I am trying to set up Tinker Board headlessly as I don't have access to a wired keyboard and mouse.
One method I know that works for Raspi is by creating an SSH file while setting it up and a wpa_supplicant.conf file to provide wifi details. I have flashed the latest Tinker OS v2.2.9 onto the eMMC present on the board as per the instructions. But, in this case I am not able to access the drive once flashed (Contrary to raspi setup).
Is there a way to set it up headlessly?
Thank you for taking out time to read this and helping out.

I have an App that needs to detect, if a USB Storage device is getting mounted. Can i simulate the mounting of an USB Storage Device while the Emulator is already running? This way i can debug the behavior of my app.
As i know, for registering the mounting and unmounting of the USB Storage Device i can use the StorageVolumeCallback(). What do i have to do to write a simple .txt File to that attached USB Storage Device?
Im having trubble to create a StorageManager inside my ViewModel because i do not have access to the Context.
Im thankful for any Tipp related to USB Storage Management at all.
Info:
API Version: 31
IDE: Android Studio
Language: Kotlin
Edit:
So i do not necessarily need to have a external usb drive mounted at startup. If its possible with adb it would be great if i could just forward a usb Pendrive to the running emulator when i need it. Something like adb connectUsbDevice -deviceid=****,vendorid=***
There isn't a .NET library I'm aware of which can do this. However, please refer to this post where the brilliant answer shows how to do this interfacing with the Win 32 API.
How do I disable a system device programmatically?
You'll need a combination of this, and a WMI query to find an attached PnP device of type storage. As a clue:
using (var searcher = new ManagementObjectSearcher(#"SELECT * FROM Win32_USBHub"))
{
collection = searcher.Get();
}
Change Win32_USBHub to the correct class if this isn't giving you what you're looking for.
EDIT: Be warned. If you're disabling storage devices, make sure they're not in use. That's what the "Safely remove USB" option is for in Windows.
Another option, if you don't need to emulate this in code, use a real USB storage device inserted in the system and use PowerShell to get, disable, and enable the device.
The Cmdlets you'll need are:
Get-PnpDevice
Disable-PnpDevice
Enable-PnpDevice
So, my knowladge in embedded development is quite bad and now I am trying to receive some data from PC inside my MCu STM32F429IGT6 which is on WaveShare Core4X9I dev-board and send it back via USB Virtual COM Port.
I realized how to set up connection from MCu part and I even see connected device from Windows 10 Device Manager but... it appears as STM Device in DFU Mode
I have tryed already to install drivers from ST for such things but they are useless and official documentation says that they are not needed for Windows 10.
I have been following tutorials where guys just clicked several times inside Cube MX, generated code and VCP worked out of the box.
The question is what am I doing wrong? I don`t even know what information you might ask for thats why I created GitHub repo: https://github.com/dessy4oko/stm32f429-vcp-appears-as-dfu
And this is events from Device Manager of Windows 10 (translation from ru lang):
Device USB\VID_0483&PID_DF11\305233703237 is running. code 410
Device USB\VID_0483&PID_DF11\305233703237 is configured. code 400
Device USB\VID_0483&PID_DF11\305233703237 have not been moved due to partial or ambiguous matching. code 442
Device USB\VID_0483&PID_DF11\305233703237 requires further installation. code 430
Thank you for any information about my mistakes.
STM32 starts in DFU mode if BOOT-pins are pulled accordingly:
"System memory" means embedded bootloader, DFU in this case. You need "Main Flash" to run your app.
Check jumpers and switches on your board. Refer also to the AN2606 app note for complete information.
I have recently bought a USB, which is initially formatted using exFAT. Then I tried wiping it off and format it with ext4. But then, Linux Mint 20 doesn't seem to be able to mount it. When I checked the "disks" utility, the USB appeared, but it just displayed the loading loop. I tried to cancel the mount job, no luck either. Then I tried a live Linux Mint 19, also can't open the USB, so this is clearly not a problem with my existing computer.
Then I booted up my Windows copy (dual boot with Mint 20), plugged the USB in, formatted it to exFAT, and Windows can then open it. Then I boot up Mint 20 and live Mint 19 and both can open it. So my question is, do USB manufacturers restrict the type of filesystems a USB can have? I have never heard of this phenomenon, and can you give me some source to read more?
So I have dug into this a whole lot for the past few days and I think I know what's wrong. I tried to create an ext4 partition, didn't work. I then tried to fix it using fsck, also no dice. Then I tried to create an ext4 partition with less size (60GB), and then it works, with no corruption. It turns out that I just got scammed by the manufacturer.
I attached a PlayStationEye USB mic/camera to my pi 3 and was able to get the microphone working with arecord with commands such as arecord -D plughw:0,0 -f cd ./test.wav. My ~/.asoundrc is identical to the file shown here here.
However, when I try to use the mic through the browser it will not work. I tried various websites with no luck. My end goal is to use this mic to do speech recognition via some platform but one step at a time. Any suggestions as to how and begin to start troubleshooting this? Chromium does show the correct default devices in the settings.
I'm at a total loss and there is little to nothing I can find out there. For examples this post does not apply because the browser certainly sees it. Could it be a latency problem of some sort?
If it works with "arecord" command, you should be able to capture the audio on the web browser as well.
You should check your Microphone setting under the Chromium Content Privacy Setting and make sure you select your USB Microphone in the drop-down options.
All the best.
I cannot connect to my beaglebone black via ssh or usb,
I could connect via ssh/ethernet before I edited a file, and rebooted.
I thnink the file I changed was uEnv.txt and I think I commented out the line about HDMI
Any ideas? do i just need to reinstall the debian OS? via the memory card?
thanks for your help.
If it really was the uEnv.tx-file you don't need to reflash your img.
You can edit the uEnv.txt file again (easly with the plugged USB and explorer). If you comment things out in this file, the driver can't work properly. If you can tell me your img version (that's very usefull if you write it by every question down) I can show you the unmodified uEnv file.
You can easy also google that file.
An alternative way is to reflash the img. Recommendable for new BBB / Linux users. The img an guide is available at beaglebone.org
I hope I answered your question, otherwise write again!
