Unknown Guru

Does anybody know what this Guru means by running an app
80000004 002A8340 thanks

thomas · 19 August 2011, 09:12

80000004 means illegal instruction. The second number is the address of the task which abended. Without a memory dump (or access to the memory at the time of the crash) one cannot tell which one it is.

I'm sorry the Guru is 80000003 my mistake

thomas · 19 August 2011, 10:40

from exec/alerts.h:

Code:

#define	ACPU_BusErr	0x80000002	/* Hardware bus fault/access error */
#define	ACPU_AddressErr	0x80000003	/* Illegal address access (ie: odd) */
#define	ACPU_InstErr	0x80000004	/* Illegal instruction */
#define	ACPU_DivZero	0x80000005	/* Divide by zero */
#define	ACPU_CHK	0x80000006	/* Check instruction error */
#define	ACPU_TRAPV	0x80000007	/* TrapV instruction error */
#define	ACPU_PrivErr	0x80000008	/* Privilege violation error */
#define	ACPU_Trace	0x80000009	/* Trace error */
#define	ACPU_LineA	0x8000000A	/* Line 1010 Emulator error */
#define	ACPU_LineF	0x8000000B	/* Line 1111 Emulator error */
#define	ACPU_Format	0x8000000E	/* Stack frame format error */

Do get more info about the guru/error you can run debug tools like enforcer or muforce (needs MMU).

If 80000003 is Illegal address access (ie: odd) does the odd refer to one of the CIA chips because I’ve been getting GURU’s even running some of my script files and at random times.

thomas · 19 August 2011, 12:33

No, the odd refers to the address which is odd. 68000 can only access even memory adresses. Only bytes may be read from odd addresses.

For example

lea $40001,a0
move.l (a0),d0

will cause this guru.

It could be caused by running 68020 programs on 68000 (although this would more likely crash with illegal instruction).
Or it might mean that your RAM is damaged.

shrub3056 · 19 August 2011, 15:36

I’ve done extensive ram system tests and checked the integrity of the offending program all proved negative. Do you think it could be hardware related i.e. CPU or any of the custom chips?

Bamiga2002 · 19 August 2011, 17:26

Have u got an A1200? If so, I recommend caps replacement.

shrub3056 · 19 August 2011, 17:31

I’ve got a 500+ 2meg chip 8meg fast 4GB CF drive

MaxTransfer set correctly? Random crashes can happen if large data files are corrupted. Random "object is not a load module" messages can appear if large program files are corrupted. Large = bigger than 128K.

Could be some program you downloaded from Aminet, made for higher than 68000 and expecting the higher CPU to handle odd address word/longword addresses. If it's your own program, check that Asm-One or such is set to 68000 or it won't report odd address errors.

Where is the CF card connected to?

shrub3056 · 19 August 2011, 19:27

An AlfaPower 500 unit

Has anyone thought about asking the first question of them all?

What were you doing when this happened?
Which software and which version were you using?
Can you reproduce this error?

Does it happen "always" or just "sometimes"?

shrub3056 · 20 August 2011, 21:36

Well I’ve been trying to use a printer on my Amiga. I downloaded some drivers. I used DosTrace from Aminet and at the point of the crash it was calling the particular driver prefs was set to. It must be for 68020+ systems. Many thanks to all that tried to help.

Spot on jman.

Glad to be of help
