@KV1 nice work! Looks like it made it to U-Boot before it died. Instead of building your own, have you tried to see if it boots using a release image built with a github runner here: https://github.com/bschnei/ebu-bootloader/releases/tag/2026.02.24. Even if you want to eventually build it yourself, you could just test to see if the image built at github works. If it does, and you know the source code is the same (it looks like you are building an -rc of U-Boot) then you can narrow it down to the compiler tools you are using. Just to confirm: this is for an EspressoBIN Ultra right? Not the V7/V5 or some other variant?

At the begginging of the page https://docs.armbian.com/Mirrors/#introduction it is written how the system works. What we don't provide on that list is current status of which are live in in sync. However you can check this at any moment: curl http://apt.armbian.com/mirrors | jq

Hi, Is it appropriate to raise this at https://github.com/armbian/build/issues, since the Headphone Jack audio is available on older version of the kernels and not available in the latest kernels? Thanks for your guidance.

Thanks @bschnei. I tried for a while to figure out what to do, but couldn't really understand.. not sure if i should be trying to set it to thumb or arm mode at that point, even. I did fallback to earlier binutils, and the build went fine. However, trying to boot from the flash-image.bin with mox-imager results in incomplete load and reset back to mmc/spinor ... any ideas? -- /mox-imager/mox-imager -D /dev/ttyUSB0 -t -E /srv/development/espressobin-ultra/2026-03-bschnei/built-on-old-bb/flash-image-20260401-bb.bin TIM version 3.6.00, issue date 2026-04-01, non-trusted, 3 images, 0 keys, boot flash sign SPI NOR Reserved area packages: CRV2 (size 20) CIDP (size 32) Consumer TBRI, packages: GPP1 GPP2 DDR3 GPP1 (size 852) Ignore timeouts in instructions: 0 GPP2 (size 456) Ignore timeouts in instructions: 0 DDR3 (size 2024) Initialize DDR memory: 1 Term (size 8) Found TIMH, hash sha-256, encryption none, size 3780, load 0x20006000, flash 0x00000000 Found WTMI, hash sha-256, encryption none, size 24336, load 0x1fff0000, flash 0x00004000 Found OBMI, hash sha-256, encryption none, size 1140712, load 0x64100000, flash 0x00015000 Going to send images to the device Sending escape sequence, please power up the device Received sync reply Sending escape sequence with delay Detected BootROM command prompt Sending wtp sequence Received ack reply Sending clearbuf sequence Initialized UART download mode GetVersion response: version 3.4.01, date 2016-05-15, CPU ARMA Sending image type TIMH 100% sent in 00:00 TIM-1.0 mv_ddr-devel-g7bcb9dc DDR4 16b 1GB 1CS Sending image type WTMI 100% sent in 00:02 Sending image type OBMI 100% sent in 01:40 [Type Ctrl-\ + c to quit] WTMI-devel-18.12.1-a3e1c67 WTMI: system early-init SVC REV: 5, CPU VDD voltage: 1.213V Setting clocks: CPU 1200 MHz, DDR 750 MHz CZ.NIC's Armada 3720 Secure Firmware v2024.04.15-6-gd6d9646 (Apr 1 2026 16:32:36) Running on ESPRESSObin Ultra NOTICE: Booting Trusted Firmware NOTICE: BL1: v2.14.0(release):sandbox/v2.14-774-g8dae0862c NOTICE: BL1: Built : 16:32:41, Apr 1 2026 NOTICE: BL1: Booting BL2 NOTICE: BL2: v2.14.0(release):sandbox/v2.14-774-g8dae0862c NOTICE: BL2: Built : 16:32:51, Apr 1 2026 NOTICE: BL1: Booting BL31 NOTICE: BL31: v2.14.0(release):sandbox/v2.14-774-g8dae0862c NOTICE: BL31: Built : 16:32:56, Apr 1 2026 U-Boot 2026.04-rc5-00019-gc704af3c8b0f (Apr 01 2026 - 17:08:14 -0400) DRAM: 1 GiB "Synchronous Abort" handler, esr 0x96000044, far 0xd5380000aa1e03fd elr: 0000000000036a08 lr : 0000000000036a64 (reloc) elr: 000000003ff4aa08 lr : 000000003ff4aa64 x0 : 0000000000000098 x1 : d5380000aa1e03fd x2 : 0000000000000000 x3 : 000000003fb07b00 x4 : 0000000000000000 x5 : 0000000000000000 x6 : 0000000000000000 x7 : 000000003fb07b20 x8 : 000000003faff64c x9 : 000000003fb00034 x10: 0000000000000000 x11: 0000000000000600 x12: 000000003faff70c x13: 000000003faff9b0 x14: 000000003faff9b0 x15: 0000000000000000 x16: 0000000000000000 x17: 0000000000000000 x18: 000000003fb03e10 x19: 0000000000000000 x20: 000000003fb07780 x21: 000000003fb077a0 x22: 0000000000000000 x23: 0000000000000000 x24: 0000000000000000 x25: 0000000000000000 x26: 0000000000000000 x27: 0000000000000000 x28: 0000000000000000 x29: 000000003faff7a0 Code: f9405261 f9005274 f81e02a0 f9000681 (f9000034) Resetting CPU ... resetting ...

@alexc Thanks for all your hard work! I’ve put together an Armbian build using your kernel—you can check it out here: https://github.com/NickAlilovic/build/tree/Radxa-mainline-WIP
