Hi Lee,

Is there any tool that can write images to enable eMMC boot via gui tool without booting and entering commands with SD card?

Currently, there is no tool to enable emmc via gui tool without booting and entering commands with SD card.

However, you can flash to emmc via DFU boot mode.The below link has the reference for the same.

Also please apply this patch from the <UBOOT FOLDER> for dfu boot mode.

An error occurs.
Is there anything else I need to revise?

Thanks.

Hi Gokul Praveen,

Sorry, it was a problem that was caused by my wrong build.

Referring to the link you sent me, I confirmed that the bootloader is written well.

I want to create an integrated image divided up to the rootfs partition that can be booted with emmc, and write this integrated image in one process.
Is there a way?
Is it possible to write an integrated image through dfu-utils?

thanks.

We are sorry to say that currently we do not have support for this feature.
