The 28F320B3 is a BOOT BLOCK flash part. It contains Eight 8K regions and 63 64K regions. The CFI code assumes that all regions are of the same size. I am currently using this part in a design. To get around this problem, I changed the CFI code to treat the 8K regions as a single 64K region. -Mike ----- Original Message ----- From: "Nick Ivanter" To: "Peter De Schrijver" Cc: Sent: Friday, November 17, 2000 3:44 AM Subject: Re: MTD on intel 28F320B3 flash memory > Are you sure it's not CFI complaint? > I've been working with 28F640 which is CFI complaint and > is detected and operated by the existing code fairly well. > I believe the only difference between 28F640 and 28F320 is > that the latter is smaller.
