Hi everyone,

  i have a strange problem with my a20 lime2 board as described in the topic. Please help

 

The i2s0 pins should be MCLK-PB5 BCLK-PB6  LRCK-PB7 DO0-PB8. 

  But I got data signal from PB7, and the LRCK was missing.

 

a 24 bit  44.1khz  file was played by aplay.

both i2s_do0 and sata_pwr_en use PB8. Everything is ok, when i use PC3 as sata_pwr_en.
