Hi xuhui

seems it could be used in similar way only use /dev/mtdX

instead /dev/mmcblk, please check description of linux nor usage in

http://datasheets.bluetechnix.at/goto/dev-i.mx31/dev-i.mx31_softwareusermanual_v2.pdf 

also please check sect.4.6 Flash memory maps attached Linux Guide

Best regards
igor
