how to include vector table data file

shilpa1 — Fri, 18 Feb 2022 05:22:02 GMT

In my project (MIMXRT1176) i have a file auto-generated , exported directly from the _lib.xls(Library Master Spreadsheet).
the file is .src data file. How can i include this file in compilation. Is it possible by enabling any gcc flag ? or the file require complete modification.

My file looks like

AREA REL,PIC,READONLY,ALIGN=4

EXPORT text
EXPORT txttbl

a EQU 1
b EQU 2
c EQU 4
d EQU 8

;xy must always be the first element in this table

text
base

xy DCW 1
DCB 0
DCB "START",0
DCB "",0
ALIGN 1
zw DCW 2
DCB 0
DCB "** * processing * **",0
DCB "",0
ALIGN 1
.

ALIGN 2
txttbl
DCW xy-base,zw-base
DCW .-base,.-base
.
.

END

Hi，
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
Before answering your question, I was wondering if you can introduce your testing environment, such as IDE, source code, etc.
Have a great day,

Hi,
Thanks for your reply and clarification.
According to your statement, it seems like you want to contain a customized file (.src data file) to the SDK library demo, in my opinion, it's unavailable to do it, moreover, the SDK library demo also has provided the vector table data, it's unnecessary to add a customize file to replace it.
Have a great day,

I could like the clarify my exact situation.
I have the armasm file, which holds the look up table for my implementation (something similar to the one i mentioned above). This file is not taken up in compilation even we force it to compiler its format is not supported. how can I include this in my c project.

Hi,
Thanks for your reply and clarification.
The MCUXpresso IDE use the arm-none-eabi-gcc to compile the code project, I'd like to suggest you check the GCC compiler whether can support your file by referring to the guider.
Have a great day,
TIC

Hi @shilpa1 ,

see https://mcuoneclipse.com/2022/02/18/using-custom-source-file-extensions-with-eclipse-cdt-gnu-make-builder-projects/ how you can include a file with a custom extension.

In your case, you need to assign the (GNU) ARM assembler. Keep in mind that in order to assemble your file by the assembler, it shall be written in the GNU assembly syntax. See https://gcc.gnu.org/onlinedocs/gcc/Basic-Asm.html#Basic-Asm for some details on this.

I hope this helps,

Erich
