Hi There, 
 The firmware for the DA14531 SoC is stored in the flash of the DA16200. To do so, the DA14531 firmware should be written directly to the flash of DA16200 via the SWD interface. 
 When the DA16200 wakes up, it copies the BLE firmware from flash to RAM of DA14531. So, the System-RAM of the DA14531 should be empty, as the DA16200 will copy the BLE firmware into it. 
 The BLE FW (in the flash of DA16200) can be updated or changed anytime. 
 Please check table 6 & table 7 in um-wi-056 : https://www.renesas.com/us/en/document/qsg/um-wi-056-da16200-da16600-freertos-getting-started-guide?language=en&r=1599971
