Hello,
I test audio on BF537 STAMP board connected to CS42L52 codec , I2s i/f with Alsa.
Linux version 2.6.28.9-ADI-2009R1-pre.
I run:
arecord -r 8000 -f S16_LE | aplay -r 8000 -f S16_LE
After 2 minutes -20 minutes audio stops playing. Attempt to exit from test by "CNTR + C"
cause reboot of the board.
I see that after audio stopping, "SPORT TX Data" intr stops, after that "SPORT RX Data" intr stops.

Then you need to fix the CS42L52 driver.
