Linux with MMU on DE2-115

Hi, Though the kernel version is still 2.6.30 and ether is limited up to 100Base-T, I uploaded a demonstration example for DE2-115. http://www.alterawiki.com/wiki/linux_with_mmu_on_veek/t...

Hi,

The data path of sound system is configured as follows,

SYSTEM RAM <---> DMA <--> FIFO + I2S Interface (i2s_ctrl) <--> WM8731

so you need also the DMA driver.

Can you send me code for this driver? Or mabey driver is not needed, but only some configuration in linux files?

And unfortunately, you need several new drivers for Linux sound system. Please refer the attached files.
