[manoloruiz]

Hi,

I want to load everything from a MicroSD. Is it possible? I tried to load the uboot from MicroSD. But I would like to know if I can load everything together from the flash.

thanks.

Yes. You can load everything from a MicroSD.

You can learn how to build and install the NXP Linux OS BSP by i.MX_Linux_User's_Guide.pdf (in the L4.1.15_1.1.0_LINUX_DOCS)

All the best

Once the system booted into u-Boot, the rest is done by u-Boot commands.  Depending on how your SD card is partitioned and formatted, you can read Linux and DTB images into memory with mmc read, ext2load or fatload commands. Linux can use

an SD/MMC card directly as a root filesystem device.  Pre-u-Boot SD card preparation steps are described here:

For required u-Boot CLI commands refer to your board deployment guide:
