Hi, Albert:
See the Denx U-Boot documentation, more precisely: http://www.denx.de/wiki/view/DULG/CommandLineParsing#Section_14.2.17.
From this web page, it seems hush-shell support "for" iteration. So, i wrote a simple script as below: for(i=1;i<10;i++) do echo "lion-0722" done
Then, i used mkimage tool to produce a script. Then, i load it to dram, and run it with autoscr cmd. But failed, the log message is: LION # fatload mmc 0:1 0 scriptcmd0722 reading scriptcmd0722 120 bytes read LION # autoscr 0 ## Executing script at 00000000 Unknown command 'for(i=1' - try 'help' Unknown command 'i<10' - try 'help' Unknown command 'i++)' - try 'help' syntax error syntax error ... ...
Did you try the commands live in your U-Boot console?
Did you make sure hush shell is enabled in your U-boot?
Best wishes,
Amicalement,
