Yes. It’s step 5
- turn the PBP on
- wait 2 seconds
- turn the emmc switch on the board
what happens is this:
- you turn the PBP on
- uboot loads, only sees an sd card (because the emmc is still off) and boots from the sd card
- there is a tiny pause after uboot load and before the kernel starts, this pause is what you are aiming for.
- you flip the emmc switch in the decisive moment and the emmc is on instantly
- the short break is over and the kernel starts and hurray sees the emmc active
- the system boots with emmc active and now a new image can be flashed to the emmc, everyone happy..
- turn the PBP on
- wait 2 seconds
- turn the emmc switch on the board
