pcie wifi card ath10k

Hy Ladies and Gentlemen,

For my project, i use a Solidrun Clearfog base.
Os is build with Buildroot.
The Kernel is custom too.

I have a wifi card pcie : driver ath10k and firmwre QCA988X.

When i switch on the Clearfog, the wifi card doesn't mount :

Code:dmesg | grep 'ath'
