I just want to know everyone that GQ-4X this chip READ/WRITE with swap bytes.
So if you have file that reads normal you need to SWAP bytes before you WRITE it back to chip. Otherwise you will have incorrect data. |

| Also I forgot to mention , swap bytes can be done with GQ-4X |

If you read the data and then write the data back to chip on a same programmer/software, then you do not need to do any swap byte.

In that case yes you are correct.
But if you need to use different file to write and it was read with different programer, then you need to make sure the how the file was read. If was read with no swap bytes , then you need to swap bytes before you write it with GQ-4X. |

All files saved should be in correct order standard. If not, then that is programmer software bug, mcsu fix.
The standard file can be exchanged between different programmers. |

Sorry to take this thread from dead, but that is one of my doubts right now:
1.- I am reading a 93C86WQ 16bit eeprom and the GQ-3X read it with byte swapped at once, why does the programmer do that? or is the data already in that standard?
2.- If it read in that order, can I swap bytes, modify the data, swap bytes again and write it back to the chip?

Point 2 - yes, you can do that.
The data is probably already swapped on the chip, due to the endianness of the processor in the device.
