[Elphel-support] An error in replacing the 14-megapixel sensor(mt9f002) by 5-megapixel sensor(mt9006)

[Elphel Support]

Hello Ali,



There should be no problems with impedance matching, we tested both types of sensors with up to 450mm cables (for ectremely long cable programmatic phase adjustment may be needed). And the cables are the same for both serial (14MPix) and parallel (5MPix).

Hello Oleg

yes, i can 'ssh' to camera and also can send  the/var/log/autocampars.log. The microSD card marked "5MPx" is also insert to the slot.

We opened the camera. When closing the sensor cable was pressed  slightly and deformed. I guess the cable is damaged. In the parts list of the "5 MPx" sensor, FFC cable with model number 050-30-51B, is provided. But by connecting this cable, the sensor is not detected eaither.The connection photo is sent in the attachment. Could there be a problem with the cable (for example, impedance matching, etc.)?

~$ ssh http://mailto:root@192.168.0.9
~# cat /var/log/autocampars.log


Or if you use minicom - send the boot log.



If I remember right you should have a microSD card marked a "5MPx" - the camera autoboots from the card - I suggest you try the card first. And the only thing you will need is to set "MT9P006" from the bootblock393 page.



Regards,

Oleg

Hello
We have provided your product 10393. Your camera is very well designed and made. Thank you for your good products and complete documentation and your support.

Sensor installed on 10393 is a 14-megapixel sensor (10398) "mt9f002" by default that Works well. We also bought the 10338 "mt9006" sensor. By replacing the sensors, the new one is not detectable and no image is seen.

We downloaded the latest firmware, although the default sensor is "mt9006"  in the manual, the "devicetree.dtb" replacement process was performed according to the instructions,10393 nand flash was programmed but the sensor is not detected again.The image of error in web interface sent in the attachment. Thanks for your support in solving the problem.
