SDMMC Adapter Configuration

Introduction

This page will instruct you on how to connect different EM boards with the SDMMC adapter
Note: This configurations are for debug connection only i.e HCi Tester/Logger only.

SDMMC Configuration

• Order the SDMMC
  
• The board comes with default jumper configuration: SDMMC User Guide
  
• The following changes need to be done in order to operate in debug mode:
  

1. Remove J6 and close J20.
   
2. Change the 4 jumpers for UART to be 2-3 instead of default 1-2 ( J7,J8,J10,J11).
   
3. Change J9 and J12 to be 1-2 position instead of 2-3 to drive enable lines to the chip.
   

Host processor configuration

To control the SDMMC board with a host processor and the provided jumpers, use the following configurations:

1. Remove J6 and close J20.
   
2. Use the following table as a guide:

Description	SDMMC Connection Point	Jumper Color	Host connection
HCI_TX_LS	J8, pin 2	Yellow	Connect to TX line
HCI_RX_LS	J9, pin 2	Yellow	Connect to RX line
HCI_RTS_LS	J10, pin 2	Yellow	Connect to RTS line
HCI_CTS_LS	J11, pin 2	Yellow	Connect to CTS line
BT_EN_COM (1.8V MAX)	J9, pin 2	Blue	GPIO, active high
WLAN_EN_COM (1.8V MAX)	J12, pin 2	Green	GPIO, active high
HOST_WL_IRQ_3V3	J19, pin 1	White	GPIO, active high
GPIO9 (1.8V MAX)	J19, pin 3	White	GPIO
GPIO11 (1.8V MAX)	J19, pin 4	White	GPIO
GPIO12 (1.8V MAX)	J19, pin 5	White	GPIO
GPIO10 (1.8V MAX)	J19, pin 6	White	GPIO
PCM_IN_LS	J16, pin 1	Purple	PCM Out
PCM_OUT_LS	J15, pin 1	Purple	PCM In
PCM_FSYNC_LS	J17, pin 1	Purple	PCM FSYNC
PCM_CLK_LS	J18, pin 1	White	PCM Clock
GND	J19, pin 2	Black	Ground

CC256X Configuration

For the CC2564MODNEM or CC2564C QFN boards

• On the EM board perform the following steps in order to connect it to the SDMMC board.
  

1. Desolder the headers RF1 and RF2
2. Desolder the regulators U2, U3, and U4
3. Short resistor R2 for the QFN-EM board

Note: On the CC2564MODNEM board – Remove J4 jumper, and connect J3 (Changing VBAT_MCU to VBAT_EDGE).
