[U-Boot] strange behaviors with setexpr syntax error and '==' != '-eq"

[Clément Péron]

Hi,

I write a script on u-boot but i found 2 strange behaviors.

The first one is when I try to do a mask from a memory address and
store it to an env variable.

=> setexpr toto *{loadaddr} & 0xFF
syntax error
=> setexpr toto *{loadaddr} & 0x3F
syntax error
=> setexpr toto  0x3F & *{loadaddr}
syntax error

The second one is the difference between '==' and '-eq'

=> setenv a 1
=> setenv b 2
=> if test ${a} -eq ${b}; then echo toto; fi;
=> if test ${a} == ${b}; then echo toto; fi;
toto

Which doesn't seem logic.

Could you please explain me these behaviors ?

Thanks,
Clement
