SHARC 21369 SPI slave bootloading

Hi All,

 

           I am using SHARC21369 and will be bootloading the SHARC in SPI slave mode from a host microcontroller. Can anyone please explaing me the following

 

1)  I have seen the EE-177 (SHARC SPI Slave Booting). The example code contains code for Boot kernel and spi host. I am a bit confused as to how the boot kernel shold be loaded into the SHARC and which bookernal file needs to be loaded.

 

2) The spi host folder contains the spiloader.ldr. The boot data to be sent to the slave is contained in spiloader.ldr. I want to know how does the host ADSP-21161 loads this file into its own memory so that it can be transferred.

 

I will be grateful if anyone could explain the proceure for bootloading in SPI slave mode in detail.

 

                                             Many thanks,

                                             RAZ.
