for k40 generated , how to force codewarrior linker generate 32bit aligned s19 file?
if Codewarrior can't, what tool can convert it?
In order to set the max length of the S19 records in the S19 file you have to go the the Project Properties window and under your C/C++ Build Settings find the linker output settings. You should have a setting for "Max S-Record Length" If you want to align the S-Records to 32 bits then you should set this to 4 (bytes). I am wondering why you need this particular alignment though... Are you trying to align the instructions on 32 bit boundaries or just the actual S-Records in the S19 file? If you are trying to align the instructions on 32 bit boundaries you should instead modify the lcf file to use ". = ALIGN (0x4);" for the sections of the rom/ram that need to be aligned this way. If you are just wanting to align the S-Records in the S19 file, I can't see any reason to do this unless your bootloader only accepts S-Records of a certain width, and it has been my experience that most of the bootloaders provided by Freescale work fine by setting the max S-Record length to 124 (128 - 4 for checksum).
Hope this helps!
