Hi Community,


We have an i.MX6DL design currently in production.  To program the eFuses in manufacturing, we use the USB Serial Downloader and U-Boot method.


For our next design, our CM would like to program the eFuses using JTAG instead of U-Boot to save time and reduce complexity for the ATE.  Is this possible?  If so, is documentation about this method available?  I can find the Fusemap, but not methods for programming it other than U-Boot.


Thank you,
