No i2c device at address 0x40 jetson nano

The way I2C works when you add a second device no changes should be required in your configuration. If the working address stops working it is usually either because of multiple devices with the same address or it is due to an electrical problem. ACK) after the address. If not no device is recognising the address.

Ok, that is strange. Let's do a sanity check here. Run the I2C scanner WITHOUT plugging the camera in. Obviously, the camera can't be found but in order to find the Problem we Need to divide and conquer. If the voltage acts as expected WITHOUT the camera plugged in, then the Problem is something at the camera end. Hi, recently I bought a jetson nano and an imx477. I wanna to deploy imx477 on jetson nano. Here are my steps Download the sd card image from Nvidia website and burn it into a sd card, put the sd card in jetson nano. Here is the version info of the jetpack and kernel I tested this image with IMX219. It works pretty well. Jetson development board has I2C interface. This paper introduces the use of this interface. Pass< Jetson TX1-TX2 Developer Kit Carrier Board Specification > It can be seen that the 3rd and 5th pins in the J21 row of pins of TX2 represent SDA and SCL interfaces respectively, which can be connected. Jun 23, 2014 sudo nano etcmodules. and add these two lines to the end of the file i2c-bcm2708 i2c-dev. now you can manually load these modules with the commands. sudo modprobe i2c-bcm2708 sudo modprobe i2c-dev. now type again sudo i2cdetect -y 0 if you have a rev1 board sudo i2cdetect -y 1 if you have a rev2 board.. Now remember this address and go to the example sketch from library. To test your OLED display and wiring, use the example sketch from the SSD1306 library. The sketch name is ssd1306128x64i2c. Search the sketch and find this part. SSD1306SWITCHCAPVCC generate display voltage from 3.3V internally..
