Hello from Mario, Germany.
sorry to ask for help, but after loosing many days of „try and error“ with a Willem PCB3B and 5.0T I am still unable to read a ST29W800B completely. verify or Programming returns an error at around 12,5% of reading.
with an arror At 0x0020000. ..
Because it is always near or at the same Address, I can‘t imagine, it is a „ floating line.
I use an older Willem3B and due to the problems, I ordered a newer willem 5.0T.
I also tried several programmer-softwares an different Computers. they all make problems.
Actually I use Win11 with an additional PCI-e LPT Riser-card. HW-Detection and PIC- Reading/programming is also ok.
HW detection and Flash-Chip identification is working, reading „look“ ok, but verify and programming NOT.
I assume, the Chipis not read completely, because it looks like some address-ranges are repeated.
Address-lines were tested, using Hw-test.
The TSOP48 Adapter is connected with two lines(cables) for A19 and A20. I also tried the 8-Pin Flat-Cable, that was delivered with the Programmer.
3,6V were selected. the Dip-switch config is set, like the program shows for AM29F800. can‘t select the 29w800.
Actually I am on a short trip, but I can deliver some pictures tomorrow, when I am back and show, what I use and how it has been set.
Thanks for your help.
