Custom board iMX6S - Issue with WiFi module LBEH5DU1BW

Hi all

We are encountering an issue with our custom board using iMX6S CPU and Murata's WiFi module LBEH5DU1BW (chipset BCM43340/CYW43340). 

Problem reported "SDIO interface hanged and SW driver stuck while waiting for the response from WiFi module". This problem happened after 3 months running smoothly in the field.

Any idea what we should look into in order to find out the root cause? 

Thank you all.
