NAND Flash

The NAND FLASH is attached to the FCM on local bus and works at 8-bit mode.

The NAND FLASH is Micron MT29F8G08ADADAH4 whose FLASH size is 08 G bits or 1 G Bytes.
The pages are large and each page contains 2112 bytes including 2048 bytes of data and 64
bytes of spare. There are totally 8192 blocks, each block contains 64 pages including 128 KB of
data and 4 KB of spare.

The NAND FLASH is only used as NAND FLASH JFFS2 rootfs.The detailed map is described in the
following table:

HSSI OR SERDES Block

SCP-P4040-4G-ENP2 contains SERDES 3 banks including a total of 18 lanes. From the 18 lanes
of SERDES, 12 are routed to the COM Express connectors, defined as SERDES0~ SERDES7
(SERDES0~7 of bank 1) and SERDES16~SERDES19 (SERDES10~13 of bank 2).
SERDES8~SERDES9 of bank 1 are used for Aurora debugger defined as Aurora0~1.
The remaining 4 lanes of bank 3 are not used in P4040.

The protocol running at each lane or each group of lanes routed to COM Express connectors are
configured by the RCW, available options are shown in the following table:
