ADSP-21573 Second-stage bootloader

I used the adsp-sc5xx_ez-kit evaluation board to verify that the second-stage loader function,and it can work properly.

I referred to the demo( in the url. ADSP-SC572 Second stage loader won't boot main app with ad-_rom_boot()

However, our product uses the ADSP-21573, so I transplanted the code from the SC573_SSL project to the ADSP-21573 project and it did not work properly.

Could you please provide SSL project for adsp-21573?



  • Hi Kevin,

    Unfortunately I do not have an SSL example for ADSP-21573. However, you can simply modify the existing ADSP-SC573 project to ADSP-21573. I would suggest you to refer the below Application note for more details.

    Having said this, I would also suggest you to confirm that normal SPI Master booting is working properly on your custom board. You can initially start with a simple LED code and once the working is confirmed you can proceed booting your application. I would also suggest you to check the cache configurations and enable/disable it accordingly. You can navigate as follows.
    Project-> system.svc->Startup Code/LDF/Cache Configurations

    Please let me know how you get through.

  • This problem was resolved when I disabled the cache, thank you very much.
