jevois-inventor does not work with new lens

+2 votes
I just bought this product (https://www.jevoisinc.com/products/copy-of-jevois-0-3mp-low-light-sensor-with-standard-90deg-120deg-and-noir-lenses) and tried to change the sensor with the new one. I was surprised that with this new sensor jevois-inventor does not launch as expected. I can not use the cam with the new sensor !

 I then took the original sensor and changed the lens by cutting the glue spot. It worked but i still don't understand why the sensor i bought seems uncompatible with jevois cam and especially with jevois-inventor.

Can you clear it up for me ? Is the product i bought malfunctioning ?

Oh, the optional sensor you got is a different model than the original, Omnivision ov7725 instead of originally an ov9650. To use it, you need to configure the JeVois software as explained here:


Basically, you just need to write a file called "sensor" in the boot partition of the microSD and in there write a single word: ov7725

Then the camera will attempt to detect and use that sensor when it starts up.

thx for the explanations . Unfortunately I tried to install the ov2640 sensor here and I did what you explained ( I created a 'sensor' file with     "ov2640" written inside ) and then I put back the SD card in the cam and restarted the cam and Inventor but I get a black screen .  Can you help me fixing this black screen please ?
