WL1835MOD Cape script not working for BeagleBone Black with Debian

Hi,

Can you try setting "KERNEL_PATH=DEFAULT" in the setup-env?
I think the patch set is specific for am33x-v3.8 branch.

Regards,
Gigi Joseph.

Iain,

Thanks for updating the process so quickly. After 2 days of trying to get the kernel built, I am again at a standstill.

The first problem is that to re-build the kernel requires > 3.2 GB to clone the linux kernel and apply patches so that slowed me down a lot. To overcome that, I am booting the BeagleBone from eMMC and formatted a blank uSD card to create my build directory upon. That allowed the kernel to be cloned and then it successfully applied all patches.

The showstopper is then building the kernel. When attempting to perform

     make -d ARCH=arm CROSS_COMPILE=" " menuconfig

the following errors are returned:

HOSTCC scripts/basic/fixdep
scripts/basic/fixdep.c:106:23: fatal error: sys/types.h: No such file or directory
compilation terminated.
make[1]: *** [scripts/basic/fixdep] Error 1
make: *** [scripts_basic] Error 2
kernel_version:
cp: cannot stat `bb-kernel/deploy/.zImage': No such file or directory

I cannot figure out why the make is not picking up where the kernel's include files are stored. Further debug on the make menuconfig returns (truncated to tail end of the debug info):

Any ideas how to get the make to properly use the correct include directories?

BTW, I am using the stock Debian on the BeagleBone Board (Linux beaglebone 3.8.13-bone47 #1 SMP Fri Apr 11 01:36:09 UTC 2014 armv7l GNU/Linux)

Hi Michael,

I have only developed the script to CROSS_COMPILE on a Linux Host so I'm sorry I can't help you with any ideas for a native compile. I will change wiki to reflect this restriction.

Iain

OK, I finally got the Debian kernel built! For reference, I am cross-compiling on a Kubuntu 14.04 release running inside of an Oracle VM.

I had to make the following updates/modifications:
1) apt-get install autoconf
2) apt-get install libtool
3) apt-get install pkg-config
4) apt-get install python-m2crypto
5) Change LDLIBS inside of src/crda/Makefile to add -lcrypto before the -ldl
6) remove reference to rint in src/libnl/lib/utils.c (line 80)
7) Correct the verify_skeleton function inside of build_wl8xx.sh script as there needed to be an extra space between "LSB executable" for checking the ELF 32-bit files to not produce ERRORs.

There were still some patch errors and compiling warnings afterwards but the image is able to be created and I programmed it onto an uSD card. The image did boot up on the BBB. I will have to do more testing to check the operation of the WL1835MOD cape operation.

Michael

Joseph,

I changed the KERNEL_PATH is setup_env and re-ran the new script that Iain had created and my BBB is now booting with the WL1835MOD cape operational. Thanks for the tip.

Michael
