Hello,

Have an issue to generate continuous packet-mode traffic using packet engine with wl utility.

Below are the driver and firmware version details:

[root@AT91SAM9 ~]# wl ver

1.141 RC77.0

wl0: Mar 11 2014 12:07:36 version 6.10.190.49 (r461234) FWID 01-da477153

[root@AT91SAM9 ~]#

Running below command to generate continuous traffic:

wl pkteng_start <mac> tx 300 1500 0

But the utility returns error as unsupported.

Below is the generated log:

[root@AT91SAM9 ~]# wl pkteng_start 00:11:22:33:44:55 tx 300 1500 0

wl: Unsupported

[root@AT91SAM9 ~]# dmesg -c

[ 4309.410000] dhd_wl_ioctl: WLC_IOCTL: cmd: 235, ret = -8

[ 4309.420000] dhd_wl_ioctl: WLC_GET_VAR: fbt_cap, ret = -23

[ 4309.430000] dhd_wl_ioctl: WLC_GET_VAR: fbt_cap, ret = -23

[ 4313.680000] dhd_wl_ioctl: WLC_SET_VAR: pkteng, ret = -23

[root@AT91SAM9 ~]#

It looks like the firmware returns the feature as unsupported.

Please provide the steps to support this feature. Do i need to use different Firmware for running "pkteng" utility ?

Yes the mfgtest firmware needs to be used for pkteng commands.

==

The mfgtest firmware is part of the tar file attached to this doc.

Quick Start with iMX6 Ultralite EVK and Mass Market Modules

The insmod_dhd.sh script has an option to load the firmware using the mfg test firmware.

more ./scripts/insmod_dhd.sh

ap_mode=false

mfg_mode=false

while [ "$1" != "" ]; do

        case $1 in

                -ap   ) ap_mode=true;;

                -mfg  ) mfg_mode=true;;

        esac

        shift

done

...

...

...

The mfgtest firmware is located in 43340 directory.

Venkats-MBP-9: ~/work/bcm/from_community/bcm_imx_08_12_2016/43340 : ls

43340.hcd bcmdhd.cal bcmdhd.oob.cal fw_bcmdhd.bin fw_bcmdhd_apsta.bin fw_bcmdhd_mfgtest.bin

hi manojkumar

Yes.  You need the "mfgtest" firmware.  There should be a "WLTEST" string output when you invoke "wl ver" when checking on driver and firmware versions.

Best Regards,

Scott

Where can I get the mfg test firmware?

I know on WICED, instructions to run manufacturing test on a WICED hardware platform are provided in the WICED Manufacturing Test User Guide located in the SDK's <WICED SDK>/Doc directory.

This references an app that is available within the SDK and compiled/downloaded to the board being tested.

We have a Linux based API guide for the firmware here: https://community.cypress.com/docs/DOC-2378

But I cannot seem to find the actual firmware. I will need to check with others.

Thank you vsb for sharing mfg firmware.

I tried the firmware but facing different issue now.

Below are the version details:

[root@AT91SAM9 ~]# wl ver

1.141 RC77.0

wl0: Apr 13 2016 02:45:38 version 6.10.190.61 (r631123 WLTEST) FWID 01-3ff1

when i run below command for tx traffic i am getting an Undifined error.

[root@AT91SAM9 ~]# wl pkteng_start 00:23:a7:7a:b8:98 tx 300 1500 0

[  455.600000] dhd_wl_ioctl: WLC_SET_VAR: pkteng, ret = -1

wl: Undefined error

I have folowed blelow steps:

  • Loaded mfg fw
  • ifconfig wlan0 up
  • wl up
  • wl mpc 0
  • wl pkteng_stop <tx>
  • wl pkteng_start <mac> <tx> <ifs> <frmlen> <nframes>

Please find bleow for more information for further debugging.

pkteng status is as follows:

[root@AT91SAM9 ~]# wl pkteng_stats

Am I following proper steps? Are there any configuration steps need to done before running pkteng ?

Manoj,

Please post this question in a separate thread. Include details of the

1) Version of driver your are using.(where you obtained it from). Is it DHD or FMAC?

2) Please send logs from the time of loading the driver,including commands which show how you load the driver. Better yet, include the logs from bootup.

Thanks,

Venkat
