i210 iNVM limit

[yousuke]

Is there a limit to the number of times the i210 can be written to iNVM?

Hello @yousuke,

Thank you for contacting Intel Embedded Community.

Yes, there is a limited number. You can check section 3.4 from the i210 datasheet.

"iNVM is similar to One Time Programmable (OTP) memory except that it allows for a limited number of modifications and corrections after initial programming."

Best regards,

Is there a way to blank/erase the iNVM to start from square one?
