@fensoft I am using your current image 3.0.0_r2 in H96 Max M1 with USB Hub + USB to Ethernet adapter successfully. Its really energy efficient solution which can run 24 x 7 without costing much. However I am trying to set this up on a dq08 box with 4 GB/64 GB Model. I am able to install dq08_ha_supervised_3.0.0_r2.zip without any issue. However due to recent support changes from the application, I am unable to continue further with the setup. I tried to install docker version to set this up but getting error "invalid argument: in-kernel BTF is malformed (1 line(s) omitted)". Not seeing much on this error in the interwebs but there are suggestions that this could be due to old kernels/. Is there a way we can update this kernel and OS to Armbian Trixie or will it brick the dq08? Have you got a chance to look at the updated installer image?

Okay so then we have some issues here This is clearly wrong since these packages come from upstream Debian and cannot/will not work with Armbian kernels. This shall be reported here: https://github.com/armbian/configng/ Then you were lucky some working headers were present https://docs.armbian.com/Developer-Guide_Build-Preparation/ Or in very short: git clone the repo ./compile.sh BOARD=rockpi-4bplus BRANCH=current kernel Check output/debs for your packages Install via dpkg -i on the target board

Thanks, @Werner! I believe I can do it once I find clear instructions. There's still a lot I don't understand—where all needed things are. I'd appreciate it if you could just provide a link that could point me in the right direction. Meanwhile, yesterday I somehow managed to install the headers using apt-get install linux-headers-current-rockchip64 . At least, for now, this allowed me to build the packages that needed the headers. It seems like this might be a bit of a dirty trick (no?). So, I'd still like to do it right.

I've been working on getting Armbian running on an H96 Max RK3528 TV-box (board marking RK3528_DDR3_8X4_V12) with 4GB DDR3 and 64GB eMMC running stock Android 13. I'm building on Ilya Kurdyukov's work (github.com/ilyakurdyukov/rk3528-tvbox) and have made significant progress, but I've hit a wall and need guidance. WHAT WORKS 1. Flashed custom U-Boot (2017.09 Rockchip with Ilya's patches + my custom patches for USB host activation and USB-first boot) via rkdeveloptool. 2. Added patches to enable USB host in U-Boot DTS: &u2phy_host, &usb_host0_ehci, &usb_host0_ohci all set to status = "okay"; &usbdrd_dwc3 set to dr_mode = "host", status = "okay". 3. Modified distro_bootcmd so boot_targets = "usb0 mmc1 mtd2 mtd1 mtd0 pxe dhcp" — network boot is attempted before Android fallback. 4. Built Armbian image with BOARD=rk3528-tvbox, BRANCH=legacy, RELEASE=jammy, xfce desktop. 5. TF-slot does not work (box hangs when microSD inserted in TF slot, likely BootROM SD-boot disabled via OTP as @jock mentioned in other RK3528 threads). 6. USB card reader with microSD works in U-Boot — I see "U-Boot.armv8" DHCP client on my Mikrotik router at IP 192.168.55.114. 7. Set up PXE boot infrastructure: dnsmasq TFTP server on 192.168.55.228, NFS rootfs export on same server (/srv/nfs/armbian-rootfs), Mikrotik DHCP configured with next-server and boot-filename options. 8. U-Boot successfully downloads via TFTP: pxelinux.cfg/01-c6-33-00-3f-cb-3c (PXE config by MAC), Image (kernel, 34 MB), and dtb/rockchip/rk3528-android.dtb (extracted from stock Android boot.img, compatible: "rockchip,rk3528-evb2-ddr3-v10", "rockchip,rk3528"). WHAT DOES NOT WORK After TFTP downloads complete, the kernel appears to never start: — HDMI shows only grey screen (U-Boot logo from Ilya's gray_square_logo patch). — No kernel DHCP request on network (would indicate IP_PNP starting). — No NFS activity (nfsstat -s shows calls = 0). — No ARP responses from the box — only Mikrotik ARP requests to .114 appear in tcpdump. — Eventually Android fallback loads (boot_android runs after distro_bootcmd fails). EVIDENCE — NETWORK TRACES dnsmasq log confirms successful TFTP downloads: Apr 24 01:33:38 dnsmasq-tftp: sent /srv/tftp/pxelinux.cfg/01-c6-33-00-3f-cb-3c to 192.168.55.114 Apr 24 01:33:45 dnsmasq-tftp: sent /srv/tftp/Image to 192.168.55.114 Apr 24 01:33:45 dnsmasq-tftp: sent /srv/tftp/dtb/rockchip/rk3528-android.dtb to 192.168.55.114 Then complete silence from the box. tcpdump — U-Boot DHCP + TFTP sequence (this part works): 00:45:24.375253 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from c6:33:00:3f:cb:3c, length 300 DHCP-Message: Discover, ARCH=22, Vendor-Class: "U-Boot.armv8" 00:45:24.878890 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from c6:33:00:3f:cb:3c DHCP-Message: Request, Server-ID: 192.168.55.1, Requested-IP: 192.168.55.114, Vendor-Class: "U-Boot.armv8" 00:45:24.942243 IP 192.168.55.114.1583 > 192.168.55.228.69: TFTP, RRQ "pxelinux.cfg/01-c6-33-00-3f-cb-3c" octet timeout 5 blksize 1468 00:45:25.005127 IP 192.168.55.114.1646 > 192.168.55.228.69: TFTP, RRQ "uInitrd" octet timeout 5 blksize 1468 00:45:28.349357 IP 192.168.55.114.1918 > 192.168.55.228.69: TFTP, RRQ "Image" octet timeout 5 blksize 1468 00:45:35.412847 IP 192.168.55.114.2837 > 192.168.55.228.69: TFTP, RRQ "dtb/rockchip/rk3528-evb2-ddr3-v10.dtb" octet timeout 5 blksize 1468 All files transfer successfully (observed via TFTP ACK packets). tcpdump — after booti, everything goes silent. The only traffic about the box is Mikrotik's ARP probes: 00:55:19.283404 ARP, Request who-has 192.168.55.114 tell 192.168.55.1 00:55:20.296683 ARP, Request who-has 192.168.55.114 tell 192.168.55.1 00:55:21.346711 ARP, Request who-has 192.168.55.114 tell 192.168.55.1 00:55:23.441524 ARP, Request who-has 192.168.55.114 tell 192.168.55.1 ... continues for minutes with no response from the box ... The box does not respond to any ARP, does not send new DHCP, does not contact NFS (port 2049 or 111). It is as if the kernel never actually starts — or it starts but hangs so early that no network driver comes up. NFS server stats — zero kernel activity: $ sudo nfsstat -s Server rpc stats: calls badcalls badfmt badauth badclnt 0 0 0 0 0 Confirms the kernel never reached NFS root mounting. WHAT I HAVE TRIED Tested multiple combinations, all fail the same way: — 3 different DTBs: rk3528-evb1-ddr4-v10.dtb, rk3528-evb2-ddr3-v10.dtb, and the extracted Android DTB (which matches exactly: "Rockchip RK3528 EVB2 DDR3 V10 Board"). — 4 console configs: console=tty0, console=tty1, console=ttyFIQ0,1500000, and combinations. — With and without initrd (both uInitrd and no initrd). — USB card reader with microSD for rootfs (UUID-based mount). — NFS rootfs (CONFIG_ROOT_NFS=y confirmed in kernel config). — Various bootargs: earlycon=uart8250,mmio32,0xff9f0000, ignore_loglevel, panic=10, rootdelay=5.

THE DIAGNOSTIC ROADBLOCK — UART I cannot use UART for debugging. My board has DEBUG pins marked (TX/RX/GND/VCC near the WiFi module) but UART output is pure garbage at every standard rate (115200, 460800, 921600, 1500000). I suspect either: the DEBUG pins are poorly soldered on this unit, the UART configuration is different from what Ilya documented, or the pins are actually for a different UART or purpose entirely. Without readable UART, I am completely blind to what happens after U-Boot's booti command — whether the kernel panics, hangs on early init, or starts silently. MY QUESTIONS 1. Is PXE/TFTP network boot actually expected to work on this U-Boot 2017.09 from Rockchip? The bootcmd_pxe in this U-Boot is: run boot_net_usb_start; dhcp; if pxe get; then pxe boot; fi Has anyone successfully booted Armbian this way on RK3528? 2. Is there a known issue where Ilya's U-Boot + Armbian kernel don't hand off properly? Is there a specific bootm/booti command format required that PXE might not follow? 3. Could the issue be that the Armbian kernel expects specific arguments (like androidboot.* or bootloader-specific init params) that my PXE append line does not provide? 4. Are there any known-working examples of Armbian RK3528 TV-box boot that do NOT rely on on-device storage (microSD/USB flash)? 5. Given that U-Boot runs and gets DHCP fine, all files transfer via TFTP fine, file formats are correct, but the kernel is silent after booti — is this a known class of problem with a known solution besides UART?
