Failed to start build jar file - Failed to load class "org.slf4j.impl.StaticLoggerBinder"

Issue arrises when trying to load final compiled build on the raspberry pi

What version of Raspberry Pi are you running on?

[lukehutch]

Also, please try running this project as root -- that may solve the problem.

[TheNopePlant]

Running RPi Zero W. 2017 date code, not sure of revision of board however. EDIT: It is a V1.1 board

Running as root does launch, however it will not start as root on boot

[lukehutch]

OK, so running as root has no problems then? Related bug: https://github.com/Pi4J/pi4j-v2/issues/60

Here are my notes for how to install the USB copier project, and get it running at boot. Sorry that this is not documented yet!

On the build machine:

• git clone https://github.com/lukehutch/Adafruit-OLED-Bonnet-Toolkit.git
• cd Adafruit-OLED-Bonnet-Toolkit ; mvn install ; cd ..
• git clone https://github.com/lukehutch/usb-copier.git
• Then copy target/usb-copier-0.0.2-jar-with-dependencies.jar to /home/pi on the Raspberry Pi.

On the Raspberry Pi:

• Run raspi-config and enable Interfacing Options -> Advanced Options -> i2c
• apt-get install openjdk-11-jdk wiringpi pigpio nano udevil
• sudo nano /etc/cmdline.txt
  • add kernel option: (otherwise GPIO handler cannot access /dev/mem)
  • iomem=relaxed
• sudo nano /etc/config.txt
  • add options:
  • dtparam=i2c_arm=on
  • dtparam=i2c_baudrate=1000000
• Extract libpi4j-pigpio.so to /home/pi (this is needed due to a bug in the library loading code)
  • cd ; unzip -j /path/to/usb-copier-0.0.2-jar-with-dependencies.jar lib/armhf/libpi4j-pigpio.so
• Add to /etc/rc.local :
  • sudo bash -c 'nohup java -Dpi4j.library.path=/home/pi -jar /home/pi/usb-copier-0.0.2-jar-with-dependencies.jar &'

Some steps may need to be tweaked a little, I'm not sure. Please let me know if this works.

1 issue when loading as root manually.

pi@toastdoom:~ $ sudo java -jar usb-copier-0.0.2-jar-with-dependencies.jar [2021-10-02 10:23:23 592] [INFO ] Initializing Bonnet SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

[2021-10-02 10:23:28 851] [FINE ] Opening I2C bus 1 [2021-10-02 10:23:29 051] [FINE ] Opened I2C bus 1, device 0x3c`

However this does load the display, mount drives and allows me to copy without any issues.

Have since added the line to /etc.rc.local (see below):

!/bin/sh -e rc.local This script is executed at the end of each multiuser runlevel. Make sure that the script will "exit 0" on success or any other value on error. In order to enable or disable this script just change the execution bits.

By default this script does nothing. Print the IP address _IP=$(hostname -I) || true if [ "$_IP" ]; then printf "My IP address is %s\n" "$_IP" fi

exit 0

sudo bash -c 'nohup java -Dpi4j.library.path=/home/pi -jar /home/pi/usb-copier-0.0.2-jar-with-dependencies.jar &'

This still does not load on boot. Is it possible that the sudo bash script needs to be loaded before exit 0

[TheNopePlant]

Update:

Can confirm that you need to have sudo bash -c 'nohup java -Dpi4j.library.path=/home/pi -jar /home/pi/usb-copier-0.0.2-jar-with-dependencies.jar &' before exit 0 in the /etc/rc.local file.

Have since successfully booted to the usb-copier

[lukehutch]

Yes, correct, exit ends the script, so you need to put this before exit 0.
