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.... |
