Facing Issue with QCA9984 WiFi module

Hi,

I am facing the issue with QCA9984 WiFi module. "https://www.compex.com.sg/product/WLE1216V5-20/"

I am using LED 17.0.1 and linux 4-4.53 version on NXP LS1043ARGW board.
While probing the device my board hangs and start rebooting. below are the logs:

I tried to change almost all available firmware files on the git repository but that does not help.
Can any one help me into this issue .

Did u find any solution for this issue? I am also facing this issue in QCA9984 with the ath10k driver.

I resolved this issue. You will have to load correct firmware file.
I am using compex WiFi module and firmware is available on https://wiki.compex.com.sg/wiki/Ath10k_Compatibility

Hope this will help you. if it does not help then share the logs.

Sunil
