太过奖了!!当然,为了移植,我是看了一部分代码,但是没有全部看,因为和移植相关的就那么几处,而且还有高人前辈已经做好了的.我也就是玩一下而已,以前在学校做Xsale PXA255,那才爽.我一个同学毕业设计就是搞bootloader,当时u-boot其实已经有人移植到我们那个Sitsang板子上了.目前,u-boot for lumit4510 已经可以做到如下一些事情:
1.将uClinux kernerl image 烧写到flash中,并自动运行.通过网络的tftp,这个和版主limingth老大的tftp1.6.0正好相反,u-boot在主机上用的是tftp-server,u-boot自己有tftp-client来支持.当然,u-boot还有好几种其他的网络启动方式,例如bootp,nfs等,应该都已经能用.
2.不好一一说了,我用help看了下,下面的命令基本上都可以用.不过我还没有时间去一一试用.(我甚至还用u-boot自己把自己更新了一次.)
? - alias for 'help'
autoscr - run script from memory
base - print or set address offset
bdinfo - print Board Info structure
boot - boot default, i.e., run 'bootcmd'
bootd - boot default, i.e., run 'bootcmd'
bootm - boot application image from memory
bootp - boot image via network using BootP/TFTP protocol
cmp - memory compare
coninfo - print console devices and information
cp - memory copy
crc32 - checksum calculation
echo - echo args to console
erase - erase FLASH memory
flinfo - print FLASH memory information
go - start application at address 'addr'
help - print online help
iminfo - print header information for application image
imls - list all images found in flash
itest - return true/false on integer compare
loadb - load binary file over serial line (kermit mode)
loads - load S-Record file over serial line
loop - infinite loop on address range
md - memory display
mm - memory modify (auto-incrementing)
mtest - simple RAM test
mw - memory write (fill)
nfs - boot image via network using NFS protocol
nm - memory modify (constant address)
ping - send ICMP ECHO_REQUEST to network host
printenv- print environment variables
protect - enable or disable FLASH write protection
rarpboot- boot image via network using RARP/TFTP protocol
reset - Perform RESET of the CPU
run - run commands in an environment variable
saveenv - save environment variables to persistent storage
setenv - set environment variables
sleep - delay execution for some time
tftpboot- boot image via network using TFTP protocol

我有机会把我用的命令的整个过程保存下来,贴到论坛上,大家原意的话,就尝试一番吧.有些什么问题,大家一起讨论吧!只要大家不要觉得我在浪费论坛的版面!!!
