jhoney, uboot finds the .cmd file on the hdd, but this file is not written correctly (it seems to be an exact copy of the one on the sd) and then repeats for about ten times the operation and then freezes. If I could write the .cmd file correctly as it happens for the orangePizero+ it would work.

continues my battle with U-boats, and I appeal to anyone who knows anything. Reading on the forum I found this command to control U-boot strings /dev/mtd0 | grep U-Boot and the result I wrote it in the spoiler below. I did not understand exactly what it means surely is an error during the installation of U-boot that I did with these commands : flash_erase /dev/mtd0 0 128 flashcp /usr/lib/linux-u-boot-next-orangepizero_5.90_armhf/u-boot-sunxi-with-spl.bin /dev/mtd0 Last experiment I compared the script nand-sata install on OP0 and OP0+ but I did not notice differences so the lack of recognition of the spi is to be found upstream.

I also have an OP0+ I checked nand-sata-install and the option SPI=> USB instead exists. attached under the screen . Mysteries!

Yes, I restarted. Finds the mtd0 partition root@orangepizero:~# cat /proc/mtd dev: size erasesize name mtd0: 00200000 00001000 "spi0.0"

I tried martin twice as you suggested, but now when I start nand-sata-install I no longer appear the installation options but only the indication /dev/sda1 the type of formatting and then starts writing armbian on HDD. Mysteries!!!

I've tried these

I think not, I copied with administrator privileges (ubuntu) the whole boot directory from sd to disk

here I copied the directory /boot and changed UUID (there was already written the UUID of the hdd)

Hello Martinayotte , Departed from a clean installation, I cleaned up both hdd and µSD and installed armbian on hdd with the appropriate option in armbian-config. Of course if I restart the OP0 with the µSD inserted everything works fine. I gave the commands you wrote above these are the results (without µSD insertd).

Hi, umiddelb, I tried to clean up the nor spi and recharge an old U-boat but I didn't notice any difference. I noticed a strange thing U-boot when it starts and finds the USB disk looks for a file boot.env not finding it continues finding boot.cmd processes it with error and restarts (this probably because boot.cmd is the one written on the sd card. Even if I recompiled and modified it) . The matter becomes more and more complicated ...

SPI -> SATA/USB boot is just what I'm trying to do. You can tell me (if it's not too complicated) how to do it or where to read a recent tutorial. Below is all I could do.

Hello igor, I tried to modify ArmbianEnv.txt adding setenv rootdev "/dev/sda1 "to boot from hdd without SD , recompiled boot.cmd but it does not work yet. I ask you you can boot completely from hdd (if you like) or I have to settle for boot on sd? P.S. I opened a dedicated post for the problem https://forum.armbian.com/topic/11514-opzero-boot-from-external-usb20-drive-hdd-without-any-sd/

Hello, lanefu. if I understand correctly boot.cmd is generated based on armbianEnv.txt ; but how do you make it generate? I ask you this because I'm trying to start armbian from hhd usb without using the SD

I used armbian-config (https://docs.armbian.com/User-Guide_Getting-Started/#how-to-install-to-emmc-nand-sata-usb) option no. 3 I have the impression that without the sd the boot files that are on the HDD are read but that later on they are discarded because they are not appropriate. The problem is how to edit them correctly (I tried to edit the cmd with /dev/sda1 and recompile, but it does not work) Below in the spoiler there is the boot log when I delete the SD

hello guidol, I'd already read your post (and Martinayotte's) and tried your solutions. I can only start with the sd connected, if I take it off it crashes and goes into a loop as you see in the spoiler above.
