Thank you for your answers. I never managed to properly get dhcpcd and wpasupplicant to work but I noticed that wpa2-enterprise networks works well with the ubuntu + mate environment supplied on the raspberry pi website. It looked like it was using network manager so what I did was go back to raspbian lite and run:
sudo apt install network-manager network-...
I'm new on this forum so I can't write a comment on Stephane Bourque's answer and I must create a new answer. I'm writing I2C slave just like you and I've found a solution regarding an uncontrolled shift on xfer.txBuf register, and that solution is to read the entire "txBuf" that is BSC_FIFO_SIZE (512 bytes) long on the master side. I've just ...
It may be possible that wpa_supplicant is modifying its configuration file for some reason to permanently store configuration changes but with the change it will not work anymore. This is manged by the option:
Set this option to 0. This will wpa_supplicant prevent to change its configuration file so you have excluded this possebillity.
You can either install the GUI desktop stack and use whatever you like there, or else you need something that runs on the kernel's software framebuffer. I'm not sure if this is what the camera preview window does, since it was written for the Pi it probably uses custom GPU code.
The only framebuffer image viewer I'm aware of is fbi:
OK, lets get your Unit step by step. First to the error message. It says what's wrong:
' cd /home/pi/file_directory source /home/pi/file_directory/venv/bin/activate; \"
It starts with a single quote but do not end with one. That's the Unbalanced quoting. But we will not take any effort to correct the bash script because we will use systemd options to ...
For a quick overview you can show the statistics of an interface with, for example:
rpi ~$ ip -stats -stats link show wlan0
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DORMANT group default qlen 1000
link/ether dc:a6:32:7f:38:92 brd ff:ff:ff:ff:ff:ff
RX: bytes packets errors dropped overrun mcast
Note, this is not a complete answer. I've encountered compile-time errors when building the Hycon sources, and decided to switch to a different solution instead of fixing their code.
This is how you would normally install such driver:
Copy hy46xx_ts.c and hy46xx_ts.h to the drivers/input/touchscreen directory
Modify drivers/input/touchscreen/KConfig, append ...
