I have been recently trying to flash the google coral dev board.
dmesg | grep ttyUSB [ I get the expected output]
[ 6437.706335] usb 2-13.1: cp210x converter now attached to ttyUSB0
[ 6437.708049] usb 2-13.1: cp210x converter now attached to ttyUSB1
screen /dev/ttyUSB0 115200
Screen goes back (blinking cursor)
But after I power up the dev board, no welcome message or anything comes up on the console, it just remains blank. I am not sure what the issue is. Any help would be highly appreciated. Thank you.
I believe you have reached out to us privately via the coral-support channel and this issue was resolved.
Just wanted to add in for other to reference, this is a rarer issue that we've faced, but we were able to get the board working again after a reflash with an sdcard recovery image.

I am using speech framework in mac-catalist application its working correctly in iOS but it doesn't work on some of the Mac devices. It's working fine on system A its not working on system B but all the logs (debug console) are same even settings/permissions are same. Code is correct as it's working on some of the devices so it couldn't be wrong.
Could anyone please help me to track the issue ?
Thanks in advance.
While you've verified that both have the same settings / permissions have you ensured the accessibility within the 'System Preferences' has been granted access for your specific application? Sometimes this can be found within 'System Preferences' -> 'Security & Privacy' -> 'Accessibility'.
Sometimes running your program via sudo ./your-application can prompt this security requirement, so attempt running the application in sudo and checking the security settings once more.
How can I hide or lock "Emergency mode" found in the Power Menu on the Samsung (Android 7.0) without rooting the phone?
Any assistance would be greatly appreciated!
Thanks
I found a way to disable Emergency Mode without root. Enable Developer Mode and USB debugging mode then on a terminal input the following line of code:
adb shell pm uninstall -k --user 0 com.sec.android.emergencymode.service
Hope this helps!
Thanks,
There are no ways to do that without root, because the power menu options are "hardcoded" inside the framework rom Resource values and you need root privileges to edit it :)
Actually i want to build one iPhone app which will use PJSIP library.
i have downloaded latest pjsip available. and also commandline tool.
and i am successfuly able to build PJSUA app on my iPhone.and i can see Black screen with PJSIP logo and label displaying- telnet to 192.168.. :2323.
but i dont see any console ,where i can enter commands,as mentioned in the pjsip document.
I Just need some initial setUp help .Like how to send command etc ,if anyone can.
it will be very grateful,if you can share some experince and knowledge with me.
I've start same things in meanwhile ago too. Just open up your cmd or terminal and type in following command:
telnet 192.168.1.40 2323
and it should be working. Good luck!
I didn't think it would be so catastrophic when I typed
JavaLoader -usb wipe -a
into the command line with my blackberry 8800 test device. It reboots with a 507 error that I can't get rid of.
I have Blackberry Desktop Manager 4.6, which is normally what I use to upload my test apps, but this time I go to Application Loader, hitting start gives me that dialog box that shows me the list of 1 USB connection "PIN: xxx" with a password field (which I have no idea of,) then it says "connecting to boot ROM" then stops at the message: A connection to the device can not be established...
Now is there a hard physical way of resetting my blackberry 8800, please?
507 is a missing COD file that is required. Your best bet is to reload the OS. Here's some instructions from the BlackBerry forums:
How To Reload Your Operating System
I am working on a web development project that I want to make sure works well on the BlackBerry browser. As part of both testing and documentation, I want to be able to take screenshots of my application and was wondering where to start.
I see there are a couple of pay applications on BlackBerry App World when I search for screenshot, but I am looking for recommendations or other options. Specifically, I have a Bold 9700 (v5.0.0.296, platform 5.1.0.83).
It appears this feature is built into the iPhone, according to the iPhone User Guide.
Take a screenshot of the iPhone
display: Quickly press and release the
Sleep/Wake and Home buttons at the
same time.
You may want to write you're own app or service to make screenshots.
Use
Display.screenshot(Bitmap bitmap)
or
Display.screenshot(Bitmap bitmap, int x, int y, int width, int height)
Note: you should sign app to use this api
If you have the developer tools installed, you can use "javaloader -u screenshot file.bmp" to capture a screenshot. Otherwise, the easiest way is to install a PC app called Master Control Program which has the capability to capture screenshots as well (as long as you have your device connected to your PC with a USB cable).
I get BlackBerry screenshots in two ways:
-On real devices I connect them to my PC over USB and run javaloader -u screenshot image.bmp from the command line (as Marc says, it's included with the developer tools).
-The BlackBerry Simulator makes it easy to take screenshots by pressing F3 (or choosing Edit -> Save LCD Snapshot from the menu, note you can choose to save directly as a .png, which is handy). You can change which phone model to simulate based on the SDK you have installed. For the 9700 I think you will need the V5.0 OS SDK (I haven't tried that yet), which you can get from here.

I've also heard of something called BB Stream that will actually stream the blackberry screen to your PC. Can't find it anywhere though.
This is a very good guide
