I've added the device to the list, connect the adapter and it reads only 00000.... from flash. When I disconnect the flash it reads FFFFF...., when its connected it reads: 00000... And the programer can't erase or write, only read.
Connection is OK. Address line, data line. Whats wrong?
Thanks |

Read all 0000 means contacting is poor.
Check chip orientation, adapter type. You should be able to get Correct ID before doing anything else. |

Try this line, it should be better.
Name="SST39VF080",ID="BFD8",Class="SST39LF/VF040",Category="FLASH",MFG="SST",CodeSize="1048576",DIP="100011110101",Adapter="TSOP40A-DIP32",Message="Set the adapter to 5V VCC jumper position.";
OR
Name="SST39VF080_",ID="BFD8",Class="SST39LF/VF040",Category="FLASH",MFG="SST",CodeSize="1048576",
DIP="100011110101",VCC="5V",Adapter="TSOP40A-DIP32",Message="Set the adapter to 3.3V VCC jumper position.";
Please let me know if anyone works. |
