W25X80VSIG connect Issue...

[songokuaka2]

Hello Guys,

through my experiences with this forum I am on the road to ask again for help:-) (Thanks for every ones help)

My newest Problem is to "connect" a W25X80 SOIC Chip to my Willem PCB5a. I haven´t found a useful adapter between the items I get with the willem (only a small ICSP Circuit for 24XXX and 93XXX) My question now is how do I connect the Chip to the Willem PCB. My first try was to wire the Chip and stick it ends in the 25C80 Port, but it doesn´t work so as I want. Through my Web research I found out that these Chips are burnt in/with ZIF Sockets.

My Question is also, how do I connect the 8 Pin Chip to the 32 Pin ZIF on my Willem. What do I have to be aware of? Please help me with this Task and help reanimate my Laptop;-) The Chip inherit it´s bios.

Yes, you have to connect/place to/in 25Cxx 8pin socket.

...but it doesn´t work so as I want.

Programmer should be modified to support 3.6V on serial devices.
Latest programmers (pcb5.0 from Sivava, ...) are OK, yours version unknown.
Remove jumper (Open 3.6V), go Test H/W, activate 32-Vcc , and measure voltage on pin 8 (socket 25Cxx)

Through my Web research I found out that these Chips are burnt in/with ZIF Sockets.

Not possible on willem programmers. What link do you refer ?

Hello,

I use the sivava PCB 50a I think it´s the latest. I have connected the pins with the Chip, but when
I try to read I get only "FF 00 FF 00 FF 00 FF 00 ...." And when I try to write to the Chip I get an
Chip = 0xFF buffer = 0x21 Error at 0x00000000 .

I have selected the Device with the Name "25x080" and removed the Jumper to have only 3.7V to work with.

I measure 3,658V when I hit the Checkbox under H/W Test and when I deactivate it 2.627V. Is this okay?

Is the Chip broken or are these readings normal? Something isn´t okay about this Chip because a few Days earlier I could read some Information out of him.

May I ask for your opinion?

Remove chip to measure voltages on 25xxx socket pins.

Hello there,

thank you for your help till now. I have measured the Socket a second time and I get only a reading on Pin 5 with 4,371V No other Pin has voltage on it. Is that okay? I don´t believe it-___-"

Maybe I measure wrong, but Ground should always be Pin 4, right? Maybe you can now pinpoint the problem why my willem makes my live so hard.

In the meantime I get an SOIC8 to DIL8 Adapter in which I can plug in the Chip, but results doesn´t change. I buyed it to overcome the feeling that my solder skills are worse^^ But hopefully they aren´t.
