I made several tests: 1. burn all the possible pairs of SPL / u-boot.img on the existing SDCard --> each time the same story: U-Boot 2018.01-armbian (Jul 07 2019 - 11:26:59 +0200) CPU: Freescale i.MX6Q rev1.2 1200 MHz (running at 792 MHz) CPU: Extended Commercial temperature grade (-20C to 105C) at 33C Reset cause: POR Board: MX6 Cubox-i Watchdog enabled DRAM: 2 GiB U-Boot SPL 2018.01-armbian (Jul 07 2019 - 11:26:59) Trying to boot from MMC1 2. take a new SDCard, dd the SPL.sdhc and u-boot.img.sdhc then use Etcher to burn "Armbian_5.91_Cubox-i_Debian_buster_default_4.14.133" on it, boot with no hard drive connected to the cubox-i: U-Boot 2018.01-armbian (Jul 15 2019 - 21:19:21 +0200) CPU: Freescale i.MX6Q rev1.2 1200 MHz (running at 792 MHz) CPU: Extended Commercial temperature grade (-20C to 105C) at 35C Reset cause: POR Board: MX6 Cubox-i Watchdog enabled DRAM: 2 GiB U-Boot SPL 2018.01-armbian (Jul 15 2019 - 21:19:21) U-Boot SPL 2018.01-armbian (Jul 15 2019 - 21:19:21) U-Boot SPL 2018.01-armbian (Jul 15 2019 - 21:19:21) U-Boot SPL 2018.01-armbian (Jul 15 2019 - 21:19:21) U-Boot SPL 2018.01-armbian (Jul 15 2019 - 21:19:21) U-Boot SPL 2018.01-armbian (Jul 15 2019 - 21:19:21) That is crazy! It seems no more possible to boot that cubox!??!

I will try those images on a clean SD. But, previously, I will try to boot on sata thanks to u-boot.img.sata + SPL.sata... Anyhow, don't you have old images with Debian Stretch instead of Buster? (as I am running Yunohost.org which is not yet compatible with Buster)

Actually, there are several kernels on my SDCard, in the /boot folder. But none is booting. Juste after "Trying to boot from MMC1", it loops back to "U-Boot 2018.01-armbian (Jul 07 2019 - 11:26:59 +0200)" etc.... I don't even understand why it is trying to boot from MMC1, given my armbianEnv.txt & boot.txt What else could I test?

After running: $ sudo dd if=SPL.sdhc of=/dev/sde bs=1K seek=1 status=noxfer $ sudo dd if=u-boot.img.sdhc of=/dev/sde bs=1K seek=69 status=noxfer U-boot seems having well been updated! But it does not boot, it is looping like this: U-Boot 2018.01-armbian (Jul 07 2019 - 11:26:59 +0200) CPU: Freescale i.MX6Q rev1.2 1200 MHz (running at 792 MHz) CPU: Extended Commercial temperature grade (-20C to 105C) at 33C Reset cause: POR Board: MX6 Cubox-i Watchdog enabled DRAM: 2 GiB U-Boot SPL 2018.01-armbian (Jul 07 2019 - 11:26:59) Trying to boot from MMC1 Why MMC1?? armbianEnv.txt: verbosity=7 rootdev=UUID=4a9f4e28-6a2f-4a58-b21a-8b0582b90cd5 console=serial usbstoragequirks= boot.txt: setenv bootargs root=UUID=4a9f4e28-6a2f-4a58-b21a-8b0582b90cd5 rootfstype=ext4 rootwait console=tty1 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 rd.dm=0 rd.luks=0 rd.lvm=0 raid=noautodetect pci=nomsi ahci_imx.hotplug=1 consoleblank=0 vt.global_cursor_default=0 quiet ext2load mmc 0 0x18000000 /boot/dtb/${fdt_file} ext2load mmc 0 0x12000000 /boot/zImage bootz 0x12000000 - 0x18000000 boot.cmd is the default one. Shouldn't I do something with the other files which are in the deb? SPL.emmc SPL.sata SPL.spi-flash u-boot.img.emmc u-boot.img.sata u-boot.img.spi-flash I wanna boot on /dev/sda...

Ok, did it. Now, on the console (via USB-TTL serial console) I have only: U-Boot SPL 2013.10-rc4-ge4bc4c3 (Dec 18 2014 - 14:55:42) Boot Device: SD1 spl: error reading image u-boot.img, err - -1 Load image from RAW...

Should I try updating also the "SPL.sdhc" using: sudo dd if=SPL.sdhc of=/dev/sde bs=1K seek=1 status=noxfer

Thank you a lot for the explanations. I have got a linux computer with a card reader. When inserted, the SDCard is at /dev/sde I have got a final question about the command line: what about its end: "2>&1"? Should I also replace here "&1" by "u-boot.img.sdhc"? What about the "2", should I replace it by "/dev/sde"? That is to say, should I run: dd if=u-boot.img.sdhc of=/dev/sde bs=1K seek=69 status=noxfer > /dev/null 2>u-boot.img.sdhc Or: dd if=u-boot.img.sdhc of=/dev/sde bs=1K seek=69 status=noxfer > /dev/null /dev/sde>boot.img.sdhc

You mean I need to replace the content of the SDCard by the content of u-boot.img.sdhc? Doing so, the boot.src I have just compiled in the SDCard/boot/ folder and the kernels will be overwritten, no?

Thank you! I compiled the boot.src from the boot.cmd I took the v5.90 deb file, extracted it and got three files: control.tar.xz data.tar.xz debian-binary I am sorry but I do not understand how to dd to the SDcard as described: dd if=$1/u-boot.img.sdhc of=$2 bs=1K seek=69 status=noxfer > /dev/null 2>&1 What are $1 and $2? Couldn't I just copy the content of data.tar.xz to the "/usr/lib/" folder of my SDCard?

If I want to update the u-boot manually (as described in https://docs.armbian.com/User-Guide_Advanced-Features/#how-to-unbrick-the-system) , from where should I download the "boot.cmd" dedicated to cubox-i?

I switched from kernel 5.1.16 to kernel 4.14.132: it does not fix the issue I replaced /dev/sda1 by UUID=XXXXXXXXXXXXX in /boot/armbianEnv.txt and in /boot/boot.txt armbianEnv.txt: verbosity=7 rootdev=UUID=4a9f4e28-6a2f-4a58-b21a-8b0582b90cd5 console=serial usbstoragequirks= boot.txt: setenv bootargs root=UUID=4a9f4e28-6a2f-4a58-b21a-8b0582b90cd5 rootfstype=ext4 rootwait console=tty1 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 rd.dm=0 rd.luks=0 rd.lvm=0 raid=noautodetect pci=nomsi ahci_imx.hotplug=1 consolebl ank=0 vt.global_cursor_default=0 quiet ext2load mmc 0 0x18000000 /boot/dtb/${fdt_file} ext2load mmc 0 0x12000000 /boot/zImage bootz 0x12000000 - 0x18000000 All this does not fix the issue: it is still looping and rebooting each time just after "Starting the kernel".

U-Boot SPL 2013.10-rc4-ge4bc4c3 (Dec 18 2014 - 14:55:42) Boot Device: SD1 The strange thing is that even if I set up "verbosity" to 7, no kernel message is displayed...

I am able to boot on the following kernels: 4.14.132 or 5.1.16 (both on the /boot of the SDCard) Currently, the system is set up to boot on 5.1.16. Should I try to switch to 4.14? I can also read the hard drive UUID on my desktop and edit the boot.txt to replace /dev/sda1 with UUID I will also give a look to https://docs.armbian.com/User-Guide_Advanced-Features/#how-to-unbrick-the-system

Hi, After a power shutdown, my Cubox-i 4 Pro does not boot anymore. I am running on it Debian Stretch since years. My system is on a hard drive (/dev/sda1). It seems that the boot process is blocked in a loop, as each time, just after: Starting kernel ... Uncompressing Linux... done, booting the kernel. ...U-boot is restarting as after a fresh reboot.

I suspect a hard drive power issue, as I already had few weeks ago (see the thread below). On the current setup, the hard drive is powered directly thanks to a usb hub, not from the cubox. Please note that the hard drive, plugged on my desktop, is running fine. What could I investigate? Thank you a lot for any support.

I never plug usb sticks on the board.... But I will try replacing /dev/sda1 by UUID=... Thank you Igor for all that Armbian!

Apparently it was an electric power issue (see above). But anyway, I should also implement your proposal (my OS 1st setup is from 2014...). Should I use the UUID in "/boot/armbianEnv.txt" or/and in "/boot/boot.txt"?

OK, finally got it! I have a hard drive plugged to the Cubox-i. This HD is in a box and powered by the Cubox-i via usb. Another usb wire is used for the data. This was working fine like this for years. For any reason, the power delivered by the Cubox-i to the hard drive seems now to be too low. I have used an external power supply for the hard drive and it fixed the issue.
