failed to read firmware from eeprom

Can you try to read the contents of the eeprom using the eeprom tool?

Firstly, make sure you build the tool by using the flag '-DWITH_TOOLS=1'. Ex: ''cmake -DDRAGONBOARD=1 -DWITH_TOOLS=1 ..'

After building the project run the tool like this:

./eeprom-tool -m -r backup.bin

If this runs ok please attach the bin here, else post here the output / error

Thanks for the suggestion.

I did run it and it worked after adding sudo to the command, I see the below  messages,

Attaching the bin file.

, I see the bin file is not getting uploaded here, sent you the bin file on email. Please check

I wasn't able to recover the EEPROM content.

An option is to rewrite the EEPROM with another image.

First thing to do is to update aditof_sdk to latest from master branch. Then use the eeprom-tool to rewrite the EEPROM. You can use the EEPROM content from this file: https://github.com/analogdevicesinc/aditof_sdk/blob/master/misc/ad-96tof1-ebz/ad96tof1_eeprom.bin

Also, what revision is the camera board?

Hi Dan,

On the camera board its mentioned REV D Z, attaching a snaphshot of the module

Thanks, I will rewrite the EEPROM to see if the issue goes away.

Could you confirm, the eeprom tool usage to write to eeprom from a file?

./eeprom-tool -m -w <path to file>  will do?

Hi,

That command will do.

Please let us know the results.

Thanks for the help, Iam able to run aditof-demo now on the dragonboard after writing the new bin file to eeprom. The firmware error does not appear now.

Hi DNechita,

I still cant get the aditof-demo running on my linux pc, below are the messages I seem, any leads on what could be the issue here?

The USB communication seems unstable. Are you using a direct USB cable between PC and Dragonboard? or is there an USB hub in-between?
