Am trying to use GQ-4x4 to write the Amega328p. Read is good and blank works. Write works but fails to verify. Data is written to wrong place and garbled.
Any help greatly appreciated.

How do you know read is good?
What is the exact error? Data is written to wrong place and garbled? |

I am trying to burn a bootloader to an Arduino Atmega328p. When I read a chip that has a good bootloader and compare it to the original file they look the same.
When I try to burn the bootloader it does appear to burn and the only error is during verify. Error Message is:
Verify Failed, Address=0x007800, Device=0xFF, Buffer-0x0C
It also correctly reads the chip ID.
These made me think the read function was correct.
When I read from the chip, I see what is almost correct data about 11 lines down from the address it should be at. Have tried the slowest burning speed with not change.
Thanks,

Guess I will be returning this to Amazon.
I bought it to program the Atmega328 because it was listed by the manufacturer to work with it. Have not been able to write anything into any one of these chips. Read and Blank work fine.
Must be that either the GQ-4x4 is defective or that it really isn't possible for it to write one of these chips.

| The chip is listed in the supported list for many years. The problem may be related to something else. If you can send an testing chip to us, then the problem can be found and fixed. |

Will be glad to send you a chip. It is a stock factory Atmel ATmega328p, not a clone. Tell me where to send it to and ATTN: to.
Attached is an image file of what I get when I write all 11 to the chip and read it back. The eprom section of the chip works fine and the written data reads back with the same checksum.
The Flash part of the chip reads back as shown in the attached file.

It seems a software bug on this chip.
Send the testing chip to:
GQ Electronics LLC
