BL808 :Low RAM allocations for D0 #176

Closed raspy135 closed 8 months ago

raspy135 commented 8 months ago

Board: Ox64 (BL808)

Hi I'm new to this board, I might just not know something basic, however I noticed D0 only has 64k ram in LD file. ram_memory (!rx) : ORIGIN = 0x3eff8000, LENGTH = 32K + 32K

I just pushed some ram regions and expanded ram_memory to utilize entire DRAM which is about 500k, it worked but the limitation looks like it's intended. What's the purpose of limiting ram_memory?
