DUTCH:
Ik gebruik een hardware ISP programmer (Diamex prog-S) en AVR BASOM om een Atmega te programmeren.
Wanneer ik een Arduino Uno (via ISP connenctor) gebruik, werkte alles perfect.
Wanneer ik een breadboard gebruik EN ik gebruik de originele Atmega328P van het Arduino board, dan werkt alles eveneens perfect.
Als ik op Identify Chip klik in het programmeervenster, dan krijg ik te zien:

Atmega 328P, Flash : 32768, EPROM: 1024
Chip ID : 1E950F
STK500V2 detected
MAAR, wanneer ik een nieuwe microcontroller gebruik, dan kan AVR BASCOM de nieuwe chip niet identificeren !!
Als ik dan op 'Identify Chip' klik krijg ik te lezen:

Chip ID: FFFFFF
STK500V2 detected

Ik kan dan geen contact maken met de chip.

Ook de Atmega 644P20PU kan ik niet herkennen.
ISP is correct verbonden!!

Ik ga ervan uit dat dit niets te maken heeft met een bootloader omdat ik een hardware ISP programmer gebruik. Klopt dit?

Wat doe ik verkeerd?

Op voorhand bedankt om me te helpen.

ENGLISH
I use a hardware ISP programmer (Diamex prog-S) and AVR BASCOM to program an Atmega chip.
When I use an Arduino Uno ( via ISP-connector), everything works perfectly.
When I use a breadboard with the original Atmega 328P of the Arduino board on it, everything works perfectly.
When I click 'Identify Chip' , BASCOM gives the following message:
Atmega 328P, Flash : 32768, EPROM: 1024
Chip ID : 1E950F
STK500V2 detected

BUT, when I use a new controller, and I click 'Identify Chip', BASCOM gives this message:
Chip ID: FFFFFF
STK500V2 detected

Then, I can not make contact with the chip.

Also the Atmega 644P20PU can not be recognized.

ISP is connected correctly.

I assume that this problem has nothing to do with a BOOTLOADER, because I use a hardware programmer. Am I right?

What do I do wrong???

Thanks beforehand to help me!!!

English is sufficient here.

Likely the ISP-clock of your ISP-programmer is too high, it has to be not more than one quart of the system clock.
A new ATM328 out of the box works with internal RC-oscillator 8MHz and CKDIV8 fuse set, effectively giving 1MHz system clock, so the ISP-clock has to be same, or lower than 250kHz.
The Arduino Uno's fuses are set to run full speed with 16MHz, good for up to 4MHz ISP-clock.
Lower the ISP-clock of your programmer and you should be ok.

Hello,
if you use Arduino uno rev 3 and Mega 2560 rev 3 or others using AVR Maga ship, you need to follow the explanation gives in the Basom Arduino forumhttp://www.mcselec.com/index2.php?option=com_forum&Itemid=59&page=viewtopic&t=12472 or samples of Bascom

It use bootloader of arduino and the special programer option arduino and arduino STK500V2

If you use the ISP pin you need to use the option of your programmer
example : to program an ATMEGA644 I use ISP-USB programmer option

bon courage Wink

Hm, do you actually read the TO's question, before answering?
The TO has problems to ISP-program naked ATM328's.
Neither he needs an introduction to Arduino's, nor the advice to use an ISP-programmer in case of using the ISP interface.
The latter is quite obvious, isn't it? LOL
He uses ISP and it works with an Arduino with ATM328 chip, but it works not with a new controller.

Whenever you use the 6-pin ISP header of your Arduino, you destroy the bootloader.
However, you don't destroy the fuses. Make sure that you remove the BOOTRST fuse since you are not using the bootloader.

New virgin AVRs from the factory run on their internal RC clock @ 1MHz.
An Arduino AVR will run on the crystal / ceramic resonator.

Make sure that you have a clock. Make sure that your ISP programmer runs at 125kHz.

David.


problem solved !!!!!!!!

I could change fuse-bits afterwards to use 11111111 external oscillator.

Thanks a lot David !!!!!!!

That's not correct, you can read the flash, read and write the fuses. Only programming the flash via ISP destroys the BL.

You've obfuscated in your post somehow the true solution, which was actually described by the last sentence.
Just to make that clear, in case another user has a similar problem and will find that topic.
