Running code from SDRAM or QSPI

Hi all,

I am currently planning a rather complex synth build based on the daisy seed and I’m pretty sure that the internal flash will not cut it in terms of size.

Has anyone of you tried running code from SDRAM or QSPI with the custom daisy bootloader and can report on the experience?

How big is the actual performance penalty for using the latter?

Many thanks in advance!
