Reload BOOT_MODE from UBoot

I am using Uboot on an i.MX6UL. I'm flashing UBoot from the "serial downloader" mode (BOOT_MODE = 01). Once the flashing is finished, I would like to reset the CPU in order to boot properly from the eMMC. The problem is, when I type the reset command from Uboot, the BOOT_MODE bits from SRC_SBMR2 are still 01 even if the BOOT_MODE pins are 10. Thus, the CPU boot a second time in "serial downloader" configuration instead of "internal boot".


I was wondering if forcing a new latch on BOOT_MODE pin was possible. If yes, how to do it?


Thanking you by advance.
