-in such way, I'm trying to Open serial device, but not able to open that serial device getting Error No such file or directory.
-I have use Same binary and run it on my other system and it is working fine.
Note- I have installed same Cygwin packages on both the system.

I use vscode with Arduino extension on Ubuntu 22.04.1 LTS which had worked well until now.
If I'm trying to upload I'm getting the error:
avrdude: ser_open(): can't open device "/dev/ttyACM0: Permission denied"
When trying to upload a sketch to an Arduino Micro.
Then I tried it with the Arduino IDE 1.8.19 which produces the same error.
I have added my user to the dialout group even though it had worked before without that (and I restarted after that).
If I change chmod of /dev/ttyACM0 that does not help at all.
If I do:
~ $ ls -al /dev/ttyACM0
crw-rw----+ 1 root dialout 166, 0 Sep 14 00:15 /dev/ttyACM0
~ $ id
uid=1000(magraina) gid=1000(magraina) groups=1000(magraina),4(adm),20(dialout),24(cdrom),27(sudo),30(dip),46(plugdev),122(lpadmin),134(lxd),135(sambashare)
I was able to run avrdude manually with sudo
So I have now setup a rule under:
/etc/udev/rules.d named 50-myusb.rules
With:
SUBSYSTEM=="usb", MODE="0666", GROUP="dialout"
Now I'm able to run avrdude in the terminal to upload my sketch manually without sudo, but I'm still unable to run it through vscode or the Arduino IDE.
What else can I do?
It's more like a workaround but it's a solution that works for me.
Now the Arduino IDE in Version 2.0 has been released.
I downloaded it and run it.
With that version I'm now able to to upload a sketch as usual.
But sadly I could not find a solution for vscode as the Arduino extension only supports the old version for now.
Even though vscode runs avrdude from the same path as the new version of the Arduino IDE does.
It seems to me like, as if vscode has different user rights and I don't know how to change that.
sudo chmod a+rw /dev/ttyUSB0 or /dev/ttyACM0 which port used see Tools
Use case is something like this. We need to use the Bluez BT stack on linux. There is also dependency of an iOS app that controls BT testing on iOS (On mac). The execution flow triggers mounting of the file system from linux onto mac and tries to build the xcode project and use the .app file that gets generated after the build is successful
If the xcode build command is run manually on Mac directly, there is no problem
xcodebuild test-without-building -project ios_bluetooth/ios_bluetooth.xcodeproj/ -scheme
ios_bluetooth -destination id=uuid -only-
testing:ios_bluetoothUITests CONFIGURATION_BUILD_DIR=./Build/Products/Debug-iphoneos -
derivedDataPath ./ios_bluetooth/DerivedData/ arguments=TESTS_STA_BLUETOOTH_ON
From Linux, after the mount, by default it mounts to /var/root/ProjectFolder/Dependencies. Running the xcodebuild command results in issues in terms of permission. Issue can be see even if logged in as root on mac. Is there a way to circumvent this issue and get the xcode project to build? Any help in this regard is appreciated.
I am new to Linux so I have created a bootable usb drive with Linux Mint on it so that I can play around with it for a while before deciding if I want to install Linux on my harddrive.
I have created the pendrive with persistence so that I should have the ability to install software on it. However I can't seem to install anything.
I have downloaded the graphical linux postgresql installation file, given it execution permissions and then get the following error when I try to run it:
There has been an error
Error changing ownership of
/tmp/postgresql_installer_120403f9ba/lib/postgresql to root
I also downloaded the 7zip tar file, extracted it and tried to run the install.sh file. But nothing happens. Im just trying to see if I can get anything to install.
Im guessing either there's something with permissions that im not doing correctly, or it has something to do with the fact that im running linux from a usb drive.
As mentioned, im brand new to linux.
I have figured out what was required. I was trying to double click the install file from the GUI which wasn't working. I had to run it using sudo from the command line. Looks good now.
When doing a wubi install of linux from windows, the place/file where all linux info is saved is inside a "root.disk" file.
I am intending on formatting my laptop to run linux only and I can't seem to find a way to open this root.disk file from linux itself (to extract some of the files from my previous installation). Of course, it does and is able to open in windows using a certain software, but because I will only have linux on my system now, does anybody know how to open this file in linux itself? It's kind of strange that it isn't able to open with the default linux tools.
Specs:
I am using Linux Mint 12 (via wubi install). Intending on moving to a 'lighter' version of linux.
You need to mount this image before you can access it, try the following:
mkdir olddisk
sudo mount -o loop /path/to/root.disk olddisk
You should now be able to access the data inside this container.
my environment:
kubuntu : 3.2.0-generic-pae
vmware player: VMware-Player-4.0.4-744019.i386.bundle
And i have been installed it.
$sh VMware-Player-4.0.4-744019.i386.bundle
I have a problem, when i launch "menu->system->VMware Player"
it launch a window and start compiling:
[ok] Virtual Machine Monitor
[failed] Virtual Network Device
[ok] VMware Blocking Filesystem
[ok] Virtual Machine Communication Interface
[ok] VMCI Sockets
[result fail]Starting Vmare Services

Could some people tell me what's wrong ?
I suppose that there are no linux headers installed on your machine, that is why it is impossible to build the vmnet module. You must install headers and then try once again.
Ok, I've had the same problem this evening when upgrading from 4.0.3 to 4.0.4. What I've found to work is to first download the patch from this VMWare community thread - http://communities.vmware.com/thread/344213
Unzip it and then open the patch-modules_3.2.0.sh in gedit. There will be three lines at the top that read:
fpatch=vmware3.2.0.patch
vmreqver=8.0.2
plreqver=4.0.2
You have to change the plreqver=4.0.2 to plreqver=4.0.4
Then, open your terminal and run
sudo ./patch-modules_3.2.0.sh
As a side note, keep that file handy, because I found that I had to do the same thing when upgrading from 4.0.2 to 4.0.3 in Ubuntu 12.04. However, when you try the same again in the next upgrade (e.g. change the plreqver to 4.0.5 and run the script), it will say that the file is already patched and it won't work.
To get around this, you need to go to the "/usr/lib/vmware/modules/source/" folder, find the hidden file called ".patched", and delete it (easiest option is to "sudo nautilus" in terminal and hunt through the folder structure). Then it thinks that it hasn't been patched and does the process again.
Hope this gets your VMWare back up and running.
