Marvell Wi-Fi chip not powering up sometimes, need a power cycle to fix it.

When not working can see the below kernel logs:

[ 33.761628] wifi_pwrdn_fake_regulator: disabling
[ 33.766796] pcie_switch: disabling

When working can see the below kernel logs:

[ 6.890983] mwifiex_pcie 0000:01:00.0: enabling device (0000 -> 0002)

Using Apalis IMX8QM SOM with kernel version 5.4.77-5.1.0.

 

Is there any fix for this issue? Thanks in advance.

Hi @abrafo78777!

Thank you for contacting NXP Support!

 

Are you using a custom base board?

The wifi that you want to use is that the SOM has or are you installing other wifi module?

 

What BSP version are you using?

 

Best Regards!
