What programmer ? Built-in socket or adapter ?
SW, selected device ? Are you getting valid ID ? What error messages ?

Sivava 4.5 (from ebay). Built in socket.

098d5, sst49lf003,4,8 . In beggining no, after i download the scematic i test pin to pin the voltage and i found one fault soldering connection in the first input chip and after i fix that, i take valid id in all chips.

Now i can read the data from any chip but i cannot  write in any sst fwh chip.


Thanks for help again.

I manage to program SST49LF003A with a tip i found in some chinese guy, with like putting to program SST49LF004A. The problem is that in 3 and 8(2 of them)  i have, the programming stop in some 80% (around) in area of boot sector, is like the programmer thinking that this is the protected area and not touch it.
When i try with 3 and put the machine to think that i have put 4 this pass and program it at full.

Hello.

I have the same problem, almost.

Willem 4.5 (sivava) , FWH/LPC Adapter, SST49LF008A.
I can read. But I can't programming,only the 'original' dump.
If I try to write another dump..then give error...

The E.  ID is --- . But I don't know why.

Tired all verison of the program, but no result.


The 2 capacitators removed...The 'jumper' is removed...but nothing
Stop writing..Stop writing..when the modification 'deceted'....
it look like write potection....I don't undrestand

Please help!

Chip should return 0xBF SST, device ID 0x5A ---- . Name is not included in SW list.
Are you getting ID ?

What software used ? Apply 0.98d5 and programmer jumpers in pcb45 mode or SW 0.97ja and jumpers in pcb3b mode.

Do you apply programmer Vcc=5V ?
pcb45c has plcc32 fwh/lpc built-in socket. You can try on it, without adapter.

Check chip pins, clean softly with small glasfiber pencil.
