Where can I get the C5509A bootloader source code?

Hi,

Currently I am debugging the C5509A image downloading process thru McBSP and met some difficulties that sometimes there is no response from the DSP bootloader or sometimes the response is not as expected. It is hard to find the root cause since I do not know how the DSP bootloader behaves. Where can I get the bootloader source code? It will help my debugging process a lot.

Thank you very much!

    Hi William

    We do not share the boot loader source code externally. Our hope is that the boot loader application note will be enough for your development and debug.

    Hi Mukul,

    OK, :(.

    In fact, I have made some progress that the boot table has been downloaded successfully to DSP( I checked the waveform with the boot table, they are exactly the same) and the IO4 also would be set high then, but the DSP could not branch to the entry point, the phenomenon is that the DSP seems to reset for it re-sent the READ command (0x03) and address (0x00) again after about 6s. Of course, the reset is not performed by my firmware since the RESET pin is always high which is controlled by my firmware.

    What is the possible reason that DSP could not branch to the entry point address and reset itself? Do you have any suggestion on it?

    Best regards!
