Any one use it, if so how do you program a SST 27SF512 chip
I select the SST 27SF512 chip in the program, erase it and
select my bin and program lt programs it, but when I put
it in my car the fans go on, so it's
in limp home mode. what am I doing wrong

 

did you double check your offset when you went to reprogram. I just did a few today

http://www.moates.net/manuals/FlashAndBurn.pdf

 

if this is tpi $8d the offset for a 32k is buffer start 000000 -> 007FFF end chip start 008000 -> 00FFFF end.

 

Doesn't selecting the SST 27SF512 chip in the programmer 2 take care of the off set

 

no the offset can be changed that is just a setting for the chip. If you put the information it the wrong address your car will go into limp home mode made that mistake today. lol

 

a 27sf512 is larger than a 27c256 so the information needs to be in the correct address.

 

How about a 64k what is the start and stop

 

64k what mask are you using ?

 

never mind it's 8d so it's 32k right

 

um ok

 

8d 32k. right

 

$8d mask would be a 32k .bin size correct

 

My pocket programmer2 has
buffer start
device start
device end
thats all what do I put in each line

 

this was answered in post 3

 

I don't understand this -> what does that mean

 

Can you please tell me what to put in each line please

 

buffer start 000000
buffer end 007FFF
device start 008000
device end 00FFFF

 

I don't have a buffer end thats my problem

 

Only a buffer start no end

 

Here is what pocket programmer web site had to say


To program a 27SF512 chip from a 27C256 file

select 27SF512
Set start of device to 8000
Load buffer with a 27C256 sized file (you can check the file size - right click on the file and select properties it should say 32K (32K*8 = 256K)
program chip
set start of device to 0000 so you don't screw up on your next chip.
If you have problems with this - please don't call us.

 

Thanks guys for putting up with me.
Everything is working fine now
Thanks again

 

 

what was the issue ?

 

The brain took the night off, this morning it was clear, went
through the posts and followed your instructions, worked
the first time, THANKS
