Hello,

Here is the link of CY91520 Chip Errata:

To analysis the issue, still I would like to suggest you use our Flash MCU Programmer to check if you have the erase issue in our tool?

And how many boards with the new MB91F526LSB devices do you have? If all of them have the same erase issue?

For further analysis, please kindly get in touch with Cypress local sales team or distributors to get local help.

Best regards,

Amy Wang
