8051 linking EROR: "L6320w" reset_handler

Chris Page

hi, im an 8051 noob and trying to run this example program supplied by ARM for students;

AREA eval_proj, CODE
ENTRY
LDR r1, =0x03FF5008 ; r1 = IOPDATA address
LDR r3, [r1] ; r3 = memory[IOPDATA]
LDR r2, =0x10 ; r2 = LED offset
AND r3, r3, #0 ; r3 = 0x0 (light LED0)
Loop LDR r5, =0x0500000 ; r5 = delay counter STR r3, [r1], #0 ; IOPDATA = r3
B Delay
Resume ADD r3, r3, r2 ; add offset ADDS r4, r3, #-256 ; if r3 = 256 BNE Loop ; done SWI 0x11 ; terminate program

Delay SUBS r5, r5, #1 ; delay loop BNE Delay B Resume END

the program compiles but i keep getting the error:

eval_proj.axf: Error: L6320W: Ignoring --entry command. Cannot find argument 'Reset_Handler'.
eval_proj.axf: Warning: L6320W: Ignoring --first command. Cannot find argument 'Reset_Handler'.

although one is a warning the file is not linking and therefore i cannot debug it. i think i need to change something in the configuration

help please! chris!

    That's ARM code - why have you titled your thread "8051...", and selected C51 as the toolset?

    Obviously, ARM code won't work on an 8051, nor with the C51 tools!

    Also, please take care to read the instructions for posting source code:

    Note that TABs don't work (well) - use spaces instead,

    and don't forget to check it in the 'Preview'...

    Sorry, im writing 2 programs one for ARM and one for 8051, i got confused! That is ARM code for the ARM7TDMI core internally within the Samsung S3c4510B microprocessor.
    And yes, ill read that about the posting of source code.

    Ill just report the source code:

                    AREA eval_proj, CODE                                    ;AT 0x00008000?
                ENTRY
                LDR     r1, =0x03FF5008                                 ; r1 = IOPDATA address
                LDR     r3, [r1]                                                ; r3 = memory[IOPDATA]
                LDR     r2, =0x10                                               ; r2 = LED offset
                AND     r3, r3, #0                                              ; r3 = 0x0 (light LED0)
Loop            LDR     r5, =0x0500000                                  ; r5 = delay counter
                STR     r3, [r1], #0                                    ; IOPDATA = r3
                B               Delay
Resume          ADD     r3, r3, r2                                              ; add offset
                ADDS    r4, r3, #-256                                   ; if r3 = 256
                BNE     Loop                                                    ; done
                SWI     0x11                                                    ; terminate program

Delay           SUBS    r5, r5, #1                                              ; delay loop
                BNE     Delay
                B               Resume
                END

    I don't see how your error message has anything to do with the code you posted. Are you using a correct startup file (hopefully you don't use a C51 file in your ARM7 project...) ? You should find a label called

    Reset_Handler

    there, which is where the processor starts fetching instructions.
