ST95040 Verify fails, immediately after programming OK?

Postby lakesidetech » 06 Feb 2020 02:44

I am programming ST95040 devices, and consistently receive errors when verifying, after successful verification during programming. This also happens with similar devices (25C040, for example). There are no specifics about the error, just that it failed. (What does "Status register: Data In: F0h, Data Out: F0h" mean??) I believe that the data is actually getting written properly...

Hello,

Please confirm which version of the software you are running. I ask because I can see that we modified the algorithm for this device in v3.56d. The current latest version (3.56d) is available on our website here: https://www.dataman.com/downloads/dl/fi ... ftware.zip

If the latest software does not improve the situation, please let me know.

Best regards,
