sannce_i141cb_v2.bin + bg0806 + kernel Linux version 3.10.14 (eko@eko-GE62VR-6RF) (gcc version 4.7.2 (Ingenic r2.3.3 2016.12) )

[markonym]

Hi I want to ask questions about an old problem that is already closed. I have sannce clone

and I did reflashing uboot sannce_i141cb_v2.bin, put in ext3 sdcard rootfs as described in sannce.md.

dmesg.txt

rcS.txt

v4l2rtspserver-master.txt

v4l2rtspserver-master.txt sensor datasheet --> http://www.brigates.com/product/3.html bg0806应用指南_v2.0.pdf

I can boot and reach camera site but I can't see any picture and can't move PT. I saw in original rootfs that it use different image sensor BG0806. I used kernel-t20.bin on uEnv.txt. on rcS I used mt7601Usta.ko , disable dafang sensor and added sensor_bg0806.ko and module bg0806.bin that I extracted from original flash dump.

Whatever I tried, there is no video ... how can I do it?

Hey @markonym,

What voltage did you use to gather serial data? Do mind sharing a picture of the board? I have a Sannce camera that I want to dump the info also.

[markonym]

Hello colleague, my camera is a Chinese clone of Sannce with a cpu Ingenic T20. For serial communication use 3.3 volts.

Hey! Thanks for the reply. I have a camera called Ankee but looks similar to the Sannce one. and wanted to know the normal voltage used for serial communication on the CPU.

[markonym]

Make it look the same as my camer a!

[yeyeto2788]

Awesome! Thank you very much @markonym .Did your camera finally worked?

@EliasKotlyar is there anything to be done in regards making it work?

[markonym]

Before you start doing various experiments with the camera, be sure to make a dump on the flash !!!

[markonym]

To work as a device but no picture from the sensor

[yeyeto2788]

@markonym I'll keep it in mind. The weird part is that using 115200 baud rate I do not get any console output

[markonym]

What usb to uart converter are you using?

[yeyeto2788]

FTDI USB to serial converter

[markonym]

Wonderful!

[yeyeto2788]

Seems like I'm now able to log into the camera as root and do some things on it. @markonym did you get it work with the hacks? Is there an option to open up this issue again? My camera is based on a T10 but I guess most of the hacks should work.

@EliasKotlyar any way I can help on this?

[markonym]

Yes Elias hacks work for me. Download and flash this bootloader - sannce_i21ag_v2.bin ( for Ingenic T10).

[markonym]

Which who terminal program are you working ? I use Tera Term !

[yeyeto2788]

Yes Elias hacks work for me. Download and flash this bootloader - sannce_i21ag_v2.bin ( for Ingenic T10).

I thought your camera was a T20 one. Ok I'll try that then.

I'm using picocom and now I can get full access to the terminal via serial or telnet.

[markonym]

Yes my camera is with T20. But your bootloader is sannce_i21ag_v2.bin mine is different.

[markonym]

Do you see U-Boot already ?

[yeyeto2788]

Yes I was able to see u-boot and even set some bootargs. I'll try that firmware after I dump everything from the camera as a safety measure.
