Hello,

I have a strange u-boot command line.I don't know how I get the line "s bootcmd sf=probe 0".

Environment size: 426/16380 bytes

U-Boot > pri

bootdelay=3

baudrate=115200

ethaddr=00:0e:99:02:ff:2b

help=help

filesize=1E85EC

fileaddr=C0700000

ipaddr=172.16.3.100

serverip=172.16.3.203

bootfile=uImage

s bootcmd sf=probe 0 <---here!!

bootargs=console=ttyS2,115200n8 noinitrd rw ip=none root=/dev/mmcblk0p1 rootfsM

stdin=serial

stdout=serial

stderr=serial

ver=U-Boot 1.3.3 (Dec 2 2010 - 23:17:15)

bootcmd=tftp;bootm

Environment size: 426/16380 bytes

I first thought it was the other line of bootfile. So I set the bootfile: "setenv bootfile uImage". But then it became:

Environment size: 426/16380 bytes

U-Boot > pri

bootdelay=3

baudrate=115200

How to delete that command line or reset the whole command script?

Thank you!

Hi,

s bootcmd sf=probe 0 <---here!!

Nothing strange about what you have done is accidentally done ' set s bootcmd sf=probe 0 '

on the U-Boot command line prompt, because of which you are seeing it.

How to delete that command line or reset the whole command script?

you can do it by erasing the U-Boot and refalshing it.

Try to set this variable is empty:

setenv s; saveenv;

may be it is help for you.

Hi,

setenv s; saveenv;

Doing this will still list 's' when you do printenv.

Hi, Prabhakar Lad!

In this case you don't need rewrite u-boot image, you can erase only environment variables and set variables again (RAM addresses may defer for your board):

sf probe 0

mw.b 0x81000000 0xff <env section size in spi>

sf write 0x81000000 <env section start addr in spi> <env section size in spi>

reset

saveenv
