* For a <font color='red'>'''production system'''</font> with rare changes to the file system it is recommended to boot from NAND flash. Changes to the file system require running an extra sync command (overlay_sync) followed by a proper reboot.
 
+
* For <font color='red'>'''development'''</font>, one can boot from the &mu;SD recovery card and use it - saving changes does not require extra sync actions.
 +
* Camera's software includes gcc compiler - relatively small projects can be compiled on the camera.

In the package

Fig.1a 10393 interfaces
Fig.1b Boards connections (NC393-F-CS)
Fig.1c Micro SD card for development
Range Power supply
36-72V (default) wall adapter (48V)
18-75V wall adapter (48V)
12-36V wall adapter, battery (12V)
3.3V direct, custom
  • CAT6 network cable
  • μUSB-to-USB cable
  • Recovery μSD card
  • If the camera is calibrated the calibration data will be on a separate storage media or on the internal SSD (likely /mnt/sda1)

Interfaces

See Fig.1:

GigE gigabit network
μSD micro SD card slot - boot or storage
console serial console port, use μUSB-to-USB cable
eSATA+USB 2-in-1. Connect USB or eSATA device. USB2.0 host
μUSB USB2.0 host
sync sync multiple cameras or other devices - input/output trigger signal through a 4-conductor 2.5mm audio plug with cable (example: digikey)


Power on

  • Plug in the power supply
  • Connect to LAN using the network cable

Notes

  • Boot time: ~30s
  • No extra drivers are required on the host PC to operate the camera system. Can be operated from any network device with a browser.
  • The default boot is from the on-board NAND flash. More information on available boot options and recovery boot.
  • For a production system with rare changes to the file system it is recommended to boot from NAND flash. Changes to the file system require running an extra sync command (overlay_sync) followed by a proper reboot.
  • For development, one can boot from the μSD recovery card and use it - saving changes does not require extra sync actions.
  • Camera's software includes gcc compiler - relatively small projects can be compiled on the camera.

Defaults

IP Address 192.168.0.9
User root
Password pass
  • The default IP address is set in the /etc/elphel393/init_elphel393.py.
  • If present the internal SSD will be formatted into 2 partitions:
    • /dev/sda1 - ext4 (~64-100GB)
    • /dev/sda2 - raw partition (no file system) for fast recording

Command line access

  • ssh from PC's terminal:

user@hostname:~$ ssh root@192.168.0.9

Serial console access

  • Use a microUSB-USB cable to connect console μUSB port (see Fig.1) to PC - the cable's end should be thin enough otherwise interferes with an inserted mmc (multi media card = μSD card).
  • In Linux the minicom program can be used

$ minicom -c on

Most likely the device will be /dev/ttyUSB0. Settings:

  • 115200 8N1, no for hardware/software flow control

Refer to the following article for more details on using minicom: Using minicom to connect to Elphel393 camera

Web user interface (camvc)

http://192.168.0.9/

  • The page contains links to camvc user interface for each individual camera port.
  • camvc was ported from the 10353 camera series:
    • change parameters like image format, resolution, auto exposure, auto white balance and more. Alternative way to change parameters is described below.
    • pause compressor and search within buffered images
    • help tips available - see Fig.3 - select then mouse over a control element of interest
Fig.3 enable camvc help tips
Fig.4 camvc controls

Record

  • Recording is done by the camogm program
  • If recording to internal or external SSD, please, read about eSATA port switching
  • important: Event logger (GPS, IMU, IMG, EXT) recording is started/stopped separately. See instructions below.
  • For SATA devices camogm supports:
    • recording to a partition with a file system - up to 80MB/s
    • (default) faster recording to a partition without a file system (raw partition) avoiding OS calls - up to 220MB/s
  • To extract data from a raw partition use dd or these scripts to get the data and split it into images. Follow this link for details.
  • Can record to an mmc partiton or usb.
  • More info
  • If the prefix parameter, which is absolute path + prefix, for a channel is not set the file will be written somewhere to rootfs.
    • if prefix is empty then the absolute path must end with a slash.

browser

Example 1: (provide a correct media mount point - /mnt/sda1/)

Follow this link for GUI description.

command line

Example:

  • /home/root, file prefix=test_, 1GB or 10min files whichever occurs first
    • setup and start (in one line):
echo "format=mov;status=/var/tmp/camogm.status;prefix=/home/root/test_;duration=600;length=1073741824;start" > /var/volatile/camogm_cmd
    • stop recording:
echo "stop" > /var/volatile/camogm_cmd
sync

More information

  • All stored parameters are automatically restored at boot

Available programmable parameters

To inspect all available reprogrammable parameters:

1. http://192.168.0.9 -> Parameter Editor
2. Follow a link for a particular port, e.g. http://192.168.0.9/autocampars.php?sensor_port=0
3. Select groups of interest in the top table -> View/Edit Current

Change parameters

Read:   http://192.168.0.9/parsedit.php?sensor_port=0&PAR1&PAR2
Change: http://192.168.0.9/parsedit.php?sensor_port=0&PAR1&PAR2 - update values - submit form

    • GET request - XML response

Read:   
        http://192.168.0.9/parsedit.php?immediate&sensor_port=0&PAR1&PAR2
Change: 
        http://192.168.0.9/parsedit.php?immediate&sensor_port=0&PAR1=VAL1&PAR2=VAL2
Change for multiple ports at once:
        http://192.168.0.9/parsedit.php?immediate&sensor_port=0&PAR1=VAL1&*PAR1=MASK1&PAR2=VAL2&*PAR2=MASK2

# A port bit mask is set by adding a * to a parameter name, like *PAR1 - it is individual for each parameter.
# The mask is 4 bits - 1 bit per port, bit[0] = port 0,... bit[3] = port 3, where 1 - enabled, 0 - disabled:
#   0xf - the parameter's new value will be applied to all ports.
# More information

Note 1: if the parameter's value is specified in URL it will be applied. The call can have mixed specified and unspecified parameters.

Note 2: The new value is read on the next call.

Example:

  • set 10 fps and enable output trigger signal

http://192.168.0.9/parsedit.php?sensor_port=0&immediate&TRIG_CONDITION=0&TRIG_OUT=0x66555&TRIG_PERIOD=10000000&TRIG=4

More information


Notes:

  • parsedit.php and autocampars.php were ported from 353 camera series. There are a few changes from the originals related to 4x sensor ports:
    • parameters are individual for each sensor port - writing parameters to multiple port at once is controlled with a (bit-)mask input box
    • if opened w/o sensor_port specified the page will show links to available ports
    • sensor_port=x, where x=0..3 - in the address string - for a single sensor camera it is normally 0

Image formats

JPEG

  • color: YCbCr 4:2:0, 3x3 pixels
  • mono6: monochrome - color YCbCr 4:2:0 with zeroed out color components
  • mono : monochrome - color YCbCr 4:0:0 with omitted color components

Note: JPEG is not the best for processing since some information gets lost when demosaicing is applied.

JP4

Proper shutdown

  • if not properly shutdown - in a rare case the μSD card can get corrupted (it's always safer to run sync)

~# sync
~# shutdown -hP now

Same effect:

http://192.168.0.9/autocampars.php?reboot

Development

Usage of SDK, which is Eclipse and project tree cloned from git.elphel.com, simplifies the development. At the same time lots of things can be done using Python, PHP, JavaScript or C/C++ (if compiled on hardware) and do not require SDK.

Other info

Change default ip address

Modify /etc/network/interfaces, sync the changes to the file system and reboot (or rerun init scripts).

For firmware 20180511 or older, follow these instructions to fix network configuration (= disable setting ip address via /etc/elphel393/init_elphel393.py).

Add a program or a shell command to autostart on boot

There's a way to do this using cron or init.d but it might run before the sensors are initialized by init_elphel393.py. The recommended way is the following:

  • nano or vi

ssh root@192.168.0.9
pass
root@elphel393:~# nano /etc/elphel393/init_elphel393.py
edit - save
example: to launch the rtsp streamer - add shout("/usr/bin/str") to the end of the file. shout() function is just a wrapper for subprocess.call(cmd,shell=True)

Then:

#boot from NAND flash?
root@elphel393:~# overlay_sync 1 
root@elphel393:~# shutdown -hP now
#powercycle
#boot from card?
root@elphel393:~# sync
root@elphel393:~# reboot -f

Available lengths for cables for connecting sensors in custom setups

  • FPC cables - click for available lengths.
  • The cables are asymmetrical - for correct connecting a sensor to a system board see the figure below. As a rule of thumb, the cable's back side (no contacts) will be on the same side with the connector's cover.

Known problems

  • [SOLVED] Vertical artifacts in jpegs. Images are ok at 100% quality. Fixed, testing.
  • [SOLVED] http://192.168.0.9:232x/noexif/mimg - multipart jpeg displays corrupted frames from time to time. Reason: network bandwidth?
  • [SOLVED] Sometimes on power-on (NAND flash boot) cannot mount the card's rootfs partition. Kernel Panics. Power off/on. Soft "reboot -f" works ok.

...
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)
...

More info

  • [SOLVED] Changing exposure/quality/gains - can corrupt images - needs testing.
  • [SOLVED] After rewriting rootfs to μSD card - some of the cards get a corrupted partition - re-partitioning (reformatting?) solves the problem.

On the camera the rootfs is mounted as RW and some of the files are changed (also links created) -
most of the changes are now moved to tmpfs but something might have been missed.

Notes

  • [SOLVED] In case rootfs is on flash, it might make sense (or maybe not as the history is updated only once on session exit) to disable bash sessions command history - disable bash history
  • [SOLVED] When using overlays, deleting, existing in the lower layer, dirs can cause errors (hopefully it gets fixed someday), example:
    • /mnt/sda1 exists in lower layer: /tmp/rootfs.ro/tmp
    • upper layer is mounted to "/"

# rmdir /mnt/sda1
# mkdir /mnt/sda1
mkdir: cannot create directory '/mnt/sda1': Operation not supported
