I can't build brcmfmac.ko #43

I need to build nexmon csi by myself to use customized bandwide and chennel. If I can capture with nexmon_csi_bin project, please tell me I don't need to do below task.

I tried to build brcmfmac.ko, but I got

/home/pi/nexmon/patches/bcm43455c0/7_45_189/nexmon_csi/brcmfmac_5.4.y-nexmon/chip.c:12:10: fatal error: defs.h: No such file or directory

I found brcmu_utils.h, defs.h file at nexmon_csi/brcmfmac_5.4.y-nexmon/include/ folder.

but nexmon_csi/brcmfmac_5.4.y-nexmon/Makefile dosen't include headerfiles 

ccflags-y += \
        -I$(NEXMON_ROOT)/patches/bcm43455c0/7_45_189/nexmon/brcmfmac_5.4.y-nexmon   \
        -I$(NEXMON_ROOT)/patches/bcm43455c0/7_45_189/nexmon/brcmfmac_5.4.y-nexmon/include \
        -DDEBUG

So I modified this. 

ccflags-y += \
        -I$(NEXMON_ROOT)/patches/bcm43455c0/7_45_189/nexmon_csi/brcmfmac_5.4.y-nexmon   \
        -I$(NEXMON_ROOT)/patches/bcm43455c0/7_45_189/nexmon_csi/brcmfmac_5.4.y-nexmon/include \
        -DDEBUG

I solved importing header problem, but I got another error.I guess it still have problem to build brcmfmac.ko.

It seems like source setup_env.sh wasn't run or didn't work properly for some reason.

If I can capture with nexmon_csi_bin project, please tell me I don't need to do below task.

Yup you can capture with nexmon_csi_bin :D

Check if the custom channel & bandwidth you need already work with the binaries from nexmon_csi_bin. If it doesn't, then you can look into compiling nexmon yourself.
