I'm trying to get a Rock64 board working with a wifi USB dongle, sold as RTL8188 and which is in fact a 8188eu. I use the latest armbian-buster as downloaded a few days ago. The dongle appears in dmesg when plugged in, but no module is loaded. I can manually load the 8188eu module and get no errors, but no wifi interface appears. Ifconfig, iwconfig and nmtui don't see anything they could use for wlan. I have installed the firmware-realtek package as well, it made no difference. I can get the module 8188eu autoloaded at boot, but that doesn't change the non-availability of a wlan interface. Any help appreciated. I have posted the armbianmonitor -u output in the required field. ( here it is again: http://ix.io/2Dee )

Don't think so, the connectors are snug on both power supplies, and the boards do start uboot but stall when the kernel kicks in. Maybe there's a momentary power demand increase that the smaller PS can't cope with and it stalls the kernel.

I'm not using any USB cables for power. I use dedicated power supplies with barrel connectors. With a 2.5A power supply, the boards don't run. With a 5A supply, they do. But I agree they're running cool. So maybe my 2.5A power supply is faulty.

Huh, I became suspicious that it may be a power problem when the kernel wouldn't load correctly with the serial monitor attached, so I changed the power supply from a 2.5A one to a 5A one, and now all boards boot correctly. Please ignore the above. I didn't realize that these boards were quite so power hungry. It's funny because the CPU doesn't get even slightly warm while doing an update. I wonder where all that power is going.

I have several Orange Pi One and Orange Pi PC boards (the original ones, H3-based). I have downloaded the latest Armbian release for them Armbian_5.91_Orangepipc_Debian_buster_next_4.19.59 and imaged several SD cards in Linux with dd. The cards are all class 10, some are Sandisk and some are Samsung. I am using a 2.5A power supply for the boards. For all the boards and all the SD cards I get the same result. U-boot starts, gets to the point of loading the kernel, clears the screen then displays "Loading, please wait" then "Starting version 241" and stalls there. Nothing else happens no matter how long I wait. If I power the board off and then back on, the same thing happens. This happens with 3 different boards (one Orange Pi One and 2 Orange Pi PCs), and 5 different SD cards. The SD cards are all 16GB, class 10, 3 are Sandisk and 2 are Samsung. Any combination of board+card gives me the same result. The way the cards are written is with: dd if=Armbian_5.91_Orangepipc_Debian_buster_next_4.19.59.img of=/dev/mmcblk0 bs=4M I have used the same approach with Armbian for the Odroid-C2 with the corresponding version of Armbian, and that worked well. If I connect any of the boards to the Linux PC via USB-TTL adapter and use a serial console, the boards freeze before loading the kernel. Here is the serial console output.

Yes, that is exactly what I tried using, and why I said that the documentation doesn't apply to the current state of ALSA. For instance,anything I put in /etc/asound.conf is thoroughly ignored and doesn't have any effect; same for /usr/share/alsa/alsa.conf; /proc/asound/modules doesn't exist anymore, etc.

From the CLI that is. I plan on using the OPi as a headless MIDI processor, and I'd like to be able to switch remotely the audio output of ALSA between the default audio-out, the HDMI out and a USB sound card (CM108-based, tested working with the current kernel). ALSA documentation isn't well maintained, most of it is old and doesn't correspond with the current state of the software (config files locations and names, contents etc). I tried various examples I found on several bulletin boards, but none really worked since Armbian seems to do things a bit differently. So I'm asking here: on Armbian, how do I switch remotely the output audio device in ALSA? No remote desktop, just ssh/CLI.

Also, after compiling the kernel again, when I try to install the packages it gives me sudo dpkg -i linux-dtb-odroidc2_5.06_arm64.deb (Reading database ... 48160 files and directories currently installed.) Preparing to unpack linux-dtb-odroidc2_5.06_arm64.deb ...

BTW my problem yesterday with not being able to connect to the C2 with my self-built image - it was a power supply problem. With a good PS it boots just fine. However apt-get update fails with W: Failed to fetch http://apt.armbian.com/dists/jessie/InRelease Unable to find expected entry 'main/binary-arm64/Packages' in Release file (Wrong sources.list entry or malformed file)

64bit. Having a pure 32bit image is only feasible for a headless server-type install, since some drivers (notably the mali-fbdev) are 64bit only AFAIK.

Well I managed to build the image after the change. I did notice some errors during the build (unfortunately I can't copy/paste as I did the building in a real console not a xterm) 1. unsupported ioctl, cmd=0x5331 after update-initramfs 2 missing cp destination file operand after installing RT8192 external driver I wrote the image to a card, plugged it in and connected the odroid to my router via cable, the blue LED blinks meaning it's alive, but it makes no DHCP request to the router. I don't have a display available right now to plug it into, I'll try that tomorrow.

I tried to compile a Jessie desktop image for the C2 on my Xubuntu 14.04 laptop. The compile script fails at the u-boot image. The only changes I made to compile.sh were setting both KERNEL_CONFIGURE and KERNEL_KEEP_CONFIG to "yes" because I wanted to add some modules to the default config. But of course the point where it fails is before it even gets to that part.

Well, so far it seems stable. I have checked the barrel connector and solder joints seem good, no play and very little resistance across. I have found a dual USB charger (one of the ports is high-current, 2A). I'm feeding the current from the 2A plug through the barrel connector, and the other port (1A) through the GPIO. Works well so far, but for some reason if I use just one or the other it doesn't boot correctly. It definitely doesn't use nowhere near as much current as the charger is rated for, and it does heavy tasks (compiling a whole game) without crashing.

I stand corrected; I hadn't actually looked close at how he makes the backup in the first place. But it still wouldn't work if there is more than 16GB of data, simply because there isn't enough space on the 16GB card to hold it all.
