Could malloc/calloc get memory from SDRAM, while main program loads from BRAM?.

Yes It works fine, I've used it several times, just dispatch things in the linker script. But be we have a problem, when we reset the firmware, heap gets full and heap initialization get false as the heap pointer reaches memory upper limit. For now we can't get the to reset the heap pointer, so if you have a solution please let me know !

How do you configure the linker script?. Only stack and heap for the sdram and the rest of the parameters to the bram?

Thanks

If I configure Heap and Stack for SDRAM in linker script, the program doesn't run.

Just start with the heap in the sdram, experiment with a little firmware for test.

Xilinx doesn't allow to place heap and stack in separate memories. So I have to place both in Sdram. Any test run with this configuration in my Spartan 3E starter kit.
