9.5.4. Connecting SE050 Arduino shield to imxRT1050¶
SDA an SCL are connected differently for RT1050 as compared to FRDM-K64F
ARD_SDA is Required on pin 5 of SE050 Arduino Shield
ARD_SCL is Required on pin 6 of SE050 Arduino Shield
Connect SE050 to imxRT1050 Arduino stackable headers and change jumper J14 as:
This connects SE_VDD directly to 3V3 and bypasses enable signal. This is required because enable pin on imxRT1050 coincides with RC-663 nRST pin so we cannot use SE_EN signal to drive SE_VDD.
9.5.4.1. Jumper Settings for SE050 Arduino Shield and 1050RT¶
SDA J15 Pin 1 & 2 connected using jumper
SCL J17 Pin 1 & 2 connected using jumper

Note
in a new MIMXRT1050 Board, Resistors R278, R279, R280, R281 are DNP. So they either have to be shorted or a 0 OHM resistor has to be populated.
