As the title suggests, I ran into a CCS build error saying I do not have enough memory. Is there any suggestions to fix this, can I allocate more MSRAM? Do global variables take up MSRAM or is it purely program space, because the program I wrote shouldn't hypothetically be that large but perhaps the for loops wrote out to hard coded assembly lines that make it too large.
(error message):

I will attach the program here in case you need to take a look at it for some reason. It bsically creates a "bitstream" as an array of uint32_t and writes in "binary" to it to build a compressed version of "I"
