which SDK is compatible with S120 v2 ?

Question

Hello, 
 I am trying to use the s120\multilink_central example, using SDK v6.1 and S120 v2.0. The probleme is that I get a hardfault handler. I think that the probleme is due to incompatibility between SDK and S120. 
 I indicate that in the nordic web site, it's mentioned that SDK v6.1 supports only S120 v0.8, which I could not find it. 
 Any suggestion please !

I have not tested S120 v2.0.0 with SDK 6.1.0, however, below are my suggestions on what you could try: 
 What could result in a hard fault, is if the IRAM1 address is not correctly set in Keil, see this post. 
 In addition, since the S120 v2.0.0 supports non-concurrent central and master, the role of your device should be set during stack initialization. It can for example be done the following way (tested in SDK 7.2.0 only..): 
 static void ble_stack_central_init(void)
 {
 uint32_t err_code;

 ble_enable_params_t ble_enable_params;

 ble_enable_params.gap_enable_params.role = BLE_GAP_ROLE_CENTRAL;
 ble_enable_params.gatts_enable_params.service_changed = IS_SRVC_CHANGED_CHARACT_PRESENT;

 // Initialize the SoftDevice handler module.
 SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, false);

 err_code = sd_ble_enable(&ble_enable_params);
 APP_ERROR_CHECK(err_code);

 // Register with the SoftDevice handler module for BLE events.
 err_code = softdevice_ble_evt_handler_set(ble_evt_dispatch);
 APP_ERROR_CHECK(err_code);

 // Register with the SoftDevice handler module for System events.
 err_code = softdevice_sys_evt_handler_set(sys_evt_dispatch);
 APP_ERROR_CHECK(err_code);
}
 
 Also remember to change the header files for S120 that your project links to, to the header files for S120 v 2.0.0, in the following folder: C:\Keil\ARM\Device\Nordic
rf51822\Include\s120 
 If using SDK 7.2.0, the new header files should be placed in the following folder: C:\Keil\ARM\Device\Nordic
RF51_SDK_7.2.0\components\softdevice\s120\headers

which SDK is compatible with S120 v2 ?
