Hi all
I'm trying to write a st M27512F1 without success with a GQ-3X
It's a revision 1.50
I've tried 6.14, 6.11 & 5.03 version of the program
Usb driver 2.0
2 different chips
different speeds
The programmer reads the chip ok.
but always the same error: "write failed, address=0x000000 buffer=0x39, device=0x00"
What i'm doing wrong?
thankyou in advance.

If your chip has a top glass window, then it needs UV eraser to erase it. |

Hi
Yes, the id is well recognized
But i believe it's my fault, cause the M27512F1 is an EPROM (not EEPROM)
this kind of chip needs to be UV Erased first if i understand correctly, I bought an UV Eraser from ebay, when it arrive i'll see...
any idea about this? i'm right with this?

Does it ID the chip correctly?
Does the programmer works with onther brand 27512 chip? |
