BF547 Boots from UART Host

I am planning to boot the BF547 from a UART host (an ARM9 CPU) and I have some questions:


1. When the DSP performs the autobaud sequence, does it change the EDBO bit as well or is this bit fixed?


2.  Can we disable the autobaud sequence and use a fixed baud instead?


3. How does host processor know when the firmware download is completed?


4. How does host processor know the downloaded blackfin firmware is corrupted?  How does it recover?
