老大,把你总结的u-boot 命令的一些用法说明传一份。按照你说我重新编译并烧写
U-Boot 1.1.3 (Oct 2 2005 - 16:12:09)
U-Boot code: 007D0000 -> 007E83E0 BSS: -> 007F2634
IRQ Stack: 007aef7c
FIQ Stack: 007adf7c
RAM Configuration:
Bank #0: 00000000 16 MB
Flash: 4 MB
*** Warning - bad CRC, using default environment
In: serial
Out: serial
Err: serial
Hit any key to stop autoboot: 0
lumit4510 # help
? - 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
version - print monitor version
lumit4510 # printenv
bootargs=console=ttyS0,19200 initrd=0x100a0040,530K root=/dev/ram0 keepinitrd
bootcmd=tftp 100000 uImage.bin
bootdelay=7
baudrate=19200
ethaddr=00:40:95:36:35:33
ipaddr=192.168.1.5
serverip=192.168.1.2
netmask=255.255.255.0
stdin=serial
stdout=serial
stderr=serial
Environment size: 265/4092 bytes
lumit4510 #
只会用简单的几个命令(reset,help,printenv)。
我想把这个u-boot改造成这样:
1。标准输入输出改成telnet,只要PC机通过telnet登陆4510,就出现和串口一样的引导信息。既然他支持网络就利用它远程服务。
2。支持ftp服务,通过通用ftp终端软件上传下载程序,并在telnet里输入命令运行他。
我也断断续续看了一些别人写u-boot移植说明,但是还有很多疑问想跟老大请教。方便的话能留个QQ号吗?群里好像做u-boot移植的很少。先谢了!:):) |
