Atmel ATTiny85 programming help

[Anonymous]

Hello
I just build this programmmer and now I'm stuck with this issue
I'm trying to program this ATTiny85 smd pluged into an adapter and I'm getting this errors:


Regulator up and running after 0ms VPP=11.9V

Regulator up and running after 0ms VPP=11.9V

CHIP ID:FFFFFF
Unknown device

Writing code ... Error verifying address 0000 (0), written 78, read FF

completed, 0 errors
Writing FUSE area ... Error writing fuse: written E1, read FF
Error writing fuseH: written DD, read FF
completed, 2 errors

End (5.02 s) 258 errors


I checked and triple checked the extension as well as the main board for solder joints or other mistakes but nothing was found.
I tried using the small 8pin socket as well as the 28pin socket with pin 4 connected to GND... same error
I tested the hardware on the back of the main board with the extension atatched and all indicated voltages are where they should be (on pins 14-15-12-1-4 of U3)
The above fuses are set manually (they're also included in the hex file)
Where am I going wrong?
Did I miss something?

Just to double check, you are using the AVR adapter board for this?

If you have not already read this thread: http://sourceforge.net/p/openprogrammer/discussion/1096961/thread/9c8cea53/?limit=25#bc27

I have been able to program this chip with no problem. Have you been able to program anything else with your newly built programmer?

I have built three of these programmers and the second one always gave me a problem for reasons I could never figure out.

So
I have laying arround a 12F629 programmed long ago with a jdm programmer
Reading it got me to this:

Writing the recalibration hex file:

Verifying looks ok

So the main board seems to work just fine when programming the 12F629
Also doing the same programming with the 12-16-18/I2C EEPROM board is ok

I think there might be a problem with the (my) ATMEL extension board?
Unfortunately I don't have another Atmel chip to check this

Any thoughts?

[Mitrofan Bitca Adrian Iulian]

I tried to program again the chip with OpenProg v0.9.0
Here's what happened:


Regulator up and running after 124ms VPP=12.5V

CHIP ID:1E930B
Atmel 8KB FlashUnknown device
completed
Writing code ... completed, 0 errors
Writing FUSE area ... completed, 0 errors

End (11.06 s) 0 errors


Then reading the chip:

Regulator up and running after 0ms VPP=11.8V

CHIP ID:FFFFFF
Unknown device
LOCK byte: 0xFF
FUSE byte: 0xFF
FUSE HIGH byte: 0xFF
Extended FUSE byte: 0xFF
Calibration byte: 0xFF
Reading code ... completed
Reading EEPROM ... completed

Code memory:
(empty)

EEPROM memory:
(empty)

End (17.36 s)

Come to think of it something like this happened once with OpenProg v0.9.1

[Mitrofan Bitca Adrian Iulian]

Back again... I pressed on the chip/extension board and
Finaly I got this:

Regulator up and running after 0ms VPP=11.8V

CHIP ID:1E930B
Atmel 8KB FlashUnknown device
LOCK byte: 0xFF
FUSE byte: 0xE1
FUSE HIGH byte: 0xDD
Extended FUSE byte: 0xFF
Calibration byte: 0x48
Reading code ... completed
Reading EEPROM ... completed

So it's a contact issue and I'll have to resolder everything

But another problem appeared when verifying the chip:

Regardless of the 'FF' missing, the ATTiny85 in circuit just works
The 'FF' missing, in my opinion, has to do something with the software reading/interpretation of hex end of the line since it is the only 'FF' missing (and the only one at the end of the line in the original hex file)
... Now ain't life beautifull? ... It all worked out in the end :)

[LDSisHere]

I am glad your chip worked. I have not used my programmer for quite some time so I cannot give you much help beyond what I already have.

[Alberto Maccioni]

No problem with FF missing; memory is all 0xFF unless specified in a hex file line.
The save hex function will discard all 0xFF at the end of a line.
This has no effect on programming.
