  Thanks for your answer.

  setexpr command allows set the result operation in an environment

variable. But I want to set the result command (string) in an environment variable to compare it with the expect value.

Build it from parts. Start with putting the expected value in an environment variable, so you can use setexpr to compareit against the actual value. Then use conditionals to react as needed. Use standard shell scripting methods.

Best regards,

I added setexpr command, but I don't understand how to use it for my need.

For example :

u-boot# set expct "FF7F7F7F7F7F7FC2" u-boot# sspi 8 64 9F FF7F7F7F7F7F7FC2 u-boot#

This SPI command allows to read the NVRAM code ID, I want to compare with $expct unsuccessfully

u-boot# if test "sspi 8 64 9F" = $expct ; then echo Success; else echo Error; fi; Success u-boot# set expct "FF7F7F7F7F7F7FC" u-boot# if test "sspi 8 64 9F" = $expct ; then echo Success; else echo Error; fi; Success

$expct either equal to "FF7F7F7F7F7F7FC2" or "FF7F7F7F7F7F7FC" the result of if condition is the same.

Many Thanks for your help.

Khalid
