Hi

I am trying out the CYW43439 on imx7 and imx28 platforms. I have tried to use the latest driver I could find (5.4.18) and built it on 4.4.187 and 4.9.11 kernels respectively, using backports.

However when I start linux the devices are not detected and the following kernel error is present in the logs:

brcmfmac: brcmf_fw_alloc_request: Unknown chip BCM43439/5

Is the device not supported by the driver? And if not, how am I able to use the device?

Hi,

The current FMAC release does not support 43439 and I'm checking internally for the driver. Can I know your sales point of contact?

Thanks

I am not too fond of putting that information where it is publicly available. Is it possible for me to forward your contact information to him instead?

Hi,

CYW43439 is not a mass marketing chip. So, I would recommend you to contact the sales again for the right support.

Thanks
