Hi,

I have an EZUSB Cypress AN2131SC chip and would like to program the 8051. All I would like to do is set address 0x7f96 to 0xff.

My test.asm file contains:

        .area CODE (ABS)
        .org    0x00
        mov 0x7f96,0xff

I compile it using:

asx8051 -losx test.asm

(version: ASxxxx Assembler V01.70 + NoICE + SDCC mods + Flat24 Feb-1999 (Intel 8051))

Then generate the ihx file:

aslink -c
ASlink >> -i
ASlink >> -m
ASlink >> -x
ASlink >> -u
ASlink >> test
ASlink >> -e

(version: ASxxxx Linker V01.70 + NoICE + SDCC Feb 1999)

Hex output is:

:0300000085FF96E3
:00000001FF

Then transfer it using fxload:

 sudo fxload -I /home/dan/test.ihx -D /proc/bus/usb/002/003 -vvv

(version: Sep 5 2007 (development))

Unfortunately I get the following error:

microcontroller type: fx
single stage:  load on-chip memory
open RAM hexfile image /home/dan/tacx/test.ihx
stop CPU
** LINE: :0300000085FF96E3
record too short?
unable to download /home/dan/tacx/test.ihx

I am new to this so I would be grateful if someone could explain what I am doing wrong.

Thanks,
Dan
