1 The burst clock runs whenever ACLK is active (independent of chip select configuration)

 

I tried activating the BCLK continuously on my i.MX6Q board by setting ('1') the BCM bit (bit 0) on the EIM_WCR (0x021B_8090h) register.

I am not getting any clock on BLCK - constant '0'.

Did I forget anything?

here is my register configuration

MX6Q_PAD_EIM_BCLK__WEIM_WEIM_BCLK,  //pin_conf

writel(0x00020081, ram_reg);       //EIM_CS0GCR1 

writel(0x00000001, ram_reg + 0x90);  // EIM_WCR

someone help me ,what should i do to solve this problem??
