Mainline U-Boot and Kernel restarts during boot

qxhz · April 14, 2026, 5:17pm

First of all, I’ve managed to install Gentoo on Radxa ZERO 3E. It was a rather simple install: separate boot and rootfs partitions, both with ext4, no initramfs, mainline kernel and u-boot, it was compiled using systemd-nspawn and qemu-aarch64 on another machine. While installing I was making notes about what, why and how, which gave me few pages of description how to build a system for this SBC, which should be more than less correct, unless something changed in one year.

Now, I’m trying to install Gentoo on a Radxa ROCK 5 ITX using my notes from ZERO, with some changes:

rootfs is on ZRAID1 ZFS on SATA SSDs,
initramfs (darcut),
GRUB,
build on the SBC, using Armbian.

Kernel is gentoo-sources-6.19.12 with defconfig, defconfig worked with ZERO, so I think it should allow to at least to boot. Grub-2.14 was successfully installed, but grub-mkconfig doesn’t work. Dracut-108, ZFS-2.4.1.

Building U-Boot:

cd /usr/src
git clone GitHub - u-boot/u-boot: "Das U-Boot" Source Tree · GitHub -b v2026.04 --depth=1
git clone GitHub - rockchip-linux/rkbin: Firmware and Tool Binarys · GitHub --depth=1
git clone GitHub - ARM-software/arm-trusted-firmware: Read-only mirror of Trusted Firmware-A · GitHub --depth=1
make -j8 -C arm-trusted-firmware CROSS_COMPILE=aarch64-none-elf- PLAT=rk3588
make -j8 -C u-boot rock-5-itx-rk3588_defconfig
make -j8 -C u-boot ROCKCHIP_TPL=/usr/src/rkbin/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2400MHz_v1.19.bin BL31=/usr/src/arm-trusted-firmware/build/rk3588/release/bl31/bl31.elf

Partition table on a SD card:

Model: Generic STORAGE DEVICE (scsi)
Disk /dev/sda: 121241600s
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 64s 7167s 7104s idbloader.img
2 16384s 24575s 8192s u-boot.itb
3 32768s 2032768s 2000001s fat32 efi boot, esp
4 2033664s 3905535s 1871872s ext4 boot

I plug SD card in and start the machine, then I run Grub with:

load mmc 1:3 $kernel_addr_r /EFI/gentoo/grubaa64.efi ; load mmc 1:3 $fdt_addr_r u-boot.dtb ; bootefi $kernel_addr_r $fdt_addr_r

Device tree is from the u-boot. Then I load and run the kernel:

linux /kernel-6.19.12-gentoo
initrd /initramfs-6.19.12-gentoo.img
devicetree /rk3588-rock-5-itx-6.19.12.dtb
boot

Device tree is from the kernel. Then it boots for a few seconds and whole SBC restarts:

I’ve tried specifying root= and rd.break hoping for Dracut rescue shell or at least kernel panic, but it is always restarts. Booting kernel straight from U-boot using bootefi gives same result. When I tried to boot kernel configured with make allyesconfig I got EFI stub: ERROR: Failed to locate PCI I/O handles. and board hangs instead of restarts.

You mention mainline config and ZFS. That contradicts. ZFS is not Linux. Also nothing is shown w.r.t. ZFS in the kernel log. I think this is a typical ZFS-Linux integrattion issue, is going on for a decade or so. You need to dig deeper if you want this.

I have used ZFS long time ago full custom kernel and patching, was SuSE Linux. Also just native FreeBSD, that is a lot easier as it works out-of-the-box. But is 10 years ago, I do not use RAID anymore, certainly not on a rootfs. All Btrfs now, works fine on RK3588, even standard Debian sid 16k pages kernel (6.19.11+deb14-arm64-16k).

.

qxhz · April 15, 2026, 7:55am

ZFS was build as a module into a initramfs. I also tried to boot without the initramfs and initramfs but without ZFS and same result.

I mentioned gentoo-sources kernel, this is kernel with few patches, but I also tried kernels from kernel.org, and again same result.

radrocks · April 15, 2026, 9:24am

Only new idea/comments is that the ITX has extra SATA chip and there was a very nasty issue with power or signalling w.r.t. that. Is a year ago or so, should be fixed in recent kernel sources, see Armbian forum I think.

I use only 1 SATA and is the on-SoC mutli-PHY 1-lane that is normally for WiFi E-key cards. And EDK2 UEFI v1.1 firmware/bootloader where I put that as setting (persistent in SPI-flash). Is for ROCK5B by the way, using standard 4k pages (6.19.11+deb14-arm64).

Also means there is no latest U-Boot for me and no extra .dtb loaded. It just relies on the DT provided by the v1.1 firmware, which is about 1 year old now.

qxhz · April 16, 2026, 4:31am

I was thinking about EDK2, but since Grub works I thought this might not be it. I’m thinking about trying it, but AFAIK Armbian doesn’t support UEFI. Wouldn’t installing EDK2 prevent me from booting Armbian from SD card?

radrocks · April 16, 2026, 6:49am

If you have more than 1 bootloader for the system, then which one is used at power on and loading the OS? That is the question and I am not sure if it is all the same for the hundreds of SBC’s. I have 3 RK35xx based boards and all different. Look in the docs. Usually SD-card has priority I think.

Or make sure you have just 1 bootloader, then you are sure which one.

So in the phase you are now and knowing that this an ‘Intel PC’ like board, I would boot from SD-card, then write teh EDK2 UEFIv1.1 into SPI-flash, power-off, remove SD-card, power-on and hit ESC button. I works via HDMI+keyboard and also when only serial console cable is attached. Then in the menu select boot from file and browse to grubaa64.efi or bootaa64.efi. It assumed you have a standard EFI bootable setup on some storage, might be USB ISO OS installer.

Also learn yourself how to wipe just the U-Boot from an SD-card and also wipe SPI-flash. You now have multiple partitions for U-Boot, that is complex w.r.t. so why doe you doe this. U-Boot sits on a fixed sector offset between primary partition table and first partition. Use dd to write of wipe. Is also in the docs here on Radxa site for various boards. If you want Gentoo, ZFS, fist make sire you also understand the bootloader basics. Then the rest is all trivial.

FWIW, mainline is working for me as expected:

I’m running firmware with U-Boot as payload on all my various devices. This way I’m able to run the same OS of my choice on all my aarch64 devices.
I prefer SPI flash as firmware location, since that way I have just to flip my USB NVME enclosure around to use a different device. If no SPI flash is available, I use a microSD card as storage location because this is the most convenient way to manipulate the firmware setup.
The ROCK-5-ITX has unfortunately no way to enforce a different boot device (e.g. microSD card).
The only way to use firmware without first deleting the existing firmware on higher-priority boot devices is the MASK ROM mode and booting from RAM.
Unfortunately, this complicates a previous test of another firmware that might be used.

I flashed EDK2 into SPI and now it is working, I can use Grub over serial and it boots without an issue. I was afraid of bricking the system and unable to fix it without desoldering chips, but rkdeveloptools looks like something bullet proof. I can’t boot ROOBI any more, but I can boot Armbian when I swap SD card, which is nice, but I’m don’t know why.

According to 10th page of schematic, boot order is FSPI_M2-FSPI_M1-FSPI_M0-EMMC-SD Card-USB, which I believe means:

SPI flash (now with EDK2),
EMMC (with ROOBI),
SD Card (Gentoo/Armbian in my case),
USB (rkdeveloptools).

When I plug in SD card with Gentoo, it runs EDK2 from SPI and it runs Grub and then Gentoo, that makes sense to me. But when I plug in SD card with Armbian it skips EDK2 and boots Armbian, which I don’t understand.

Also, I can boot Gentoo without loading devicetree in Grub, is a devicetree embedded into EDK2?

That is the priority list of the MASK ROM code. Wherever a firmware signature is first found in this sequence, this boot device is selected. The firmware in the boot device is transferred into RAM and the execution control is handed over to it. How the boot process continues is entirely dependent on what the respective firmware implements.
As can be seen from the schematic, only the MASK ROM mode can be selected as an alternative. That is, if a boot device further back in the list is to be used, it must be ensured that there is no valid firmware in any other boot device earlier in the list.
So one cannot switch reversibly between alternative firmware on different boot devices. Hopefully one has a suitable backup ready when testing new firmware and it turns out to be unusable.

yes, if you have configured ‘DeviceTree‘ in the setup. See EDK2 docs/readme on github. Also ACPI is possible or a mix.
