Hi,

I am unsure what you are asking. If your device is locked, you will need to unlock the device prior to programming the flash.

As Sal mentioned, you need to UNLCOK the device by writing correct password values in KEY0-KEY7 register. This value is same as what you have programmed at password locations (PWL0-PWL7) in FLASH. Only after unlocking the device, you can perform any flash operation.

Change the boot mode to wait mode - by modifying the boot pin configuration. Using uniflash for next steps would be convenient:
1. Feed the correct password and Unlock the device - You can find this under Settings and Utilities tab
2. Now you'll be able to Erase the device.
3. Once you've erased the device - change your boot pins back to Get mode and program.

Hi,

1) In UniFlash 4.2.1 GUI, select the device and emulator that you are using.
2) Then click on start button.
3) In the new GUI window that shows up, you will notice the menu tabs.
4) Click on "Settings & Utilities". Scroll down.
5) You will see a section with "Code Security Password" title. In this section, enter the current password.
6) Then click on "Unlock".
7) Once you see the console window message that the device is unlocked, click on the "Erase Flash" button that exists above the "Code Security Password" section.
8) Now that the password is erased, you can reprogram your new password. Enter your new password in the Key fields of the "Code Security Password" section and click on "Program Password" button.

Thanks and regards,
Vamsi
