Immediate offset problem with the LDR commands

Bulent Unalmis

Compiler give error message for following codes.
A1174E: "Data transfer offset 0x00000102 out of range. Permitted values are 0x00..0x1F"

    LDR   R1,=USB_BASE
    LDRB  R0,[R1,#USB0_CSRL0] ; Error code is A1174E !!!!

USB_BASE   EQU 0x40050000
USB0_CSRL0 EQU 0x102

But compiler dont give any error if i write this program thats way

USB_BASE   EQU 0x40050000
USB0_CSRL0 EQU 0x102

    LDR   R1,=USB_BASE
    LDRB  R0,[R1,#USB0_CSRL0] ; Error code is A1174E !!!!

    This place is technical forum.

    More to the point, it's a dicsussion forum. You don't seem to know what that means, though. You come here not just expecting, but outright demanding that everybody agrees with you, simply because you say so. That's not discussion, that's attempted dictature.

    And since the subject matter of this forum is of a technical nature, you come across people who don't just hold opinions, but actually know things for a fact.

    (Let wait the new version of assembler compilers)

    Let's, indeed. If only you would shut up til then, we'ld all be better off: you'll be indulging in your own self-righteousness, and we'll be enjoying your silence.
