It is any other way to mount the emmc on a USB host.

Hi @saultr !

Thanks for the question!

I just check the latest configuration of the U-Boot for BSP 6 and it has the ums (USB Mass Storage) enabled (line 43):

https://git.toradex.com/cgit/u-boot-toradex.git/tree/configs/apalis-imx8_defconfig?h=toradex_imx_lf_v2022.04#n43

Most probably you will need to try on the latest nightly release of BSP 6 for Apalis iMX8 to use the ums command:

But, please, be aware that the support for Apalis iMX8 on BSP 6 was not released yet:

Hi @henrique.tx, thanks for the quick reply.

I thought iMX8 was supported from version 6.1.0 in the downstream version, according to: https://www.toradex.com/pt-br/news/bsp-layers-reference-images-yocto-project-6-1-0-quarterly.

I have tested nightly version 6.2.0 and it seems that it has been solved.
Thanks,
