Hi, I´ve been reading the training pps´ from AT91.com and I found an instrucion (?) in the Boot.s that doesn´t appear in the ARM7 Technical Reference manual as part of the instruction set. My compiler gives me an error because it doesn´t know the statement. It is the "DCD" instruction. Please, can anybody tell me what it is for?? And what should I do for my compiler to accept it?

Thaks.

Hello,

the software example you are referring to must be compiled with the ARM ADS development tools.

DCD (Define Constant Directives) is used to allocate space in memory. DCD stores the address of a routine that handles a particular clause of the jump table.

You must find out the equivalent instruction for the assembler you are using.
