How generate a s19 with longword address

eddv — Wed, 02 Dec 2009 22:06:28 GMT

Hi coleagues,

Can somebody help me this tricK? I need to generate a s19 file with 32 bits of address. In .list file, I get: just put LLEN 32 on the file thatthe address in this file appear in 32bits, but, in s19 file, is put just the address needed. For example: if my code (or data table) start at $0100, the s19 uses 2bytes. If starts as $100000, the s19 file uses 24bytes to specify the address. If I put my data at $01000000, then compiler just put 3bytes in s19 file.

My question is: how force it to use 4bytes in s19 file?

Thanks by any help!

Do you want burner to generate S3 records only? Try replacing in burner.bbl

SRECORD=Sx

SRECORD=S3

Thanks, kef, but...

I do it, but doesn´t work...

The compiler act haw the sx mode is selected.

To generate in a file called "nonono.asm.sx" (asm.sx type), is the same mode?

What target we are tlking about? I just

1) created empty new XD64 project

2) opened burner.bbl file

3) In burner.bbl found two instances of SRECORD=Sx and replaced that to SRECORD=S3

4) hit make

Resulting S19 file (long S0 record removed). Please note 32bit addresses:

S3200000C000CF3100C6055B134A800BFE4A8000FE0000C015C0190000000000009D

Resulting GLO file:

Hi kef,thank for your help!

Your last message help me, but not how I need:

Maybe explain in other way:

I need to compile a file that is just a table, to put it on a SD card, somethink like this:

Source file:

    LLEN   32        ; OK, in LIST file, 32 bits is ok.

        ORG   $10000000    ; need 32bits for address
    DC.B    $55

Now, I add this file at "Sources" tree of CW, and click in it with mouse right button, and select Compile item.

The compiled s19 I can get now: (with extension ".asm.sx")

S05300..... (header...)
S104000055A6 <--- here I want 32bits address It must be S
S9030000FC

BUT:

they put my $55 byte at $00 00, not at $10 00 00 00 how I need.
I need a s19 file like this:

...
S3061000000055XX , where XX is the normal check byte
AABBCCDD - 4 byte address

Maybe I doing something wrong....

My really big problem is that I cant generate a S19 file with 4bytes of address, where the address is higher than $00FFFFFF, in other words, when the address is $01xxxxxx or higher, the compiler generate a s19 with address $00xxxxxx -it cut out the MSByte.

Any helps are welcome!

I see now. Linker seems to not support addresses above 2^24, emits L1408 warnings. But maybe you could setup bbl file so that some addresses <0x1000000 will be moved above >=0x1000000.

The problem seems to be is in assembler, maybe, because to solve this I learned to use the ahc12.exe, using without CW "skins", and they not generate S19 file correct too.

When my source is:

    LLEN   32
        ORG   $10000000
    DC.L    TiLEIT_000 ; just some labels to tables

DC.L TiLEIT_001
DC.L TiLEIT_002

...

The s19 IGNORE a MSByte and generate this:

S0100000483A5C56696E6353782E70726D39
S325000000000300000000010A0000010C0000010E000001100000011200000114000001160060
S325000000200001180000011A0000011C0000011E0000012000000122000001240000012600BA
S325000000400001280000012A0000012C0000012E00000130000001320000013400000136001A
S325000000600001380000013A0000013C00000140000001420000014400000146000001480070
... [00 00 00 60] Wrong addr, must be 10 00 00 00.

and, tryng a lot, I see this: when I star from 24 bits and after, the address goes to 32bits (one byte more)

    LLEN   32
        ORG   $FFFFE0
    DC.L    TiLEIT_000

DC.L TiLEIT_001
DC.L TiLEIT_002

...

The s19 continues from correct address and goes to $10000000-

s19:

S0100000483A5C56696E6353782E70726D39
S32500FFFFE00300000000010A0000010C0000010E000001100000011200000114000001160082
S325010000000001180000011A0000011C0000011E0000012000000122000001240000012600D9
S325010000200001280000012A0000012C0000012E000001300000013200000134000001360039
... correct addr [01 00 00 20]!

I need to force they to always 32bits, but how?

For the S12 the EABI defined in ELF the addresses to consist of a 24 bit offset and a 8 bit part for the address space. That's why you wont get a >24 bit address when using an ELF file.

What you could do:

- use the offset method with the burner as pueraroposed bu Kef (if the whole address range you have to cover fits in 24 bit)

- Use some other tool to create the srecords. Could be another assembler or also some simple script (I did emit srecords in tcl in the past (don't have that script anymore), in the end the srecord format is so simple that they can easely be generated in language. You could also create a binary file and use the burner to convert it to an srecord.

BTW: Why do you want to create those srecords for?

Hi,

Ok, how can I create a binary file with CW tools?

BTW: My project has a XDQ512 that contain the program, and a SD CARD with 2GB, that contain the datas, images, etc...

I will use a s19 to read it by one program that I made, and sent it for uC, and uC write the datas on SD card. I intend to usea s19 because its ease to read, but could be a binary file too, or another way to get te data compiled.

Any suggestion are welcome!
