Lpc2000

Hello ppl,
  I am using the GNU tool under the Keil environment. I wanted to know if there is anyway I could make a lookup table(in code memory, flash) from a particular location.
 
for eg..some assemblers support the following:
 
org 1000h
db 25h,34h,45h
 
so the data is stored from 1000h onwards. Is there any equivalent facility in GAS(GNU assembler).
 
Also is there any place where I could find gcc documents specfic to ARM other than the hitex book. It would be really helpful.!!!!
 
Thanks in advance.
 
Vineet.

You can use an __attribute__((section(".lookup_table"))) and create a 
section in your linker script. I used the following linker script for 
some calibration data in a LPC2292:

MEMORY
{
  CONF  (r)  : ORIGIN = 0x00038000, LENGTH = 0x00006000
}

SECTIONS
{
  .calibration :
  {
    *(.calibration1)
    *(.calibration2)
    *(.calibration3)
    *(.calibration4)
    *(.calibration5)
    *(.calibration6)
    *(.calibration7)
    *(.calibration8)
  } >CONF
}

Hello Vineet,

documentation can be found under:
http://www.gnu.org/software/binutils/manual/gas-2.9.1/as.html

Why you want to build up such lookup table in assembler?

 Do you need a tiny and efficient real time
