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.

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?

I am using a Direct USB cable

I checked the dmseg messages, I see this one appear when I try to run the application

[ 6366.713132] uvcvideo: Failed to query (GET_CUR) UVC control 5 on unit 3: -110 (exp. 60).

Is it an issue with linux ?, I am on ubuntu 20.04 LTS

110 is the error code for timeout. Can you try to reboot both the board and your PC?

Also, is you aditof_sdk on the PC up-to-date? (latest from master)?

Yes I have updated and rebuilt the applications, the timeout issue has gone after reboot, but I see this,

I haven't seen this before. If you start the demo 2-3 times, will the same error be displayed? (I'm trying to figure out if USB communication is unstable or it's something else this time)

Yes, its consistently the same message, I tried to run the first-frame application,

Any idea what this could mean "Could not find 24c1024 while looking for storage for camera AD-96TOF1-EBZ" ?

Yes, the 24c1024 is the name of the driver for the EEPROM of the AD-96TOF1-EBZ. It should be found on Dragonboard at path: /sys/bus/i2c/devices/0-0056.

There's another application, called uvc-gadget that is reponsible for the USB communication between the AD-96TOF1-EBZ and a PC. The uvc-gadget should send the name "24c1024" to the PC in order to let it know that the EEPROM with this name is available.

Can you run the demo directly on board? Does it work?
