Hello @Manuel_Salas

Flashed uboot ums enabled software and board is booting, stop at uboot

Once command is executed successfully, eMMC partition 1 and 2 will get mounted to the ubuntu PC

In Ubuntu PC working as expected.

In windows is possible to flash through ums and can we see mounted partition in windows PC?

Hello @Tanu_1827

Yes, I tested by my side and tehre is not problem, the operating system (Windows or Linux) will detect the board as USB Mass Storage.

hello @Manuel_Salas

Yes its detected as a USB. but in our case the partition is in ext4 filesystem which is not compatible on windows. its asking for a format the disk.

Hello @Tanushree

Of course Windows does not support EXT4 natively, you can install a driver for Windows called Ext2Fsd that will read and write EXT4 or a tool called Ext2Read.

I hope this can helps.

Best regards.

UMS utility on Windows is blocked by a read-only mounted partition, when we use Ext2Fsd tool
