New page

As it was mentioned in [[Camogmgui | camogmgui]], ''camogm'' can save images to a raw partition or disk in fast recording mode and you need to do one additional step to extract these images from such a partition. This short note describes how to get images from raw partition.

1. Download [[https://github.com/Elphel/elphel-tools-x393 these scripts]] to your PC.

2. Connect camera to eSATA port, power it on and wait until it has loaded.

3. Copy ssh key to camera. This step can be skipped if it was done before.
$ ssh-copy-id root@192.168.0.9

4. Run ''int_ssd_download.py'' script to dump camera's raw partition to PC.
$ ./int_ssd_download.py -c root@192.168.0.9 -n 1 -bs 100 -bc 1 .
root@192.168.0.9: connection ok
root@192.168.0.9: raw partition name: Crucial_CT250MX200SSD6_1531103B6ABA-part2
umounting /dev/sda1
root@192.168.0.9: Enabled connection: internal SSD <-> PC
Connect camera (eSATA) to PC (eSATA/SATA). Press Enter to continue...
[sudo] password for mk:
Getting raw partition data from /dev/sdb2
1+0 records in
1+0 records out
104857600 bytes (105 MB, 100 MiB) copied, 0.501566 s, 209 MB/s
Waiting for disks to show up:
[]
root@192.168.0.9: Enabled connection: internal SSD <-> Camera
Done
Here, the ''-c'' parameter specifies which camera to use and script controls this camera to switch internal disk to eSATA and find raw partition. The ''-n'', ''-bs'' and ''-bc'' parameters specify the number of chunks to download, block size in MB and the number of blocks in each chunk respectively. The script will create a subdirectory, which name is made of disk manufacturer, model and partition number, and download disk dump into this subdirectory.

Normal recording assumes there is at least one partition with a file system. Follow [[HDD_Format | this guide]] from step 1 to step 4 to prepare a partition for normal recording if your disk is not partitioned yet. Fast recording mode requires at least one partition without file system. Follow [[HDD_Format | this guide]] from step 1 to step 3 to prepare such partition. As alternative, the whole disk can be used as a fast recording buffer and no actions with disk required in this case given that the disk in not partitioned. -To do so follow [[HDD_Format | this guide]] from Steps 1 - 4.+==Interface==  +===Main window===  +Open the following link in your browser to start ''camogmgui''  + http://192.168.0.9/camogmgui.php  +[[File:Camogmgui main.png|center|alt=Main window]]  +The main window of the program consists of several areas (marked in red on the image) and two of them, preview (1) and buffers usage (2), are folded by default. The third area displays a list of files recorded in normal mode to some directory on the mounted disk. This list is empty right after start and you need to press ''Reload'' button to refresh the list. ''Create folder'' button makes new subdirectory in the current directory and ''Set Target Folder'' sets selected directory as a location for recorded files. The group of tabs on the right side contains status information and controls for recording. The first tab of the group, ''Status'', shows status of all ports and some recording statistics. Some fields on this tab are empty right after start but they will be updated as soon as recording has started.

The camera equipped with a drive should be configured in a way that the drive can be accessible from Linux operating system. This is normally done with a configuration script which is executed during system boot. The script is located in the /etc/elphel393 directory and called ''init_elphel393.py''. There is a set of parameters which this script receives from init script /etc/ini.d/init_elphel393 and one of them is responsible for SATA controller configuration and driver loading: -  SATA_EN=1+  \"sata\"            :1, Make sure this parameter is set to 1 if your camera is equipped with SSD drive.
