Hi Abhishek,
If your already having the conect records for the bonding atoms in your intial PDB file (present in the end of your PDB file) , using bond command again while making the initial parameter file mostly gives such an error.
regards
Sowmya

Check your atoms names carefully, seems like there is one name given to two atoms.

Subject: [AMBER] cannot add bond
Hi
I have been trying to create parameter file for my heteroatom.
I have calculated RESP charges and after that while creating prmtop and inpcrd files I am getting error.
!FATAL ERROR----------------------------------------
!FATAL: In file [unitio.c], line 1810
!FATAL: Message: 1-4: cannot add bond 8 9
This may be caused by duplicate bond specifications; for example, explicit bond commands in addition to PDB conect records.
!
!ABORTING.
Everything in structure looks good and connected as expected in mol2 file.
Can anyone suggest me what should I do for this.
With regards,
AT
