How do I determine FPGA image size within a POF

ted, I had indeed found that pdf file last week during my searching. It has been quite insightful. The only real confusion coming out of that document is the bytes 4-7 (as indicated in the preceding post) and the packet type 0x11 doesn't appear to be described.

dsl,

Thanks for the info. That pretty much lines up with what I was assuming (so I appreciate the confirmation).

Here is what is still confusing me. The footer has the mPage_0 with the offset into the packet 0x11 flash space which tells me where the FPGA image actually starts, but the second hex number doesn't appear to be the size of the image. In my case if I start at the offset provided (0x00020000 which ends up being 0x20094 in my file due to header) and search forward until I start getting all 0xfff, I get to address 0x0387f60. This gives me a size of 0x0367ecc. However the second hex number in my footer is 0x01b3f830. Any ideas on why these numbers don't match, or what the 1b3f830 is really telling me?
