Summary: test fail on bf537-stamp with suspend to ram mode in ad1836 power testing

Details:

test fail on bf537-stamp with suspend to ram mode in ad1836 power testing.

when test "Rvrec -w -S -b 16 -s 48000 -t 5|vplay", it show "NULL pointer access"

And this test with "standby" mode on bf537-stamp is ok and "ram" mode on bf533-stamp is also ok.

the log as follow.

I can't repeat this problem in lastest svn trunk.

By the way, if there is error like this:

root:/> arecord -t wav -c 2 -f S16_LE -r 48000 -d 5 |aplay

arecord: can't resolve symbol '___snd_pcm_hw_params_{et_period_size_last'

aplay: can't resolve symbol '___snd_pcm_hw_params_{et_period_size_last'

root:/>

Don't forget add a pull down resistor to SCKE.

Refer Bug[#5370]:

I test it again and now the case is pass.

I closed it.
