Re: [U-Boot] Is it necessary that uboot(mips) should read status register($12) before setting it

Hi Bruce,

MIPS Uboot works OK.Part of the code is as below.

Congratulations. Although I'm not sure what I'm congratulating on ;)

And my questions: 1.read status register($12) and save value to $10,but don't use the value in $10 to do anything. Because uboot overwrite $10.

2.Is it right?I can delete this code "mfc0 $10,$12" from uboot.

I'm sorry, but I don;t know what to make of this. Can you tell us if this code is from U-Boot and if so, in which file? Also can't you try for yourself if U-Boot still works after removing this instruction?

What exactly do you want us to tell you?

Cheers Detlev
