Hello,

I have a problem with Jetson Nano SD card image for AD-96TOF1-EBZ, can you help me please?

Looking at the output of the ADDI9036 driver, it looks like there is a problem with the I2C communication.

This might be because you are using a different version of Jetson. The one we used is Jetson Nano…

Sorry for the delayed reply, we are currently working on fixing the issue.

In the meanwhile an option would be to use the code from release 1.5.0, which should work fine on the Jetson Nano: https://github…

Hi,

It looks like websockets was linked to a version of openSSL. And in the meantime, the operating system was updated with a newer version of openSSL which doesn't have the functions that appear in your build log.

You need to rebuild websockets. Check the steps at (see Libwebsockets section):

https://github.com/analogdevicesinc/aditof_sdk/blob/master/doc/linux/build_instructions.md

And then rebuild the aditof_sdk.

Or, if you don't care about the network component (you just want to run things on the Jetson Nano) you can disable this component and you won't need websockets nor protobuf dependecies. You can disabled it from cmake:

cmake -DJETSON=1 -DCMAKE_PREFIX_PATH="/opt/glog;/opt/protobuf;/opt/websockets" -DWITH_NETWORK=OFF ..

Hi,

Thanks for your advice.

After rebuilding websockes, I confirmed that aditof-sdk could be built successfully, either 1.6.0 or 1.5.0.

Unfortunately, when I ran imshow_jetson, I got following error messages.

Looks like extra permission is needed to access the EEPROM (Error eeprom_open: Permission denied)

Can you please try to run the example with sudo?

Looking at the output of the ADDI9036 driver, it looks like there is a problem with the I2C communication.

This might be because you are using a different version of Jetson. The one we used is Jetson Nano 2GB Developer Kit.

So you will have to do some modifications to the device tree in order to map the I2C for the new board. My understanding is that your version of the board has an additionally I2C MUX and because of it, the device tree needs to be changed.

Hi DHechita,

Thanks for your answer.

I understood that I need to modify the device tree for my Jetson Nano 4GB.

Could you please kindly let me know how to do it ?

Hi,
Firstly I would suggest to try to flip the flex-cable and also try to plug it in the other port.
Secondly, it would be a good start to use i2cdetect in order to find the i2c bus that the camera connects to:
In a terminal type:
i2cdetect -l

in order to list all i2c buses.
Then list the devices on each bus until something appears at 0x64 (the camera), 0x56 (the eeprom) and 0x49 and 0x4b (temperature sensors).
For example, in order to list the devices on bus 2 type:

i2cdetect -r -y 2

After you find the correct bus, please post the result.

Hi Litan,

Thanks for your replies.

I got the same result from 4 cases shown below even I tried to flip the flex-cable and also try to plug it in the other port.

case 1 ; do not flip the flex-cable and plug original port

case 2; flip the flex-cable and plug in the original port

case 3; do not flip the flex-cable and plug in the other port

case 4; flip the flex-cable and plug in the other port

analog@analog-desktop:~$ i2cdetect -l

Hi,

As far as I can tell from those results the camera is not detected on any i2c bus (although something is present at 0x64 on bus 6, the EEPROM should also be present to be sure that is the camera).

I suggest that you do some more tries until the camera is detected on one of the i2c buses:

When flipping the cable make sure to do it on both ends, for example: make sure that the blue plastic is oriented in the same direction on both connectors.

Try another cable

Try to turn on the camera before booting the board

Sample output from i2cdetect with the camera connected properly:
analog@analog-desktop:~$ i2cdetect -r -y 9 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- UU -- -- -- 40: -- -- -- -- -- -- -- -- -- 49 -- 4b -- -- -- -- 50: -- -- -- -- -- -- 56 57 -- -- -- -- -- -- -- -- 60: -- -- -- -- UU -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- --

How the camera was connected:

(notice the blue plastic)

Also run:

lsmod

in order to see if the driver is loaded.

Hi Virgil,

Thanks for your help.

I can find host i2c devices as below.

I also tried running imshow-jetson and confirmed that it worked properly.
