If I have a NAND chip, say
https://www.winbond.com/hq/product/code-storage-flash-memory/serial-nor-flash/?__locale=en&partNo=W25Q128JV and its supposed to have say 128 mb or 64 mb of storage or whatever, how the the REVELPROG-IS know to only copy 8mb or less from the chip? I only ask because I keep getting incomplete binary images. Does it go until it sees a bunch of NULLs?
