Is it possible to load firmware into emmc of imx6slevk without using mfg tool?

[sujay1]

I'm using an imx6slevk board with yocto bsp.

The standard procedure for flashing involves copying the compiled images into mfg tools predefined path and using the right mfg tool.

I'd like to avoid using mfg tool.

The board can be connected to a Linux PC via USB and the zimage dtb u-boot and rootfs.tar can be copied to a folder in the board, next time the board boots it should use these images.

Is it possible to do this?

Please note I'm not planning on using SD card for booting.

I found a directory at /run/media/mmcblkp1 that had .dtb and zImage. replacing these files is what I was looking for, but it's not possible to do this for u-boot or rfs

There is no way to program a bare i.MX-based board without using an external tool such as MFGtool.

Please note that there is the UUU - Universal Update Utility tool, that is going to replace the MFGtool:

It is available for both Windows and Linux. Please try it.

Hi Arthur,

Thanks for the reply, just a few questions.

Can the UUU perform according to my specifications?

also has the community released any doc. regarding this tool?

on further digging  I came across a backing storage file is this something I can use for storing boot images?
