My question is described as follows:
My code can work well(sounds out to headphone) in hardware simulation mode(ez-kit connect to pc), but when I download the code to spi flash(ez-kit no connect to pc), then the code is not working (no sounds out to headphone).
If I place the sdram datas to internal memory(modify line 318 in ldf file), then download to spi flash again, the code can work very well.
So I suspect that sdram haves a problem, sdram can work in simulation mode, but can not work out of simulation mode, the same of code.
The attach is the code, please help me. Wait for your reply,
