So, How can I copy meson-sm1-sei610-ethfix.dtb from SD Card to same folder on eMMC ? Yes while running from sd card you should be able to do: $ mount | grep mmc /dev/mmcblk1p2 on / type ext4 (rw,noatime,errors=remount-ro,data=writeback) /dev/mmcblk1p1 on /boot type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro) /dev/mmcblk1p2 on /var/log.hdd type ext4 (rw,noatime,errors=remount-ro,data=writeback) (If your device is standard you should see that your sc card is device /dev/mmcblk1 with two mounted partitions p1 = /boot and p2 = /) $ ls /dev/mmcblk* /dev/mmcblk1 /dev/mmcblk1boot1 /dev/mmcblk1p2 /dev/mmcblk1boot0 /dev/mmcblk1p1 /dev/mmcblk1rpmb /dev/mmcblk2 /dev/mmcblk2boot1 /dev/mmcblk2p2 /dev/mmcblk2boot0 /dev/mmcblk2p1 /dev/mmcblk2rpmb (Again if your device is standard you should see both mmcblk1 and mmcblk2 - with mmcblk2 being your emmc) $ mkdir tmp $ sudo mount /dev/mmcblk2p1 tmp (mount the first partition of mmcblk2 to ./tmp - this will mount the emmc boot directory to tmp) $ cd tmp $ ls tmp (you should see the contents of your emmc boot directory here, now you can edit the uEnv.txt file, copy to this directory any dtb you wish, etc) $ umount /dev/mmcblk2p1 (un-mount the disk when you are done, shutdown, pull the sd card and reboot to emmc)

Now, this is OK ! @balbes150, maybe this is better if I create a specific topic for my issues and if you can move these posts on it ? Edited May 19, 2020 by Armin
Armin Posted May 21, 2020 Author Posted May 21, 2020 (edited) Hello, After I'm using the meson-g12a-x96-max-no-cvbs DTB file with forcing the ethernet speed to 100Mb (sudo ethtool –s [device_name] speed 100 duplex full autoneg on) but after several tests, the ethernet connection was not stable (poor download speed). Therefore, I have tried several DTB file with SD card booting and best results were confirmed with meson-sm1-sei610-ethfix.dtb. To avoid to transfer the SD installation to eMMC, I have choosen to add the DTB file and Edit uEnv.txt directly on the eMMC. PS: @balbes150, you can move the posts here (from comment-101922 to comment-101969). Greetings Edited May 21, 2020 by Armin
