OMAPL138 & RS9113 in USB

Other Parts Discussed in Thread: OMAP-L138, OMAPL138

Hi,

In my custom board I have Redpine RS9113 WLAN/BT/ZB -module connected to USB0. 

Linux used is mcsdk_1_01_00_02 linux-3.3-psp03.22.00.06.sdk, file system is based on tisdk-rootfs-image-omapl138-lcdk.tar.gz

I found thread:

https://e2e.ti.com/support/wireless_connectivity/wilink_wifi_bluetooth/f/307/p/35423/708113#708113 

Which forwarded to wikis:

1) http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_OpenSource_am335x-evm_R5_00_18_WLAN_build#WLAN_components

2) processors.wiki.ti.com/.../OMAP_WLAN_build_instructions_on_any_SDK

I've successfully compiled and installed rs9113 -related SW to Ubuntu (12.04) after loading libnl. Redpine instructions say about Makefile tuning: "The DEF_KERNEL_DIR variable has to be assigned the path of the compiled kernel path. For an x86 based Linux platform, this path is usually “/lib/modules/<kernel_version>/build” and this is the path assigned in the Makefile provided in the package". 

DEF_KERNEL_DIR := /lib/modules/3.13.0-32-generic/build  works for Ubuntu.

So I would like to ask:

1) Are wikis 1 and 2 valid for OMAP-L138 and mcsdk?

2) In Wiki 2 you recommend " Please, consult release notes for the board you are working with where the kernel patches can be downloaded" - could you forward me to source to download ones for  l138 LCDK -compatible HW.

3) Where should this DEF_KERNEL_DIR point when cross-compiling?

4) Any easier methods to realize this all?

  • This is the linux kernel directory for OMAPL138 LCDK board.
    ~ti\mcsdk_1_01_00_02\board-support\linux-3.3-psp03.22.00.06.sdk

    Ex:
    DEF_KERNEL_DIR=/opt/ti/mcsdk_1_01_00_02\board-support\linux-3.3-psp03.22.00.06.sdk

    before building the WLAN driver, you have to compile the kernel for OMAPL138 LCDK board.

    ~ti\mcsdk_1_01_00_02\board-support\linux-3.3-psp03.22.00.06.sdk\arch\arm\configs\da850_lcdk_defconfig

    If you are not able to find the WLAN driver then you can add it.

    Please let me know if any problem.
