Hi,
We gonna choose a module that uses CYW43438 chipsets and I searched all over the related websites but cannot found any FMAC driver for 5.10, however the kernel 5.10 builtin the bcm43x FMAC driver, but I'm not sure if the bcm43438 was supported.
Thanks,
Benny

We have FMAC driver releases available here https://www.cypress.com/documentation/software-and-drivers-archive/wifi-bt-linux-archive but they have been tested only up to v5.4.18. However, CYW43438 is supported in the driver release. The latest is cypress-fmac-v5.4.18-2021_0114.zip.

We are also trying to make it work for linux kernel 5.10. So far it does not work out of the box: the error we get at startup:
brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50
and when we try to start manually the wifi module:
modprobe -r brcmfmac
we get the following errors:
brcmf_chip_recognition: chip backplane type 15 is not supported
brcmfmac: brcmf_chip_recognition: chip backplane type 15 is not supported
[ 1368.550960] brcmfmac: brcmf_sdio_probe_attach: brcmf_chip_attach failed!
[ 1368.551026] brcmfmac: brcmf_sdio_probe: brcmf_sdio_probe_attach failed
[ 1368.570586] brcmfmac: brcmf_ops_sdio_probe: F2 error, probe failed -19...
@Benny_koo: did you find a way to make it work with kernel 5.10 ?
@GauravS_31: do you have documentation explaining how we can test the FMAC driver release for a kernel 5.10 ?

We do not have any documentation to support kernel version higher than the currently supported version 5.4.18. However, in the next release, support will be added for 5.10.
