CSR1012 is being used along with a Cortex M0+ MCU and no external EEPROM neither Flash Memory. The Cortex M0+ MCU has to download the software into CSR1012 and then control it thru the UART interface (RCALLs).
Having that said, can you please help on proving an app note showing how to download the software into CSR1012 from the Host MCU (SPI Debug Interface), and whether there is a code example to make CSR1012 working with Commands received from MCU thru the UART interface (Remote Calls).
