Topic: please help build modificed for TDMA driver ath9k

RT-WiFi v0.1

RT-WiFi driver v0.1. RT-WiFi driver is built on top of the ath9k driver in backports driver collection. This release v0.1 is based on backports driver v3.13.2. This version of RT-WiFi driver, we implement basic TDMA features with static TDMA link schedule based on our RTSS 2013 paper. Please go through the following user guide before you use this driver.

i download source of barrier breaker and write makefile in package/rtwifi/Makefile

include $(TOPDIR)/rules.mk
include $(INCLUDE_DIR)/kernel.mk


PKG_SOURCE_URL:=(local host web server)

include $(INCLUDE_DIR)/package.mk

define KernelPackage/rtwifi
  TITLE:=A library that talks to Apple devices.

define Build/Configure


define Build/InstallDev


define KernelPackage/rtwifi/install


$(eval $(call KernelPackage,rtwifi))

and compille with

make package/rtwifi/install V=s

but building stop with error

Error: -march=mips32r2 is not compatible with the selected ABI
/home/botto/openwrt/build_dir/target-mips_34kc_uClibc- error: '-march=mips32r2' is not compatible with the selected ABI
 #include <linux/module.h>

please help compilling this package sources and user guide can download from cs@utexas@edu/users/cps/rt-wifi@html
how to change arch easy or this release code oriented writed for x86-64 arch?

Oh, it's good to support TDMA. But where i can get the source package?

I think the following should enable ath10k but I get only a Kernel Oops on TP-Link with supposedly "rare" AR1A hardware

1. enable ath10k
in your trunk folder there is package/kernel/mac80211/Makefile

Patch it with the ath10k enable patch from the mailing list:

2. update mac80211 (compat-wireless) to backports (same project new name)

PKG_SOURCE_URL:=(URL kernel org)/pub/linux/kernel/projects/backports/2013/08/02


and a line with "echo" in Build/prepare to the new name (backports instead of compat)

3. refresh patches of mac80211

make prepare
make package/kernel/mac80211/prepare V=s QUILT=1
cd build_dir/target .../linux.../backports-20130802/
quilt series
# delete 2 large pending work patches - less fixes for other wireless drivers 
# but you want to test ath10k anyway
quilt delete 300- ...

# repeat / use following 3 commands until all patches are working or 
# delete some patches for drivers not used in your image
quilt push
quilt refresh
# remove an applied patch
quilt pop

4. maybe integrate hw revision test
patch from ath10k mailing list:

# if you are at the end of quilt series - name patch f. ex. 900-ath10k_hw_id.patch
quilt import <path>/900-ath10k_hw_id.patch
# patch is in patches dir
quilt push
quilt refresh

5. update packages: atm you only have a modified build_dir

# in openwrt buildroot
make package/kernel/mac80211/update

After that you should build your image.
atm you have to manually load the kernel modules (insmod ath10k_core, insmod ath10k_pci )

i begin doing all my modification with backport 3.13.2 with help this tutorial.
but i get last error /net/wireless/cfg80211.ko is missing

Re: please help build modificed for TDMA driver ath9k

today i cross compile the backport-3.12.8-1 with the help this tutorial "wiki@openwrt@org/doc/devel/crosscompile"
sudo make CC=~/openwrtOLD/staging_dir/toolchain-mips_34kc_gcc-4.8-linaro_uClibc- LD=~/openwrtOLD/staging_dir/toolchain-mips_34kc_gcc-4.8-linaro_uClibc- ARCH=mips
and replace /usr/src/linux-headers-generic_3.3.3 with  build_dir/target.../linux-ar7xxx_generic/linux-3.x.x
when compilling running i see warning "mips-openwrt-linux-uclibc-gcc: warning: environment variable 'STAGING_DIR' not defined"  lots of.
but i right exporting this STAGIND_DIR with right path. and see echo $STAGING_DIR path to toolchain dir.

when make the finish and i get the files:

I replace this files with files located /lib/modules/3.x.x/ in router.
After reboot wifi not work.
in logread i see "PHY for wifi device radio0 not found"
and i cd /sys/class/ieee80211/
but this folder has been a empty....................

after this i using patchs from packege/kernel/mac80211 on backports. and deleting failed patchs.
no result all the same

Re: please help build modificed for TDMA driver ath9k

What a pity. It failed to run on openwrt.
