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.
