Hi,

IMXRT1021 boot informations are provided in section 8.1 and page 287 of the referance manual. (IMXRT1020RM.pdf)

 

Peripheral    Instance    Port(IO function)     PAD                                Mode
LPUART         1             LPUART1_TX         GPIO_AD_B0_12           ALT2
                                      LPUART1_RX         GPIO_AD_B0_13           ALT2

 

But, LPUART1 peripheral is not found in the defined pads.

We ask for help with the correct pads for the LPUART1 peripheral for boot the device.
