LAUNCHXL-F28377S: "Failed unlocking device (zone 1) after reset."

Part Number: LAUNCHXL-F28377S

Hello,

In trying to reproduce a customer issue, I may have fouled up my launchpad. When trying to erase all sectors, I get the below error:

C28xx_CPU1: Warning: Failed unlocking device (zone 1) after reset.
C28xx_CPU1: Flash Programmer: Error erasing Sector B. FMSTAT value = 0. Operation Cancelled (0).

Is there any way to recover from this?

Thanks
