, but is apparently mounted as read-only on a Windows 10 PC.

I have tried many EXT4 tools like Ext2Fsd, but the result is the same. I have also tried changing the UUU script when flashing through UUU tool to avoid the following warning regarding 64 bit and metadata_csum : How to use ext4 filesystems in Windows? – atkdinosaurus (wordpress.com)

Hello @EricBilodeau 

As I said in that post, EXT4 is not supported natively in Windows OS. I am not sure the tools that you are using but there is a tool called DiskGenius. 

I tried with this version of the tool:

There you can see the files mounted in the EXT4 partition from windows OS:

Maybe at first that software will identify the EXT4 partition as damaged, but you can make a recovery process (Right click in the EXT4 partition and click on Recover lost files).

Then you will see the files mounted correctly, read and write files in the partition.

So, to do this kind of thing is preferred to use a Linux host machine that supports the EXT4 partition natively.

I hope this information can helps to you.

Best regards.

Salas.
