FreeRTOS, SVC Handler and Buttonless DFU

Question

I am trying to get the application to enter DFU via the buttonless DFU service using SDK 15.2. It appears to be stuck because of an SVC call not returning. Both application and bootloader have NRF_DFU_BLE_REQUIRES_BONDS set to 1. Initially it hung at the call to nrf_dfu_set_peer_data() in ble_dfu_bonded.c. On looking at documentation from a previous SDK, it looks like I have to call ble_dfu_buttonless_async_svci_init(); before ble_dfu_buttonless_init(). So I did and now, it hangs at nrf_dfu_set_peer_data_init(). 
 I am using FreeRTOS. Could it have to do with the SVC handler in port.c being different from the one in nrf_svc_handler.c?

Because the boot loader is part of the SVC chain, you'd need to retain that functionality as part of the SVC handler if using FreeRTOS in the boot loader. So port.c would need to be modified to replicate the functionality from Nordic's boot loader. 
 Personally, I think modifying the boot loader to be based on FreeRTOS would be a big undertaking and not worth the effort unless its functionality had to be significantly extended.
