Boot Mode iMX6UL

Hello,

If the Fuses are set to boot from NAND and BOOT_MODE set to 00 with resistors - is it possible to change the BOOT_MODE to 01 via resistors even if the Fuses and programmed.

If yes, isn't this a security issue where in someone can change the boot mode, and boot from for eg. SD Card and read all the data from NAND. 

Is there a way to prevent changing the Boot Mode once the Fuses have been programmed?

Thank you

Regards

Santhosh

Hi Santhosh

If BT_FUSE_SEL = 1, all boot options are controlled by the eFUSEs, so it

is not possible to change boot mode.
