[Yocto] [Broadcom 4375 PCIE] [i.mx8mm] Build synaptics 4375 driver with Yocto image failed

Board: Myir i.mx8mm

I would like to package synaptics version of 4375 wifi driver with Yocto image.

If build this PCIE or SDIO version driver via "SDK", it is fine for finished & create .ko file
But if build this PCIE version driver via Yocto process(bitbake), Yocto would show error about " In function 'dhdpcie_bus_register': <command-line>: error: expected ')' before 'pcie'".

Build this SDIO version driver via Yocto process(bitbake), it is normal to finish to create .ko file.

From the following info, this error could expansion of macro failed. However, I didn't modify dhd_pcie_linux.c & pci.h code.

Detail Yocto build log for this is as log.do_compile.18399.log.

And Broadcom 4375 driver Makefile (Makefile.log => Makefile). It is adjusted by customer.

Adjust LINUXDIR to Linux kernel builder path.
Build pcie : make bcmdhd_pcie
Build sdio : make bcmdhd_sdio

Do someone touch this similar problem? Thanks.

could you share the detailed build steps with me?

Dear Joanxie,

Thank you for your respond

I just found customer Makefile issue (I have already got trouble with this issue about two weeks)

In this driver, I shouldn't set CONFIG_BCMDHD_MULTIPLE_DRIVER=Y to create different naming .ko for PCIE / SDIO at the same time, and it would cause this kind of error. Maybe DHDFLAGS settings becomes wrong after that.

Besides, I found the other method.

1. Set CONFIG_BCMDHD_MULTIPLE_DRIVER as None

2. Build SDIO version then rename .ko

3. Build PCIE version.

Finally, thank you for help^^
