I am trying to run the aditof-demo for ad96tof1 sensor and I am getting the permission denied error for fopen() function in eeprom.cpp


 


See the following log.

This is happening in every demo example.


 



and i observed that the eeprom mentioned in 53-aditofsdkjetson.rules does not exist in /sys/bus/i2c/devices/6-0056/. also it shows 6-0064 in above log so should we change that here in the 53-aditofsdkjetson.rules file?




please help se the proper permissions needed to run the demo.


 


thanks.

    Hi,
    

    Does it work if you run the demo with 'sudo'? Or that doesn't help either?

    I was running it with "sudo'' only.
    

    I used i2cdetect for checking the connection and had to change the port. And after restart it worked for me. 
    

    In current SD card image I am unable to use the internet using usb tethering and also I am unable to use the wifi adaptor also.
    

    I had also installed the appropriate drivers and this drives works with another jetson image.
    

    There was also issue with building the driver since there are no built modules in the /lib/modules/4.9.140-tegra.
    

    How can I resolve that?
    

    

    Alternatively, I'm trying to build the new kernel with instructions from  wiki.analog.com/.../ug_jetson on latest jetson nano image[new image taken from https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit#write] for tof sensor to work.
    

    I did all the steps but after rebooting it seems like jetson did not boot up.
    

    I connected jetson to pc using PUYTTY and I was getting log there.
    

    Afterwords I was able tousethhe monitor via HDMI cable. Is there any specific option in kernel configuration that is responsible for dp port failure?
