Burn Atmega128A with USBasp

muhit313 commented 2 years ago

Some days ago I bought one Atmega128A and one USBasp for new my project. Because I need more then UNO memory. But I am little bit confused about how to burn the bootloader of Atmega128A with USBasp. Because there is no schematic for USBasp. So I try it myself as: USBasp...............Atmega128A MOSI>>>>>>>PE1(PDI) MISO>>>>>>>PE0(PDO) SCK>>>>>>>>PB1(SCK) RST>>>>>>>>RESET VCC>>>>>>>>VCC GND>>>>>>>GND

And then try to burn the bootloader using your MegaCore. But I am unsuccessful. It gives me error. So can anyone help me about the Schematic for USBasp and how can I burn and program the Atmega128A chip with USBasp.

Note: I also read other issue and most of the solution is using USBtinyISP. But i don't have USBtinyISP. So Please suggest me Schematic for USBasp. I can manage FT232RL or CP2102 USB to TTL UART Module. If there is any chance to work with them.

avrdude done.  Thank you.

The MOSI pin on the USBasp connects to the PDI pin, and MISO on the USBasp connects to the PDO pin. See the minimal setup schematic for 64-pin AVRs. If you're still not getting it to work, it may be because the USBasp programmer is too fast for the microcontroller. You can then use the "USBasp (slow)" option when you burn the bootloader.

What do you use as the clock source? A 16 MHz crystal or the internal oscillator? Is the chip brand new/factory reset, or has it been used for something else before?

muhit313 commented 2 years ago

The minimal setup schematic for 64-pin AVRs is little bit confusing for me because there is no UART header in USBasp . So how can I connect DTR,Rx,Tx etc?

I also use the "USBasp (slow)" option when I burn the bootloader. But no luck.

I use clock source as internal oscillator. Yes the chip is brand new and not used before.

tomaskovacik commented 2 years ago

obviously, if you do not have a serial interface, then do not connect it?

anyway, this works for me most of the time: try set internal oscillator to 1MHz plus "USBasp (slow)" => burn bootloader then change it to your desired speed with "USBasp (slow)" and then is should work also with standard usbasp

muhit313 commented 2 years ago

Thanks a lot to all of you. After 2 days hard and soul try I can see the success. May be I try all of the possible way that I can. I think the chip is only used with 16Mz crystal. Because I am unable to use the 1/8KHz Internal crystal. If I want to use them then I will faces this kind of error. So finally I put 16KHz crystal and select USBasp slow(MegaCore) and its working fine. Thanks again to all especially @MCUdude for his support and this nice board.

MCUdude commented 2 years ago

Great to hear you figured it out! What probably happened was that the chip was already set up to use an external crystal, and it then won't work without it, and you can't communicate with it using a programmer.

You can now select the internal oscillator in Arduino IDE and burn the bootloader again, but you can also continue to use it with a 16 MHz crystal.

muhit313 commented 2 years ago

Yes you are right @MCUdude . Sorry for another comment. Now, I can use usb to ttl or USB to Serial adapter or FTDI to program and open serial communication. Because my USBasp may be not support serial communication.

Thanks for your great innovation.
