uBoot on USB? I can petitboot a mini root from usb, but don't know how to load Armbian without a µSD or eMMC stub.

Thanks for the detailed walkthrough. Solved issues with QEMU and editing meson-g12b.conf so far no stack traces dumped with 5.8.7.1_35809.20191129_COEX20191120-7777 88x2bu which is the root goal. normally had them every hr so that's a good sign.

First thanks for the excellent build environment. I'm building BRANCH=current RELEASE=focal BOARD=odroidn2 which makes dpkg-deb: building package 'linux-source-5.10.45-current-meson64' in '/tmp/tmp.8RgxL6czti/linux-source-current-meson64_21.08.0-trunk_all.deb'. but I'm trying to share .ko with the nightly CI image https://armbian.tnahosting.net/dl/odroidn2/archive/Armbian_21.05.4_Odroidn2_focal_current_5.10.43.img.xz because I'm still working out binfmt_misc issues in my hirsute LXC env. update-binfmts: warning: unable to open /proc/sys/fs/binfmt_misc/status for writing: Permission denied update-binfmts: warning: qemu-arm not in database of installed binary formats.

Armbian CI is building v5.10.43 while my local build is making v5.10.45. How can I switch? I've tried all sorts of iterations of KERNELRELEASE= BRANCH= and LIB_TAG= in userpatches/config-example.conf but can't find the right combination to build a v5.10.43 kernel with RELEASE=focal What's the correct build env var and value needed to match Armbian's CI?

Bump. Did you find an overlay for ttyAML1 for your Odroid C2? I need to write one for the N2.

eth0 get link on the N2 with 5.6.18-meson64 (root@builder) but after switching to nightly 5.7.9-meson64 (root@stable) link errors with [ 76.174115] meson8b-dwmac ff3f0000.ethernet eth0: PHY [0.0:00] driver [RTL8211F Gigabit Ethernet] (irq=25) [ 76.278174] meson8b-dwmac ff3f0000.ethernet: Failed to reset the dma [ 76.278892] meson8b-dwmac ff3f0000.ethernet eth0: stmmac_hw_setup: DMA engine initialization failed [ 76.287895] meson8b-dwmac ff3f0000.ethernet eth0: stmmac_open: Hw setup failed I've tracked this to a needed delay in the overlay, a patch is available here: https://forum.khadas.com/t/vim2-ethernet-problem-with-mainline-kernel/5817/7 https://patchwork.kernel.org/patch/10997079/ Thanks for an outstanding build! If there is a bug tracker someplace this should be logged, please point me in that direction.
