How to set "Boot_Device_Selection" bit-field by MCUXpresso Secure Provisioning via UART mode

[thanhnambka]

Hi all,

I'm working on board using MIMXRT1052DVL6B.

I was set BOOT_MODE[1:0] = 0b01, and then set "Boot_Device_Selection" = 0b1111. And now, i want to set "Boot_Device_Selection" = 0b0000 then error occurs: 

I'm using MCUXpresso Secure Provisioning v4.0.1

My question: How to set "Boot_Device_Selection" = 0b0000.

Hello

Apparently, you´re trying to burn a fuse that was burned previously.
It is important to understand that fuses can only be written once. Once you write a value to that field it cannot be reversed.
I apologize for the inconvenience this may cause you.

If you have more questions do not hesitate to ask me.
Best regards,
Omar

Thanks you for your reply. That is so sad for my problem!

However, It doesn't seem to be mentioned in the IMXRT1050RM that fuses can only written once.
