Erasing MCU after enabling secure boot in LPC55S16

[nxf64834]

Hi all,

Can we mass erase the chip using blhost after enabling secure boot in LPC55S16 ?

If no, then the chip will get scrapped if incorrect data is programmed?

Is there any document with list of commands that are allowed in blhost after enabling secure boot?

Hello,

If you want to change configuration, you can program the empty CMPA into chip.

Recommend have a look at:
