Issue with interfacing WiFi/BT Laird Sterling Module

econote_vikrant — Mon, 05 Aug 2019 16:07:24 GMT

Greetings!

I am trying to interfacing Laird's Sterling LWB module for the last 3 weeks with imx7dsabresd.

I have solved issues one after one, but now only the big issue is with me is that one of the modules is automatically getting uploaded in the kernel log, however, I have modified device tree also to debug from where this module is getting uploaded but no help from debugging. Can anyone suggest to me what's going wrong?

Following is my Kernel log as well as the status of 'lsmod'

Kindly check and help for the same

Hi Vikrant

"brcmfmac: Unknown symbol" may mean that improper driver was used or

firmware. One can check Cypress Linux WiFi Driver Release (FMAC) [2018-... | Cypress Developer Community

and post issue on that community.

Best regards
igor
