RT1176: 5 seconds to boot

Hello,

we have a custom board that mounts RT1176 and the PMIC MPF5020. I have the boot[1:0] pins at 0, and I only burned the BT_FUSE_SEL fuse to make the boot happen from NOR QSPI.

I observe that after turning on the primary power supply (5V) the core makes the first access to QSPI after about 5 seconds.

Why all this time? Is there any other fuse to be blown due to the fact that I use PMIC?

best regards

Max

 

PS: I know there is EVKB that also mounts PMIC but unfortunately so far it is unobtainable both on the NXP website and from distributors.
