SHARC 21479 SPI boot

Hi ,

 

On EZ-KIT 21479 setting the boot mode switch position 1  will make Master boot where sharc is master .

 

And with regards to loader file select SPI flash which is similar to SPI slave which doesnt have 0xA5 word at the start .

 

Figure 6-1. in http://www.analog.com/static/imported-files/software_manuals/50_ldr_mn_rev_2.5.pdf states that 0xA5 is needed for Master Boot .

 

If we set to SPI Master when creating LDR we are unable to boot , we are able to boot when we create LDR using SPI slave or SPI flash .

 

Could you please let me know with regards to this .

 

Thanking you
