[U-Boot-Users] autoscr can't execute script in u-boot 1.2.0
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@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 Created: Wed Sep 26 10:17:46 2007 Image Type: PowerPC Linux Script (uncompressed) Data Size: 27 Bytes = 0.03 kB = 0.00 MB Load Address: 0x00000000 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 Waiting for PHY auto negotiation to complete.. done ENET Speed is 100 Mbps - FULL duplex connection (EMAC1) Using ppc_4xx_eth1 device TFTP from server 10.3.8.66; our IP address is 10.4.40.1; sending through gateway 10.4.0.254 Filename 'coreblade/autos.img'. Load address: 0x200000 Loading: # done Bytes transferred = 91 (5b hex)
2) Check this image coreblade => iminfo 200000
## Checking Image at 00200000 ... Image Name: auto script example Image Type: PowerPC Linux Script (uncompressed) Data Size: 27 Bytes = 0 kB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK
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!

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"

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!

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.
But that would not cuase the problems you observed.
