failed to read firmware from eeprom

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?

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)
