yes, maybe flashing through a programmer may take same time, however you can do it in parallel ... e.g. when they are manufacturing, they can also be flashing the parts at the same time .. once the board is manufactured it may be much faster for you to make a product from it (you do not have to flash it, just test the peripherals).
PS: also, I think NXP may be able to set the fuses, or not (I may be wrong, maybe it was a different chip)?
nachodizz990 Depends on how many boards you have to commission simultaneously ! I remember reading mfgtool supports multiple boards u-booting through OTG. If yes you can write a bootscript which can be run from an SD card to automate fuse burning process and even to burn emmc using gzwrite utility in u-boot (the OS image should be in .gz format inside the boot partition of SD). Since this has to be done individually from each u-boot terminal, to commission 10 boards simultaneously you might need 10 SD card though !!!
Dear Robert, yes, eMMC can be pre-flashed (Good Idea) but, anyway we have a Bottleneck because we need to run MFGTOOL´s UBOOT in order to blow efuses
I have good news, the DIP switch to select to enter in Serial downloader [01] is not necessary to be fitted because the SoC when is crude will enter by default in Serial Downloader mode
The Dip Switch is expensive at large scale ...

nachodizz990, we do not do it in our office, but I believe VOIPAC (they manufacture our boards), they flash/burn everything by themselves during testing. I do not think they have some special methods for it, but I am not sure how many boards they sell every month. If you need to produce 20k in short time, then it may be challenging.
However, maybe eMMC may be flashed before assembly?
