The 0x20 offset is a convenience for the app binary image generation.
|
|
Flash cache has 64KB pages. The .bin file which is flashed to the chip
|
|
has a 0x18 byte file header, and each segment has a 0x08 byte segment
|
|
header. Setting this offset makes it simple to meet the flash cache MMU's
|
|
constraint that (paddr % 64KB == vaddr % 64KB).)
