Summary: On BF537-STAMP with AD1836, it fails to record wav audio with particular settings by alsa lib tool

Details:

On BF537-STAMP with AD1836, using alsa lib tool to record a wav stereo audio with 8k sample rate and U8 format, it will fail. Recording with other format and sample rate is OK. Config file is attached.

It can be seen from the log that arecord crashs in libasound.so,

reason is :Data access misaligned address violation

- Attempted misaligned data memory or data cache access.

but there is no such problem on AD1981.I modified the driver to let AD1836 run

on 16 bit mode as AD1981,no crash any more.

--- Cliff Cai 2008-02-01 03:24:56

use fixed period number to avoid memory address misaligned.

--- Vivi Li 2008-02-18 05:04:40

OK. Close it. Thanks!
