CodeWarrior 2.7 linker trouble with WRITEx command

[mr_adam_lins]

Hi all, 

According to the linker manual, the commands WRITEx(expression) emit a byte, half-word, or word at the current location. There are a few examples of usage available, which led me to think that this should work to emit the byte 0x34 at the first byte of memory in myMemoryBlock:

   .mySection : {      WRITEB(0x34);   } > myMemoryBlock

However, this kind of syntax always results in the linker complaining about a missing identifier. Has anyone used the WRITEx commands in CodeWarrior 2.7?

(I'm also puzzled why LONG(), SHORT(), and BYTE() are apparently supported, but not documented.)

Thanks,

-Adam

Hello

I checked with engineering.

In fact PA linker doesn’t support  WRITEB, WRITEH or WRITEW command. You need to use respectively BYTE, SHORT and LONG instead.

A documentation change request has been submitted to get the reference manual fixed.

Syntax of BYTE command looks as follows:

      .example_data_section :      {       __startxxx = .;              BYTE(0x48); /*  'H'  */       BYTE(0x69); /*  'i'  */       BYTE(0x21);  /*  '!'  */      }
