COMX-P2020 Module Installation and Use (6806800K97F)

4.3

Memory

The U-boot will configure the memory controller with the fixed parameter instead of SPD

information on the SOUDIMM.

4.3.1

SDRAM

COMX-P2020 only supports 2 GB DDR3 667MT/s DDR3+ECC arranged in two ranks in
one slot.

4.3.2

SD Card

COMX-P2020 has a microSD card slot on-module with a 2GB SD card installed. The SD
card stores the Bootloader and the Operating System.

The eSDHC acts as a bridge, passing host bus transactions to SD/MMC cards by sending

commands and performing data accesses to or from the cards. It handles the SD/MMC
protocol at the transmission level.

4.3.3

SPI Flash

COMX-P2020 has an SPI socket on-module with a 4MB SPI Flash installed. The U-Boot is
installed in the SPI flash on module.

The flash was divided into three areas: configure data, U-boot, and Environment argument

area.
