Hi @ssampath ,

Use Multiboot concept by referring this XAPP1257.

Use external trigger ( like push button) which acts as trigger, which is responsible for loading BIT Files (which you wish) from flash. To achieve use this you need to use ICAP Primitive.

For example : Initially 1st Bit File will load from Nth address of flash to FPGA. And you continue to use that for a while and then when you again press External Pushbutton present on board, it will load another Bit File.

Refer ML605 multiboot steps  and Design files which uses above method.
