Hi, I have a Dell Latitude 3420 with eprom model GIGADEVICE 25R256DYIG and I try dump Bin file with a programmer CH341 but the software doesn't recognize the chip. I tried with and without voltage adapter for 1.8V.

I tried several Softwares versions, but these doesn't works.

Anyone has some ideia why this doesn't work? I read some papers saying that the programmer CH341 doesn't support this eprom 25R256DYIG.

I appreciate any help!

Thanks.
