| 我的板是256M nand flash,东华3.5寸屏 
 我把nand flash格式化了:
 nor启动,u-boot命令9 Format the NAND Flash
 ##### Erase Nand Menu #####
 [1] Nand scrub - really clean NAND erasing bad blocks (UNSAFE)
 [2] Nand earse - clean NAND eraseing
 [q] Return main Menu
 Enter your selection: 2
 Start address: 0
 Size(eg. 4000000, 0x4000000, 64m and so on): 256m
 最后显示100%Complete ,OK
 
 之后从nor启动进u-boot,不论往nand flash烧写什么(logo,u-boot,linux,yaffs),从nand flash启动都是白屏!!!
 而且在烧写logo,u-boot,linux之后若直接选命令8 Boot the system就有如下显示:
 Enter your selection: 8
 Start Linux ...
 Copy linux kernel from 0x00200000 to 0x30008000, size = 0x00200000 ... Copy Kern
 el to SDRAM done,Warning: this binary is not compressed linux kernel image
 zImage magic = 0x00000000
 NOW, Booting Linux......
 然后卡死,一直不动!!!
 
 我试过用H-Jtag烧写nand flash u-boot,可从nand flash启动还是白屏!!!
 我怕是u-boot与linux版本不配,换了几套烧写镜像都不行....
