Using armbian 5.51 debian stretch I found the following errors in the system log from the reboot after a system crash. At least Apache failed to start. root@hc1:/var/log# journalctl | grep "/var/log" Jul 09 12:13:16 hc1 apachectl[970]: (2)No such file or directory: AH02291: Cannot access directory '/var/log/apache2/' for main error log Jul 09 12:13:16 hc1 apachectl[970]: (2)No such file or directory: AH02291: Cannot access directory '/var/log/apache2/' for error log of vhost defined at /etc/apache2/sites-enabled/nextcloud.conf:7 Jul 09 12:13:16 hc1 apachectl[970]: (2)No such file o

Still - or again - I'm getting this error. Err:13 http://beta.armbian.com stretch Release 404 Not Found Reading package lists...

Quick test results from me with DCDC3=1.30V ( CONFIG_AXP_DCDC3_VOLT=1300 ). Again seems stable with 432 MHz. (lima-memtester still running). Two immediate freeze/crashes of lima-memtester with 384 Mhz: root@cubietruck:~# ./lima-memtester 1536M This is a simple textured cube demo from the lima driver and a memtester. Both combined in a single program. The mali400 hardware is only used to stress RAM in the background. But this happens to significantly increase chances of exposing memory stability related problems. Kernel driver is version 14 Detected 1 Mali-400 GP Cores. Detected 2 Ma

Here we go - zip contains both 384MHz and 432MHz u-boot at DCDC3=1.30V ( CONFIG_AXP_DCDC3_VOLT=1300 ). cubietruck_uboot_binary_DCDC3_13v_20170219.zip

Thanks - you are right. I saw the crash during unload of the wireless kernel module but wouldn't guess that it was related. Commenting the line ap6210 in /etc/modules fixed it. PS: And even better - disabling WLAN also fixed that 10-20 seconds delay during ssh login

Installed armbian 5.25 jessie legacy from scratch. No changes to network configuration. Cubietruck: - eth0 (wired ethernet) - DHCP - works fine - WLAN0 - driver is loaded during boot - but not used at all Default /etc/networking/interfaces config: allow-hotplug eth0 iface eth0 inet dhcp auto lo iface lo inet loopback Reboot hangs forever during shutdown while executing the following stop (!!) skript: [ *** ] A stop job is running for LSB: Raise network interfa...13s / no limit) Tried both possible solutions to define a timeout of 15 secs from http://unix.stackexchange.com

I've compiled from mainline u-boot yesterday (13/02/2017) with unmodified cubietruck defconfig (CONFIG_DRAM_CLK=432 ) and another version with reduced clock speed (CONFIG_DRAM_CLK=384) that is used in armbian. I guess it's the same version that is used in armbian 5.25 (but can't be sure). Please find attached a zip with both binaries. cubietruck_uboot_binary_20170213.zip

That would be great. I would happily test DRAM clock settings more efficently.

From here: http://linux-sunxi.org/A10_DRAM_Controller_Calibration It is required to have the sunxi-3.4 kernel (specifically for for the mali kernel module). The mainline kernel is not supported yet because it is lacking in the graphics department.

Folks, I did some more testing with armbian 5.25 (jessie legacy) on my "problematic" cubie truck: - again unstable with armbian u-boot 5.25 Package ( crash after few seconds running lima memtester) - stable with own compiled current mainline u-boot with default cubietruck defconfig (DRAM clock speed: 432 MHz) - completed 35 runs of lima memtester over night without problems - but also unstable with current mainline u-boot at DRAM clock speed 384 MHz ( crash after few seconds running lima memtester) So I'm quite sure now, that one of my two cubietrucks is a rare (??) exemplar tha

You are right - I use the legacy 3.4.x kernel. So skip editing boot.cmd with mainline / vanilla kernel - I changed my post above. My system hang during kernel boot without the bootm_boot_mode line. Compiling u-boot is completely independent from the kernel that is booted afterwards. So the compiled u-boot should work for you too. Anyway - fiddling with u-boot can make your system stop booting at all. This is why I mentioned to have an SD card backup before doing so...

Afraid a monitor in the cellar won't be good enough - there is no easy way to see u-boot boot messages. These are visible on a serial console only ( see http://linux-sunxi.org/Cubieboard/TTL ). dmesg logging only starts after loading the Linux kernel.
