Hello,

Could I clarify which version of EVE Asset Builder you care currently utilising?

Just as a note, if a erase does succeed the blob would need re-programmed into the flash IC before it can be detected. It may be that an erase has completed and the subsequent write has failed leading to he blob note being present.

Best Regards,
BRT Community

I'm using EVE Asset Builder v2.10.2

EVE Asset Builder is reporting that it successfully erased the data but it's a false positive.  I can plug in the FT232HQ and it works fine identifying the blob and calculating the speed.

Anything else you need me to try please let me know.

Kindest regards

Hello,

Please note that the flash chip can still be accessed for reading and writing even without a blob.
Upon successful erasure, the flash chip will be detected as "Blob is NOT present."
