We are using the iMXRT1021 and need to blow efuses via executable code.
I have looked at IMXRT1020RM.pdf, but this describes efuse functionality, but not usability. At the moment we can blow efuses either using Blhost/flashloader or MCU Boot Utility/Flashloader.
Is there an application note explaining internal efuse programming?
Can anyone advise how to do this?
I have found a reference to EFUSE_PROG_SUPPLY_GATE which I assume needs to be set, then what?
