1. Defaults: IP addr: 192.168.0.8 user / pwd: root / <empty>

2. on power-on boots from NAND flash: u-boot, device tree and kernel. devicetree has "chosen = ...root=/dev/mmcblk0p2..." - looks for rootfs on the micro SD card 3. ssh root@192.168.0.8

4. Use microUSB-USB cable to connect to PC: terminal: minicom -c on (setup the device and speed - default settings might just work)

5. channel 1: http://192.168.0.8:2323/noexif/img channel 2: http://192.168.0.8:2324/noexif/img channel 3: http://192.168.0.8:2325/noexif/img channel 4: http://192.168.0.8:2326/noexif/img

6. 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. 7. Known problems: Vertical artifacts in jpegs. Images are ok at 100% quality. http://192.168.0.8:232x/noexif/mimg - multipart jpeg displays corrupted frames from time to time. 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.
