Thank you for contacting Intel Embedded Community.
In order to be on the same page, could you please let us know why you need this information?
Waiting for your clarification.
I have a requirement which needs lesser memory size (store some time drift information).
Hence I have posted this question.
Thanks for your reply.
512KB is the smallest size to fit the smallest NVM image. Due to this fact, a 128KB flash memory is insufficient to have the Dev starter NVM image.
We hope that this information may clarify your question.
