TMS320F28027: UniFlash lock of TMS320F28027 not reversable operation: Device made unprogrammable for ever

Part Number: TMS320F28027


I used UniFlash to try to lock TMS320F28027.

The procedure resulted with some error that I do not remember.

After that, I was not able to unlock the TMS with the same lock key.

Also, I was not able to use the TMS at all, so I have to go through the trouble of replacing it with the new device.

Since I am required to lock the device, please, let me know what is the step by step procedure to successfully lock and unlock TMS320F28027 device by using UniFlash tool.
