Hmm. I have had issues in the past with some NVMe drives. Such as boot loops and hangs. Try removing the NVMe and see if it stops messin up. Anyway, lets remove 001-Update-SpacemiT-K3-Env.patch Boot tested with custom build "Same patch set applied". https://paste.armbian.com/rukatitize.yaml |

k3picoitx built legacy and current only, so a release target asking for BRANCH=edge produced nothing. Edge tracks AFOliveira/linux riscv/k3-v7.2.6-arch2 - mainline 7.2.6 plus the SpacemiT RISC-V enablement, rather than plain mainline: K3 is not upstream, which is why current points at a fork in the first place, and a stock 7.2 build would carry no K3 support at all. The tree carries arch/riscv/boot/dts/spacemit/k3-pico-itx.dts together with the k3.dtsi and k3-pinctrl.dtsi it includes, and registers k3-pico-itx.dtb in that directory's Makefile under CONFIG_ARCH_SPACEMIT - which is what the board's BOOT_FDT_FILE="spacemit/k3-pico-itx.dtb" expects. linux-spacemit-k3-edge.config comes from ./compile.sh rewrite-kernel-config BOARD=k3picoitx BRANCH=edge seeded from the K1 edge config rather than the K3 current one. Edge is mainline-derived and names the platform CONFIG_ARCH_SPACEMIT, while the 6.18 vendor tree current builds names it CONFIG_SOC_SPACEMIT_K3; seeding from current dropped every SpacemiT symbol at olddefconfig and left a config with no platform support at all. Both ARCH_SPACEMIT and SPACEMIT_K3_CCU exist on 7.2.6-arch2 under the same names, so the config carries over unchanged. CONFIG_EXTRA_FIRMWARE is dropped from that seed. It names esos.elf, which only exists under the K1 blob path and is copied into the kernel worktree by a hook in spacemit.conf that has no K3 counterpart -- Kbuild would have failed looking for firmware/esos.elf. Neither K3 vendor config sets it either; K3's own esos.itb is a u-boot input, not a kernel one. WiFi: EXTRAWIFI is left at its default of yes, so the out-of-tree harness runs here, unlike legacy/current whose vendor trees carry the drivers in-tree. The config also selects the drivers, which the harness alone does not do -- it patches sources in and adds obj-$(CONFIG_...) rules, but unset symbols build nothing.

The onboard Realtek RTL8852BE BT radio (USB 0bda:b85b, on the BT-only usb3_portc controller) never completes HCI init: it enumerates degraded (bcdUSB 1.00, bcdDevice 0.00) and READ_LOCAL_VERSION times out (-110) before btrtl requests firmware, so btusb loops forever resetting the device - spamming the console and wasting power on this PoE-fed board. Hardware-verified: neither the DT reset pulse nor removing reset-gpios stops the loop (the cause is below the reset line - likely a missing BT sleep clock or a USB2-PHY high-speed negotiation issue needing board/PHY work). Disabling the BT-only USB2 port stops the probe entirely; verified on hardware (hci0 gone, zero READ_LOCAL_VERSION failures, board healthy). Matches mainline, which carries no onboard-managed BT node for this board. Signed-off-by: Igor Pecovnik <igor@armbian.com>
inno_dp_probe() only calls component_add(); the struct soc_dp_dev is allocated and platform_set_drvdata() + INIT_DELAYED_WORK() happen later in the component .bind callback (soc_dp_bind). The platform driver's .shutdown and system-sleep PM callbacks fire for the platform device regardless of whether the component ever bound (e.g. a headless K3 Pico-ITX with no DRM master), so platform_get_drvdata() returns NULL and they dereference it - notably cancel_delayed_work_sync(&dp->hpd_work) with dp == NULL. On reboot this faults in systemd-shutdown (PID 1): Unable to handle kernel access ... at virtual address 0x1000 inno_dp_shutdown+0x24 / cancel_delayed_work_sync / platform_shutdown Kernel panic - not syncing: Attempted to kill init! Nothing sets reboot-on-panic, so the board then hangs and only recovers via the physical reset button - i.e. OS reboot/shutdown never actually restarts it. Bail out early when drvdata is NULL in inno_dp_shutdown() and the four system sleep PM callbacks. soc_dp_unbind() is only reached after a successful bind, so it is left untouched.

The kernel compiles and installs fine, then the build dies in packaging with:
basename: extra operand 'Documentation'
Error 1 occurred in SUBSHELL at lib/functions/compilation/kernel-debs.sh:205
The edge tree ships EXTRAVERSION = -arch2, so the kernel installs itself as
vmlinuz-7.2.6-arch2-edge-spacemit-k3. Armbian never sees that suffix:
grab_version() keeps EXTRAVERSION only when it matches ^-rc[0-9]+
(utils-compilation.sh:27), so it computes 7.2.6, and
kernel_version_family becomes 7.2.6-edge-spacemit-k3.
kernel-debs.sh:205 then globs vmlinu*-7.2.6-edge-spacemit-k3 -- the wildcard
sits before the version, so it cannot cover the -arch2 in the middle. Nothing
matches; nullglob drops the pattern entirely, leaving a bare `ls` that lists
the current directory, which kernel_package() has cd'd to the kernel source
root. basename gets COPYING, CREDITS, Documentation, ... and rejects the third.
Clear EXTRAVERSION in the tree. uname then reports 7.2.6-edge-spacemit-k3,
the same shape as every other Armbian kernel, and the upstream revision is
still recorded in the artifact version's S<sha> field.
archive/spacemit-k3-7.2 is the directory edge already defaults to
("KERNELPATCHDIR is unset; using 'archive/spacemit-k3-7.2'"), so no config
change is needed to pick it up.
Verified against the current tip of riscv/k3-v7.2.6-arch2: the patch applies
(git apply --check and patch(1) both clean) and `make kernelversion` then
returns 7.2.6.

Adds an
edgetarget for k3picoitx and fixes two runtime problems on the legacy kernel. All changes hardware-validated on the board.Rebased on
main. The u-boot/OpenSBI bump, the NVMepci enumfix, the SPL trim and the RCPU1 reserved-memory patch have all landed onmainin the meantime (u-boot is now atk3-br-v1.0.8), so those commits are dropped from this branch — the ATF patch would otherwise have been applied twice under two filenames.What remains:
edgebranch for k3picoitx on AFOliveira/linuxriscv/k3-v7.2.6-arch2— mainline 7.2.6 plus the SpacemiT RISC-V enablement. It carriesarch/riscv/boot/dts/spacemit/k3-pico-itx.dtsand registersk3-pico-itx.dtbin that directory's Makefile underCONFIG_ARCH_SPACEMIT, matching the board'sBOOT_FDT_FILE="spacemit/k3-pico-itx.dtb". Config seeded from the K1 edge config, not the K3 current one — edge is mainline-derived and names the platformCONFIG_ARCH_SPACEMIT, while the vendor 6.18 tree usesCONFIG_SOC_SPACEMIT_K3, so seeding fromcurrentdropped every SpacemiT symbol atolddefconfig. Early/experimental: it boots, but most peripherals are not wired up yet.inno_dpDRM driver's shutdown/PM callbacks against NULL drvdata when the DP component never bound (was panicking PID 1 on reboot and hanging the board).Testing
Hardware-tested on a k3picoitx (RISC-V), booting from NVMe over PCIe:
riscv/k3-v7.2.6-arch2has not been built or booted yet, and the config has not been regenerated against that tree.hci0is absent, zeroREAD_LOCAL_VERSIONerrors, systemrunning, no reset-loop log spam.boot_id, no panic, no manual reset) — the unpatched kernel panicked ininno_dp_shutdownand hung PID 1 here.Summary by CodeRabbit
