How to prepare a rpd file

I have two projects. Boot project and Main project. Both configured as dual boot. So in the Boot project I choose the first SOF Page of the Boot project and the second SOF page of the Main project.

I burn generated POF and it works - I can switch between CFM0 (Boot) and CFM1 (Main) with BOOT_SEL pin.

Now I prepare the rpd file - in the Main project I choose both SOF Pages of the Main project and get - ''output_file_main_cfm0_auto.rpd'' and ''output_file_main_cfm1_auto.rpd''.

Now I feed the ''output_file_main_cfm0_auto.rpd'' to the Boot located in CFM0 - it burns but the Main project no good - it switches to CFM0 when I choose CFM1 with BOOT_SEL pin.

As I see in the Flash Update module

SECTOR3_START_ADDR => 16384,

SECTOR3_END_ADDR => 114687,

SECTOR4_START_ADDR => 114688,

SECTOR4_END_ADDR => 188415,

So I start at 16384 address and end at 188415 address.

I burned an rpd file and did dump back - only first 100 addresses

Looks like the same content. So I think my rpd file not good.
