Flashing St M29f002bt70n1
« on: February 27, 2004, 12:11:00 PM »
Hi

I`ve a 1.4 box (10-10-2003) with ST M29F002BT70N1 chip, and this s**t don`t flash.
I doublechecked the solder points. Repaint them about 10 times with defrogger reapair kit paste. (Also that one is on the back of the mainboard)
I tried raincoat 0.7 and 0.501 also, with no success.

Any idea?

It says:

"INVALID MANUFACTURER ID: 0x09
Check that your flash-enable points are correctly soldered, that the
neighbouring circuitry is not damaged, and that any A18 or A19 switches
are correctly set.
Valid manufacturer IDs can be found at:-

But the pins are 100% closed...

I downloaded raincoat 0.7 from: http://www.geocities.com/mspritch/raincoat.html
When I try to read the original bios it says: 151 types read....  and after that: INVALID MANUFACTURER ID: 0x09

I am 100% sure the pins are correctly connected. I did it about 40-50 times before...

they arent bridged, make sure there arent any broken traces anywhere, check with a multimeter

Ok I`ll check them tomorrow. And what about that point at back of the board. So it must connected, or not? Is that 2 on top is enough?

2 on top should be fin, but if your having trouble it never hurts to have a little redundancy

They COULD be bridged, but if the resistors near the jumpers are bridged or removed, you'll get the same problem.

Did you ever get this to work??? I've got the same problem. Also I noticed in the raincoat.conf file that St M29f002bt70n1 isn't listed in the copy of the .7 that I have. Was it in yours??? If you've fixed this please let me know what you did. :D

This entry...
QUOTE (raincoat.conf)
Flash = 0x20b0,"ST M29F002T/NT/BT/BNT",0x40000

does the trick.

See here (scroll to page 17) to find out why.
