It seems to be possible to run the i210 with default nvm – device id 1531. Has anyone done that already?
Sorry, but you got your nomenclature completely wrong. This is no default NVM but rather an un-programmed NVM which Intel calls in their data sheet “tools only, not for driver” which is clearly illegal for any kind of regular use.
Are there good reasons to not let it run in default mode?
Tools only mode is tools only mode, nothing more and nothing less. We only run it in this mode during early production testing before actually properly programming the NVM patches for which you may find here and here.
Please contact your Intel FAE for any details about such proprietary Intel chips and their behaviour in an unsupported scenario.
If the device is running in default mode
Tools only mode that is.
does anybody know if it has a default MAC ID assigned from intel or is this blank as well.
Of course, if the NVM is not programmed there is no MAC address. So this is really more a driver question. The regular driver will anyway not load should the NVM checksum not be proper.
If not running in default mode, has anybody already successfully used the intel EEUpdate tool from the imx6 board?
I never heard of such EEUpdate tool resp. I was under the impression that this is an X86 only tool and on ARM one would need to use what is called eepromARMTool which is exactly what we do in our Apalis T30/TK1 production.
BTW: Rather than hijacking an old question please ask a new question next time properly specifying what exact hardware (module and carrier board) and software versions of things you are talking about. Thank you!
