                      | Hi guys, I don't get the time to get on here much and am new to the whole programming thing although I am an electronics & AV tech by trade.
 
 I have read the User Guide several times over but cannot seem to figure out why I am getting error messages on the USB programmer software. I have tried many different settings and although I did initially make successful write, verify and blank checks it appears I now cannot.
 I am getting these messages:
 
 verify failed, Address=0x00050F
 device=0xA8,Buffer=0x88
 
 and also
 
 device blank check failed at address 0x000200
 read=0xC3
 =0xF7
 
 I have tried to change the "Fill Buffer With Data" text fields but come up with the same types of messages just with varying address'
 
 Using a ST M28F102 EPROM
 The only thing I could think of is getting the spec sheet on this chip and checking it against any default data loaded by GQ USB programmer software but not sure.
 
 Any help would be greatly appreciated.
 
 Cheers,
 
 James.

                      | M28F102 is a flash chip, you can check the chip ID to make sure your software is setting good. 
 Then erase the chip and do a blank check.
 
 If the chip is blank, then you can write new data into it.

 Yes I already know this hence why I am asking about the error messages when I try to do this..
 It was working the last time I wrote data to it etc,.
 Thank you anyway.

                      | Does anyone know what the File Offset is meant to be for an ST M28102-120ZK1? I don't understand the File Offset and Device Offset properties that are assignable in the GQ software, are these parameters set by the chipset manufacturer I need to fill into these fields?
 Is this the case also for the "File Buffer" setting?
 Thank you in advance

                      | File Offset is to set the data start address offset when loading a data file. Device Offset is to set the data start address offset when writing  the data into chip.
