Pinout Change History

V1.3 pinout changes from V1.2/V1.1:

  • Pin92 on J69 was NC on V1.1/V1.2 now connects to PMIC_SLEEP_H on V1.3 for external CPU status
  • Split one 4-lanes MIPI CSI to two 2-lanes MIPI CSI: move MIPI_CSI_RX_D3N/P, MIPI_CSI_RX_D4N/P from Pin133/135, Pin139/141 on V1.1/V1.2 to Pin128/130, Pin 134/136 on V1.3
