[bitbake-devel] Integration of FMAC(Orga) Driver into Yocto Environment - regarding

[Jameel Valai Kareem]

Hello Everyone,
 I am  currently working on the creation of new MACHINE type for addressing the Cypress Broadcom FMAC driver release<https://community.cypress.com/docs/DOC-14056> ( attached for your reference).
As part of the initial steps, I am ensuring that, we have necessary recipes tested, so that, it can added to the new MACHINE type along with the new layer "meta-murata-wireless"
I was able to get the wpa-supplicant and hostapd recipe into the Yocto setup.

I need your help in resolving a problem related to native make when using the Backport Tools.

Backport Tools:

FMAC driver uses Backport Tool (v4.12-backports) to generate the necessary .ko files, namely (compat.ko, brcmfmac.ko, brcmutil.ko and cfg80211.ko)

In the Readme file, 2nd step under the Section : "Build the cypress driver/backports modules" is to

-        (Native) compile local tools and generate .config without sourcing Yocto tool chain settings.

make KLIB=$MY_KERNEL KLIB_BUILD=$MY_KERNEL defconfig-brcmfmac

Problem Description:


I don't know how to use the native make in the do_compile( ) function in backportcypress_1.0.bb ( attached for your reference), as Yocto uses tool chain settings.
              I get the following error message, when I compile backportcypress_1.0.bb recipe.

Could you please let me know how to generate the .config file by using native make, instead of oe_runmake in Yocto setup?.
