Yes. I will try to use other module to verify again.
And I forgot some important to tell. First time I use
iMX31 SD interface connect to 88w8686 and I get a
error(-84) at first 60 byte of  helper firmware
download procedure . And I change the default setting
of SD interface of iMX31. I disable 4-BIT capacity of
SD interface. And The helper download success but get
other error at first transaction of firmware download.
Maybe the error related to 4bit or 1bit of io
