28x - unknown firmware

[alpacaman]

I bought 2 28x chips. When I go to program them I get an unknown firmware error. When I check the firmware it comes up with:

Firmware version A.2 (unknown firmware version 2)

This is my first attempt at using a 28x - please help.

I think only Technical can answer this fully, but;

Does your computer / Editor / cable "recognise" other Picaxe chips?
Do you have the operating circuit shown in Manual 1 p23?

My "old" 28X (from last year), is v8.

This should be on your computer in the
Programming Editor directory, titled “firmware”

*** PICAXE-28X (40X) ***
The PICAXE-28X (40X) firmware is implemented on a PIC16F873A (PIC16F874A).
BASE FIRMWARE CODE:7
V0  FIRST PUBLIC RELEASE 
V1  ADDED 16MHz OPERATION OPTION
V2  AMENDED CODE TO ALSO FUNCTION WITH 874A TO CREATE 40X PART
V3  INTERNAL GANG PROGRAMMER CHANGE
V4  ADDED 256 GOSUB OPTION
V5  CORRECTED MINOR SERTXD ISSUE
V6  UPDATED READTEMP/READTEMP12/COUNT TIMING.

V7  ADDED SINGLE BYTE READI2C/WRITEI2C SUPPORT. ROHS COMPLIANT

I wonder how old your chips are?

Yes - the cable does see other chips and I double-check the circuit.

I just bought the chips from HVW Technologies which is were I've bought the other versions of PICAXE chips.

These are 28X1 chips and your software is out of date - download the latest version and then select 28X1 mode.

Thanks guys for your help. I was unaware of the file that Eclectic mentioned. When I saw that the pic used for a 28x was different than the one I received I started to think that I may not have a 28x.

Then I received the post back from Technical which confirmed my thoughts - it's a 28x1. I downloaded the current programming software and everything is working as it should.

Thanks for you help.
