I'm using the ADSP-BF533 EZ-KIT REV1.6. The c code was transplanted and uses a lot of dynamic allocation. For convience I set the system stack in the SDRAM using the Project Option dialog of VDSP++. However , whenever I set the system stack and system heap more than 4MB(including 4MB,but 3MB works), building the project always ends with errors. The board has 4 banks of SDRAM with 8MB size each. Why large system stack doesn't work and how to fully use the SDRAM memory. I'm gratefully seeking help.
