39SF020A programming with Willem PCB5.0

Сообщение marius240288 » Вт дек 28, 2010 10:31 pm

Hi! I'm beginner in programming and i have bought a new Willem PCB 5.0 programmer. The problem is that i want to program a 39SF020A chip from xbox 360 drive Hitachi LG 47 and i don't know how to program it with this programmer. I have also the adapter and i have soldered the chip on it. I plugged in the lpt cable (ECP) and usb cable and i have also installed EPROM50 and EPROM3 from sivava's cd. I selected
39SF/49F020 from Device and i loaded the bin file and when i try to program the cip remains on 0%. When i click to Erase Chip it works but programming it no. It doesn`t matter If i take out the adapter with cip from zif slot, the problem persists with or without the cip and adapter. I mention that when i click erase cip or read the green led from adapter is on. When i click VPP the red led is on. I don't know how to program this cip. I have soldered very good the cip on adapter also i made a picture. Thank you for helping me!

Wrong adapter (FWH/LPC) applied.
SST39SF020A is flash memory, TSOP-32/DIP32 adapter required.

Thank you very much. I don't have that apapter now and when i will buy it i will tell you if it works or not. Is there a way to bulid my own adapter without buying? I don't have the schematic diagram.

Look here.
Schematic is simply - get datasheet , find DIP-32 and VSOP-32 pinouts. Wire equal signals/pins 1:1 for all 32 . Usually here is 2 diods and jumper in Vcc line for 3.3V chips, but you can skip - 39SF020 5V flash.
Some simply designs and pictures attached. Note, extend tracks for 14mm size support.
