Basys 3 behaving differently when booted from flash.

[Tickstart]

This might be a stupid question but wth.. When I load the bitstream onto the spansion flash under the basys 3, the hardware acts differently from when programmed directly by Vivado.. I'm using block rams (ROM and RAM) and a .coe-file in my project, I presume that has something to do with it since I've never had any issues before.

What am I missing?

Hi @Tickstart,

Here is a thread where @D@n links to many different threads of programming the flash on the basys 3. If these threads do not help please post how is it different? Screen shot of the block diagram? Are you programming the flash from vivado or sdk? What version of Vivado? Screen shot of the set up for programming the flash? And can you attach a compressed folder of your project?

cheers,

Jon
