Help Needed with programming a chip

Сообщение ibby » Ср янв 05, 2011 10:51 pm

Hello Guys,

I need help with programming a SST 49LF080A 33-4C-NHE

I have a Willem Programmer with the PCB 5.0 written on it and have the SST chip installed in the bottom LPC socket.

I have selected the device through the file menu and can erase the chip and says "erase completed by check DQ7"

However when I load the Binary data into the program and click the program button it says
"error at 0x000008 Chip = 0x90 buffer = 0xF8"

I cant seem to get anywhere!
HELP!

What SW version and HW jumpers mode pcb3b/pcb5.0 ?
Are you getting valid ID reply ?
Blank check after erase process.

Hi,

I have the jumpers set to PCB 5.0 and using software 0.98D10.

When I press the "Electronic ID" it reads it as
Manufacture 0x90
Device ID 0x10

When I press the Blank Check ID it throws up a diffrent error
"Error at 0x000000 Chip = 0x90 buffer =0x90"

You are unable to handle erase and program without valid ID.
Check PLCC chip pins from side and bottom. Softly clean pins sideward.

Ok,

I have used a multimeter, and confirmed the chip is seated in the socket correctly.

Could this be a jumpers issue ? :?
WHere should all my jumpers be ?

thanks
