4.2.4 Flash eMMC from USB
Flash eMMC from USB in Linux
These steps will show how to ash the eMMC on Linux with a USB stick. You only need a complete image
saved on the USB stick and a bootable WIC image. (e.g. phytec-qt6demo-image-phyboard-segin-imx93-
2.wic). Set the bootmode switch (S3) to SD Card.
• Insert and mount the USB stick:

[ 60.467286] scsi host0: usb-storage 1-1.1:1.0

target:~$ mount /dev/sda1 /mnt
• Now show your saved image les on the USB Stick:
target:~$ cd /mnt
target:~$ ls
phytec-qt6demo-image-phyboard-segin-imx93-2.wic
• Show list of available MMC devices:
target:~$ ls /dev | grep mmc
mmcblk1
mmcblk1p1
mmcblk1p2
mmcblk0
mmcblk0boot0
mmcblk0boot1
mmcblk0p1
mmcblk0p2
mmcblk0rpmb
• The eMMC device can be recognized by the fact that it contains two boot partitions: (mmcblk0boot0;
mmcblk0boot1)
• Write the image to the phyCORE-i.MX 93 eMMC (/dev/mmcblk0 without partition):
target:~$ dd if=phytec-qt6demo-image-phyboard-segin-imx93-2.wic of=/dev/mmcblk0 bs=1M␣
,→conv=fsync status=progress
• After a complete write, your board can boot from eMMC.
Tip
Before this will work, you need to congure the bootmode switch (S3) to eMMC.
