Custom board iMX6S - Issue with WiFi module LBEH5DU1BW

[haidoan]

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.

Hi Hai

if this is just one board one can change wifi module

with working board, to find root cause.

Best regards
