Updating U-Boot was the solution, kernel is now up to date!!! Thanks everyone for the tips, learned a few new things and the UART cable is really usefull!

@Werner @SteeMan Hah, I legit didn't know about the armbian-install command. I updated the bootloader and I guess I'm more up to date now U-Boot on boot is now U-Boot 2026.04_armbian-2026.04-S88dc-P3cfe-H5025-V315b-Bd0d2-R448a (May 30 2026 - 05:51:20 +0000) odroid-n2/n2-plus Gonna try to update the kernel now

@Werner I only installed Armbian (written image through BalenaEtcher to emmc card) I reflashed Petitboot on SPIFlash a few weeks ago since I broke it while testing but the kernel update was broken months before that. Don't think they affect each other. I boot PetitBoot through the physical switch on the board itself (So SPIFlash) so it should have it own separate U-Boot. @eselarm I think on my board you can physically switch if SPI-flash or eMMC is used. If I set the switch the eMMC it should take the bootloader on the eMMC? https://wiki.odroid.com/odroid-n2/software/boot_sequence It feels more like the boot format changed from 6.12.xx to 6.18.xx? If I look at my installed packages I do have the latest available u-boot btw linux-u-boot-odroidn2-current: Installed: 26.5.1 Candidate: 26.5.1

Finally got an UART device for logs U-Boot 2015.01 (Sep 01 2020 - 18:41:51) DRAM: 3.5 GiB Relocation Offset is: d6eeb000 spi_post_bind(spifc): req_seq = 0 register usb cfg[0][1] = 00000000d7f83da8 MMC: aml_priv->desc_buf = 0x00000000d3edb7c0 aml_priv->desc_buf = 0x00000000d3eddb00 SDIO Port C: 0, SDIO Port B: 1 co-phase 0x3, tx-dly 0, clock 400000 co-phase 0x3, tx-dly 0, clock 400000 co-phase 0x3, tx-dly 0, clock 400000 emmc/sd response timeout, cmd8, status=0x1ff2800 emmc/sd response timeout, cmd55, status=0x1ff2800 co-phase 0x3, tx-dly 0, clock 400000 co-phase 0x1, tx-dly 0, clock 40000000 aml_sd_retry_refix[983]:delay = 0x0,gadjust =0x12000 [mmc_startup] mmc refix success [mmc_init] mmc init success In: serial Out: serial Err: serial vpu: error: vpu: check dts: FDT_ERR_BADMAGIC, load default parameters vpu: driver version: v20190313 vpu: detect chip type: 9 vpu: clk_level default: 7(666667000Hz), max: 7(666667000Hz) vpu: clk_level = 7 vpu: vpu_power_on vpu: set_vpu_clk vpu: set clk: 666667000Hz, readback: 666666667Hz(0x100) vpu: set_vpu_clk finish vpu: vpu_module_init_config vpp: vpp_init vpp: g12a/b osd1 matrix rgb2yuv .............. vpp: g12a/b osd2 matrix rgb2yuv.............. vpp: g12a/b osd3 matrix rgb2yuv.............. cvbs: cpuid:0x29 cvbs_config_hdmipll_g12a cvbs_set_vid2_clk ** File not found boot-logo.bmp.gz ** ** File not found boot-logo.bmp ** movi: not registered partition name, logo movi - Read/write command from/to SD/MMC for ODROID board Usage: movi <read|write> <partition|sector> <offset> <address> [<length>] - <read|write> the command to access the storage - <offset> the offset from the start of given partiton in lba - <address> the memory address to load/store from/to the storage device - [<length>] the size of the block to read/write in bytes - all parameters must be hexa-decimal only [OSD]check dts: FDT_ERR_BADMAGIC, load default fb_addr parameters [OSD]set initrd_high: 0x3d800000 [OSD]fb_addr for logo: 0x3d800000 [OSD]check dts: FDT_ERR_BADMAGIC, load default fb_addr parameters [OSD]fb_addr for logo: 0x3d800000 [OSD]VPP_OFIFO_SIZE:0xfff01fff [CANVAS]canvas init [CANVAS]addr=0x3d800000 width=5760, height=2160 cvbs: outputmode[1080p60hz] is invalid vpp: vpp_matrix_update: 2 set hdmitx VIC = 16 config HPLL = 5940000 frac_rate = 1 HPLL: 0x3b3a04f7 HPLL: 0x1b3a04f7 HPLLv1: 0xdb3a04f7 config HPLL done j = 6 vid_clk_div = 1 hdmitx phy setting done hdmitx: set enc for VIC: 16 enc_vpu_bridge_reset[1319] rx version is 1.4 or below div=10 Net: dwmac.ff3f0000 Hit Enter or space or Ctrl+C key to stop autoboot -- : 0 ## Attempting fetch boot.ini in mmc:0... ** File not found boot.ini ** ## Executing script at 04000000 Wrong image format for "source" command ## Attempting fetch boot.scr in mmc:0... ** File not found boot.scr ** ## Executing script at 04000000 Wrong image format for "source" command ## Attempting fetch /boot/boot.ini in mmc:0... 5578 bytes read in 5 ms (1.1 MiB/s) ## Executing script at 04000000 0 bytes read in 3 ms (0 Bytes/s) Found mainline kernel configuration HDMI cable is NOT connected 178 bytes read in 5 ms (34.2 KiB/s) ** File not found uImage ** 42404352 bytes read in 1187 ms (34.1 MiB/s) ** File not found dtb/amlogic/meson-g12b-odroid-n2-plus.dtb ** 83033 bytes read in 29 ms (2.7 MiB/s) ** File not found uInitrd ** 22881405 bytes read in 642 ms (34 MiB/s) ee_gate_off ...

After this it loops it for all mmc/usb devices and breaks. I need to manually copy old kernel files to /boot to get it to work again (through petitboot) Anything after 6.12.58 seems to break for me. Thoughts?

I don't have a device for that. Which one would you recommend getting? I might try it out later when I get time (not soon so if anyone else is able to post logs?)

@Werner Which logs would be usefull? I have a full image from the broken state. Kern.log is empty (0 bytes) syslog only has log from the last shutdown and ends there dmesg is from last startup before the system broke

Just a warning for everyone, the new kernel update (6.18.xx I think?) absolutely wrecks the system (atleast it does on Ubuntu Noble). It doesn't boot at all anymore I needed to recover an old kernel from an old backup I had and overwrite the current kernel from rescue mode/petitboot. Kernel 6.12.xx seems to work fine(ish) Just a heads up because I don't know enough to pinpoint the exact cause. p.s. for me the kernel means the files in /boot not sure if I used proper terminology

Latest kernel upgrade broke the odroid again, executing the command by @jbergler (with manually changed kernel version) fixed it again.

I upgraded the kernel today via apt-get update/upgrade and it seems kernel for armbian 23.08 is being pushed to users with 23.02 breaking a bunch of stuff. After upgrading the kernel ethernet stops working and requires the user to manually downgrade kernel, uboot (and dtb?). I am currently on "current" kernel (6.1.11-meson64) I'm thinking of downgrading to legacy (5.xx) via armbian-config, does anyone know if this is safe?

Hello everyone, Upgrading from distro isn't supported officially but I tried it anyways and thought I should share my findings. In short, it worked for me. Others have reported issues so maybe we can figure out what causes these issues. My N2+ is fairly vanilla, so I didn't heavily modify it. Running 5.10.x kernel since that is recommended for de N2+ Step 1. Fully upgrade your system on Focal sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade Step 2. Shutdown you N2+ and make an image backup of your emmc using dd or Win32DiskImager in case something goes wrong Step 3. Boot up your N2+ again, disable all 3rd-party applications and PPA and change the release your sources list. sudo sed -i s/deb/#deb/ /etc/apt/sources.list.d/*.list sudo sed -i s/focal/jammy/ /etc/apt/sources.list Step 4. Update sources sudo apt-get update Step 5. This is were the tricky part starts, upgrading packages. Apt will ask to automatically restart services, allow this. Apt will also ask to replace configuration files, personally I kept all my configurations after manually checking them. sudo apt-get upgrade sudo apt-get dist-upgrade Step 6. Reboot the device And if everything works fine Step 7. Re-enable 3rd party applications and PPA and change the release sudo sed -i s/#deb/deb/ /etc/apt/sources.list.d/*.list sudo sed -i s/focal/jammy/ /etc/apt/sources.list.d/*.list sudo apt-get update sudo apt-get dist-upgrade Step 8. Do a last reboot and done, you should be on Jammy. Remember manually upgrading like this is not officially supported by armbian!
