koutheir Posted September 22 Posted September 22 (edited) I downloaded and flashed the three images of Armbian 24.8.1 (Noble GNOME, Ubuntu 22.04 Jammy and Debian 12 Bookworm) on the Banana Pi M7, connected to the computer via serial console. The three images are these: Armbian_24.8.1_Bananapim7_noble_vendor_6.1.75_gnome-kisak_desktop.img Armbian_24.8.1_Bananapim7_jammy_vendor_6.1.75_kde-neon-kisak_desktop.img Armbian_24.8.1_Bananapim7_bookworm_vendor_6.1.75_cinnamon-backported-mesa_desktop.img For each image, I booted and logged the board output. The board fails to successfully boot and instead gets stuck in a boot loop. I then mounted the armbi_root partition and edited the file armbi_root/boot/armbianEnv.txt to set verbosity=7, in the hope of getting more useful information from the kernel. I retried booting the board, and I observed the same boot loop, but this time with more kernel logs. The serial outputs of the failed boots are here: Armbian 24.8.1 Noble GNOME: noble.log (see attached files) Armbian 24.8.1 Ubuntu 22.04 Jammy: jammy.log (see attached files) Armbian 24.8.1 Debian 12 Bookworm: bookworm.log (see attached files) I’m not sure why the kernel decides to reboot everytime, but I’m sharing the information in case it is useful to someone.

Igor Posted September 22 Posted September 22 How I did testing: 1. Download https://dl.armbian.com/bananapim7/Bookworm_vendor_minimal 2. Flash and boot (by using USB Imager - try that perhaps) 3. Boot logs: https://paste.armbian.com/vucakunoko Next: testing the same image just to make sure: https://dl.armbian.com/bananapim7/Noble_vendor_gnome-kisak Armbian_24.8.1_Bananapim7_noble_vendor_6.1.75_gnome-kisak_desktop.img Boot logs: https://paste.armbian.com/jobavuqeza My PSU is lab, no PD. Problem is 100% not on our side. 0 Quote
koutheir Posted September 23 Author Posted September 23 I downloaded and flashed both images, then I set verbosity=7, then I booted each on the board. I'm powering the board using a USB-C 30W power supply. I don't know of another way to power the board. Both images failed to boot on my board, and I attached the serial console logs for reference.

koutheir Posted September 23 Author Posted September 23 (edited) As I mentioned here, the Armbian unofficial 24.5.0 provided in the Banana Pi M7 documentation boots fine and works as expected, provided that the package linux-dtb-legacy-rk35xx does not get upgraded. For some reason, the version 24.5.0-trunk of that package works fine, but upgrading it to version 24.5.1 breaks the boot process. For the moment, I placed an apt hold on that package, in order to avoid upgrading it by mistake. Upgrading all other packages does not cause boot problems. I'm trying to analyze the situation, so I captured the serial console output of that image booting before upgrading linux-dtb-legacy-rk35xx (so version 24.5.0-trunk) and after the upgrade (so version 24.5.1). Of course, the second boot fails, but I captured all u-boot and kernel logs. I removed the kernel timestamps in order to make the comparison easier. I then sorted the log files (yes, alphabetic sort), and looked for the lines that are different. I noticed that the u-boot log is almost the same. The differences are in the kernel logs. Here are the log lines that are emitted only during the broken boot process: OF: graph: no port node found in /i2c@feab0000/fusb302@22 OF: graph: no port node found in /i2c@feab0000/fusb302@22/connector OF: graph: no port node found in /i2c@feab0000/fusb302@22/connector OF: graph: no port node found in /i2c@feab0000/fusb302@22/connector ... rk-pcie fe180000.pcie: PCIe Linking...

Solution koutheir Posted September 23 Author Solution Posted September 23 I found and fixed the problem, and of course, it is the PSU. TL;DR: use a USB-C PD 2.0 power supply that can provide 35W for a single USB-C port. I bought the Banana Pi M7 from this Amazon page, and the seller provides a power supply, with the board, that can only provide up to 20W of power. Even though the board specification says "Power Input: USB Type-C PD 2.0, 9V/2A, 12V/2A, 15V/2A", which implies that the board can require up to 30W of power. This caused most official images (Armbian and otherwise) to fail to boot. I happened to have a USB-C charger that can provide 35W of power, so I tried that instead, and it basically solved the whole problem. I tried multiple Armbian official images and they work as expected. Thank you for your help! I hope this helps someone. 1 Quote
armsom-jackson Posted Friday at 08:20 AM Posted Friday at 08:20 AM The loop boot may be caused by not opening pd in the uboot stage. It has been fixed now https://github.com/armbian/build/commit/a46a7cfaf5216ac2dad33c5f129e7771e35d7c55 0 Quote
