My customer is facing the issue that i.MX6SX cannot boot from eMMAC with fast boot mode on their board.
When they configured BOOT_CFG1 to ON(1), the boot from eMMC stopped.
And when BOOT_CFG1 is unset, the boot from eMMC can be achieved.
The similar behavior is seen as an actual phenomenon on the other community threads as below, though target chip discussed in those threads is not i.MX6SL.
On the other hand, in the following thread it is said that BOOT_CFG1 should be set for eMMC fast boot of i.MX6SL.
Could you show me which is the correct (BOOT_CFG1 should be ON or OFF) for eMMC Fast boot from i.MX6SL?
