** updated: mx1605 now in 3.03 beta software :) code updated to match
to enable the mx25l1605am2c in gq prog add the following line to the spi eeprom section of devices.txt - sadly its no faster than paralell willem on gq-3x but have been told is 10-12 faster on gq-4x, have gq-4x on way so will confirm when arives
Name="MX25L1605",ID="C22015",Class="W25X10",Category="SERIAL_EPROM",MFG="Macronix",Vcc="3.6V",CodeSize="2097152",Adapter="SOIC8-DIP8 or ADP-004";
to use this chip in the zif socket requires either the soic20 adapter - the mx1605 is a 200mil chip and will not fit in the soic8 / 16 adapters alternatively use the jtag/spi in circuit adapter and soic8 test clip
use the bottom section of the zif on the gq-3x, not sure which part it is for the gq-4x

The code size should be: CodeSize="2097152"
Do a blank check to make sure the chip is erased completely.
The ID seems not working. The correct ID is ID="C22015". You can put ID="XXXX" for now.
OR
you can skip the ID check by uncheck the ID Checkbox.
see:
The ID issue can be fixed later.
Do you have picture on how the testclip working? |

FFFFFE was the id reported by GQUSBprg initially
you are correct about the data size, not sure what happened to my maths there!
sadly its no longer a 12 second read / write operation but it is now accessing the full storage capacity of the chip
would it be possible to get a real guide for devices.txt? - those few lines of info in the nanual and in the header are not that helpful
at the minute im just using an soic 8 pin test clip to connect to the removed chip, i hadnt noticed the in circuit adapter when i bought the 3x but as im concidering upgrading to the 4x for its jtag support i'l be ordering it then
only thing holding back my upgrade is m query to sales about the price difference between the 4x light and full pack as the fullpack says its just the light with free bonus pack - but its priced 8.80gbp more :/

| big issue: - despite specifying 3.6v in the config file the programmer is using 5v to power the chip, any suggestions? |

How did you measure it?
Check the voltage with the chip. |

| dmm across ground, power and data pins of chip, both power and data pins are all at 5v instead of 5v - of some concern as the chips only rated for 3.6v |

did you measure VCC with the chip connected?
The signal 3V and 5V are compatible TTL standard. no problem to mix them. Except the VCC.
Some 3.3V chip pins may be able to take up to 12V voltage. Example pin 3 on MX25L1605 accept 10.5V voltage. |

how do you arrive at the ID="C22015"? there is nothing in the data sheet to state this so is it something generates by the programmer or the software? |

thanks, i dont have that table in my datasheet :/
can this thread be locked or deletes now as the 3.03 renders this thread redundant
also re 3.03... the daapter for this chip needs to be the soic-20 adapter, as itsa 200mil part it will not fit in the soic8 adapter |

Yes. The MX25Lxxxx SPI chips will be formally supported from software revision 3.03 and later version. So this thread should be locked and become the history.
Thanks to nampilys for all of the contribution on this device. |
