Contents
Defaults
IP addr: 192.168.0.8 user / pwd: root / <empty>
- The address is set by the init_elphel393.sh script on the card's FAT32 partition.
Boot
- on power-on boots from NAND flash: u-boot, device tree and kernel.
devicetree has "chosen = ...root=/dev/mmcblk0p2..." - rootfs is on the micro SD card second partition.
Command line access
ssh root@192.168.0.8
Serial console access
- Use microUSB-USB cable to connect to PC - the cable's end should be thin enough otherwise interferes with the micro SD card.
- Terminal: minicom -c on
(setup the device and speed - default settings might just work)
Get images

channel 2: http://192.168.0.8:2324/noexif/img

channel 4: http://192.168.0.8:2326/noexif/img
Change parameters
- http://192.168.0.8/controls.html - previews and basic parameters:
- Exposure - the values are in the sensor lines.
- WB - r,g,b gains
- Quality - compression quality - individual for compressor but common for the buffer driver - it's better to have the same value for all channels.
- The defaults settings are define on the micro SD card, FAT32 partition - local/verilog/startup:
... -c write_sensor_i2c all 1 0 0x9009001e (exposure) -c write_sensor_i2c all 1 0 0x9035000a (set all gains to 0xa) -c write_sensor_i2c all 1 0 0x902c000e (blue gain to 0xe) -c write_sensor_i2c all 1 0 0x9009001d (red gain to 0xd) ...
Known problems
- Vertical artifacts in jpegs. Images are ok at 100% quality. Fixed, testing.
- http://192.168.0.8:232x/noexif/mimg - multipart jpeg displays corrupted frames from time to time. Network bandwidth.
- Sometimes on power-on (NAND flash boot) cannot mount the card's rootfs partition. Kernel Panics. Power off/on. Soft "reboot -f" works ok.
- Changing exposure/quality/gains - can corrupt images - needs testing.
