NAND FLASH
The NAND FLASH is a Micron MT29F8G08ADADAH4 with a size of 8Gb/1GB. Each page
contains 2112 bytes including 2048 bytes of data and 64 bytes of spare. Each block contains
64 pages including 128KB of data and 4KB of spare. There are a total of 8192 blocks.
As shipped, the NAND FLASH is only used as NAND FLASH JFFS2 rootfs. The map is described as
below table:

SERDES Block
The P4040/P4080 CPU provides 3 banks of SERDES with a total of 18 lanes. Bank 1 routes 8
lanes to the COM Express connector as SERDES[0:7]. Bank 2 routes 4 lanes to the COM Express
connector as SERDES[16:19]. Bank 3 also routes 4 lanes to the COM Express connector but is
unused for this module. Bank 1 provides 2 additional SERDES lanes on-board for CPU
debugging through the Aurora interface. See note in the
