Dear Chin Liang See,
In message 1410952049.7769.11.camel@clsee-VirtualBox.altera.com you wrote:
Hmmm... actually I can get it works well for my Altera dev kit. The get_dram_size would take in the argument PHYS_SDRAM_1_SIZE. From here, the function will ensure the memory specified can read and writable. If its failing here, probably the SDRAM access might have issue. FYI, PHYS_SDRAM_1_SIZE is 0x40000000 for 1GB.
Normally, get_dram_size() would be called with a size argument that is _larger_ (twice as big) as the biggest possible memory configuration on the respective device. Otherwise it can only detect smaller memory sizes, but would fail to detect if a bigger memory device is installed by accident.
Best regards,
Wolfgang Denk
