mxq pro 4k 5g allwinner h313 can't sd card boot
Yes, there are some updates. First of all I've found two uart interfaces. See attached photos. Two test points located on the bottom side of pcb is for SoC uart, and two near wifi interface is for TXW901 uart. Tx and Rx as on attached pics. Furthermore, AFAIR, powering on while holding SoC Rx low forces SoC to search for bootable usb flash drive. Second is my modified android (not armbian!) firmware v.0.2. You can download it using link in my message above. Changelog also there. Major changes: Google Play is working again, improved wifi stability. Third, there are Linux drivers available for TXW901 (Wifi interface). You can get it here: https://www.taixin-semi.com/Product?prouctSubClass=66 (registration is required, however, all that you need to register is valid e-mail). So, potentially, one could compile armbian image for this box (integrate wifi driver into armbian, obtain memory settings through SoC uart, configure and compile kernel and boot image). -

CPU won't run freq 1512000 on armbian. Running perfectly on any other distro.
Hi, my first step would be comparing the opp nodes in the device trees of both Armbian and any other distro that allows the faster speed. Perhaps the necessary node is just missing. -

SB Gadget Serial (g_serial) not working on Noble 6.12.51 build NanoPi Duo
I built an unofficial Armbian 6.12.51 (Noble) image using the build tool: Armbian-unofficial_25.11.0-trunk_Nanopiduo_noble_current_6.12.51.img I am trying to get the micro-USB port to work as a USB serial gadget (g_serial / libcomposite). What I have done / observed: g_serial and libcomposite modules are loaded: lsmod | grep g_serial g_serial 12288 0 libcomposite 49152 2 g_serial,usb_f_acm ConfigFS is mounted: mount | grep configfs configfs on /sys/kernel/config type configfs (rw,nosuid,nodev,noexec,relatime) UDC exists: ls /sys/class/udc/ musb-hdrc.2.auto Gadget folder does not exist: ls /sys/kernel/config/usb_gadget/ # output: empty Trying to manually bind a gadget fails: echo musb-hdrc.2.auto | sudo tee /sys/kernel/config/usb_gadget/g1/UDC # Output: tee: UDC: Device or resource busy Current UDC mode: cat /sys/class/udc/musb-hdrc.2.auto/device/mode b_idle There is no /sys/class/usb_role/usb0/role available to force device mode. This setup works fine on Jammy kernel, same cable, same SD card rootfs. Problem: The OTG controller comes up in b_idle mode, preventing the USB gadget from binding. /dev/ttyACM0 never appears on the host PC. It seems like the device tree / overlay for Noble 6.12.51 is not configuring the OTG port for peripheral mode. What I want: USB serial gadget (g_serial) working over the micro-USB port on Noble 6.12.51 build. Any advice on the correct overlay or device tree modification needed to bring the OTG port into device mode at boot. Extra info: CONFIG_USB_CONFIGFS_SERIAL=y in kernel CONFIG_USB_LIBCOMPOSITE compiled as module Micro-USB cable confirmed working with Jammy kernel Modules: libcomposite, g_serial, usb_f_acm present Thanks in advance for guidance! -

CPU won't run freq 1512000 on armbian. Running perfectly on any other distro.
Hi, I have an Orange Pi Zero 3 with Allwinner H618 (1GB RAM version). The CPU specs say up to 1.5 GHz (1512000 kHz), and it hits that fine on other distros (like official Orange Pi Ubuntu images or Debian builds). But on Armbian, max freq is stuck at 1416000 kHz, even on latest kernels. Board: Orange Pi Zero 3 (H618, 1GB RAM) Armbian Version: Armbian Bookworm (fresh SD flash, ran armbian-upgrade after boot) Kernel Versions Tested: 6.12.43-current-sunxi64 6.12.47-current-sunxi64 6.15.4-edge-sunxi64 6.16.8-edge-sunxi64 (current edge, i think) What happens: scaling_available_frequencies only goes up to 1416000. With governor=performance and MAX_SPEED=1512000 in cpufrequtils, under load (stress --cpu 4) it never goes above 1416000. No throttling (temps <65°C with heatsink, armbianmonitor clean). dmesg says "sun50i_cpufreq_nvmem: Using CPU speed bin speed0" and seems to fallback to H616 limits, cutting OPP table. Tried: armbian-config to switch kernels. Edit /etc/default/cpufrequtils (GOVERNOR=performance, MAX_SPEED=1512000). extraargs=cpufreq.default_governor=performance in /boot/armbianEnv.txt. No DTB changes (don't want to break stuff). On non-Armbian (e.g., Orange Pi's Ubuntu 24.04), 1512000 shows in available freqs and runs full speed. Armbian works for basics (WiFi, Ethernet, local server), but this caps perf by ~7%. Attached outputs from 6.16.8-edge. How to unlock full OPP for H618 speed bin 0? Thanks. By the way, this is my first time using Armbian and posting on the forum, so sorry if anything's off. Zaplemon freq_info.txt dmesg_cpufreq.txt armbianmonitor_load.txt uname.txt -
