P59 flash kernel development

They go by many names, P01, P59, VPW, '0411 etc. Also covering E38 and newer here.

Whoo Hoo ... Another brick OFF the wall!

BDM works great!

In case any body wants the pin outs.

Code: Select all

 A-4  = GND    -> Pin 3
 A-7  = DS     -> Pin 1
 A-11 = DSI    -> Pin 8
 A-13 = DSO    -> Pin 10

 B-12 = BERR   -> Pin 2

 C-12 = RST    -> Pin 7
 C-29 = DSCLK  -> Pin 4
 C-30 = Freeze -> Pin 6
The Intel chip also requires +12v on WPP during Write, I do not have the location of WPP yet.

Oh what a relief it is!

Actually, you do. Look at the cad file I sent you. It's also in the images you stripped the meta data from.

I saw no locations in the images at all ... I'm talking about the locations silk screened on the board.

Whoops Sorry, Have not looked at the CAD file yet, maybe my bad ...

Gampy,

Do not apply anything less than 11.4 Volts, and no more than 12.6 Volts to the WPP pin. This info is from the Intel flash datasheet.

I see no Silk Screened locations in that image.

Thank you for the voltage warning.

I'm not understanding you when you say "silk screened locations."

The location you apply the 12 volts erase and write voltage to the Intel Flash chip (what the BDM calls WPP) is not on the 90 pin header. It's where the red and black arrows are pointing (the second close-up image only has a black arrow). Sorry about the blurry images. If you view the cad file I sent you, it will all make more sense. I hope this helps!

OK, now I understand what you mean by "silk screened locations." I'm slow sometimes...

Bah humbug, it looks like there is nothing around to textually describe it's location.

Thanks David
