[U-Boot-Users] autoscr can't execute script in u-boot 1.2.0

[U-Boot-Users] autoscr can't execute script in u-boot 1.2.0

[frisky_linux]

Hi all,
I have tested the autoscr command and found that autoscr can't execute script in u-boot 1.2.0. 
The steps follow here:
1. Generate autos.img
	1) echo "printenv serverip" >>test.txt
	2) mkimage
[frisky at FC6 test]$ mkimage -A ppc -O linux -T script -C none -a 0 -e 0  -n "auto script example"  -d test.txt autos.img && rm -rf /tftpboot/coreblade/autos.img &&  cp autos.img /tftpboot/coreblade/ 
Image Name:   auto script example

Entry Point:  0x00000000
Contents:
   Image 0:       19 Bytes =    0 kB = 0 MB

2. In u-boot command shell, download autos.img,check it and run.
	1) tftp 200000 coreblade/autos.img
coreblade => tftp 200000 coreblade/autos.img

	2) Check this image

	3) Run it!!
coreblade => autoscr 200000
## Executing script at 00200000
" not definedrverip

	4) But I can see the serverip defined.
coreblade => printe serverip
serverip=10.3.8.66 

I don't know what's the problem.  Could you please help me? Thank you very much!

Note that you *append* to "test.txt" here, so you probably already
have garbage in that file... ?

This looks wrong to me.

If you execute the commands above with an empty/nonexisting file
"test.txt", the result should be:

-> ls -l test.txt
-rw-rw-r-- 1 wd wd 18 Sep 26 08:44 test.txt

i.e. the file should be 18 bytes, not 19 as in your case.

It seems you already had one byte of garbage in "test.txt"

This works fine for me:

[frisky_linux]

Yes! You are right!
My test.txt has one '0x0D' at the end of the line:( It should be '0x0A',not '0x0D 0x0A'.
I have copied a DOS text file.
Thank you!
