i use wl tool which is provided from @raks_99  to do 802.11b mode Tx RF testing , but return error -11 when run command "wl phy_txpwrctrl 1".

wl version check:

 # ./wl ver
1.28 RC0.0
wl0: May 2 2019 02:37:41 version 7.45.98.83 (r714225 CY WLTEST) FWID 01-7e9977e3

802.11b mode Tx RF testing  command sequence from Azurewave:

wl pkteng_stop tx

wl phy_watchdog 0

wl country ALL

wl band b

wl 2g_rate -r 11 -b 20

Any help is appreciated.

Any one send me a wl tool static complied for arm926t cpu?

or can we download the wl source code from some where and complie it by ourself? and where is the source  code?

Hi all,

I have sucessfully booted rk3399 5.10.60 linux kernel and loaded the brcmfmac module with and old firmware delivered from firefly team to their sdk: Firmware: /2 wl0: Apr 18 2017 13:54:43 version 7.35.184.1.r5 (A2 Station/P2P) FWID 01-efd4ca0d

This firmware is not supporting SAE. From what i have read, i need a newer one and the question is, is there any, which supports SAE? And if there is where could i find it? If not the my question is, if you plan to add support for this new feature?

Hello, expert

Our product use AW-NM372SM as wireless connect, the chipset of AW-NM372SM is cyfmac43430.Wifi driver is cypress-wifi-v5.4.18-2021_0527, it work well with cyfmac43430-sdio.bin & cyfmac43430-sdio.txt(both are from AZUREWAVE).

Now we need to some RF test and need to replace cyfmac43430-sdio.bin with the cyw43438-7.46.58.26_mfg.bin(also from AZUREWAVE), But at this time the wifi driver fail and exit.

Hi,

The latest FMAC driver doc mentioned WPA3 is supported in STA and AT mode.

Cypress Linux WiFi Driver Release (FMAC) [2021-05-27] 

I just want to double confirm does WPA3 feature support in ALL chip FW(or module, see attached file. whatever SDIO/PCIe/USB) listed on doc??

Thanks.

Austin

Hello,

First the problem: We constantly have an unexpected peak on 3.618 GHz (for channel 1) during the official RF testing of -37dBm while the limit is -47 dBm.

We are using a Raspberry PI Compute Module 3+ with a CYW43438 Wi-Fi module in our product, and this product has to be FCC complaint. 

Now we already have obtained the MFG test firmware for the CYW43438 as well as the WL utility. We also created FCC scripts which will put the chip in all the necessary FCC test modes (802.11b/g/n) in transmit and receive. Here a two examples of those scripts (maybe we do something wrong in these scripts)

# ------------------------------------------------------------
# Transmit 802.11b 5.5 Mbs on channel 1 with a power of 20 dBm
# ------------------------------------------------------------

wl down
wl country ALL
wl band b
wl chanspec -c 1 -b 2 -w 20 -s 0
wl mpc 0
wl ampdu 0
wl bi 65000
wl frameburst 1
wl rateset 54b
wl txant 0
wl antdiv 0
wl 2g_rate -r 5.5 -b 20
wl phy_watchdog 0
wl disassoc

wl phy_forcecal 1
wl phy_txpwrctrl 1
wl txpwr1 20
wl scansuppress 1
wl pkteng_start 00:11:22:33:44:55 tx 100 1024 0

# ------------------------------------------------------------
# Receive 802.11b on channel 1 with a power of 20 dBm
# ------------------------------------------------------------

wl down
wl country ALL
wl band b
wl chanspec -c 1 -b 2 -w 20 -s 0

wl phy_forcecal 1
wl phy_txpwrctrl 1
wl txpwr1 20
wl scansuppress 1
wl pkteng_start 00:11:22:33:44:55 rx

We already tried turning off all major (and even minor) other components on our product to check if they might be the issue, but so far no luck.

As soon as we execute wl down the peak is gone, and executing the wl up command will bring back the peak. This is why we ask on this forum, in the hope someone knows what is going on.

I included a screenshot of the peak in the attachments.

Note: the screenshot was made with our own equipment hence the difference in the dBm strength.

Dear Sir,

I am working Raspberry Pi 4/3, 64bits linux enabled project. I would need to perform wl command for FCC test. I found several topic about similar request, and I tried to submit a case for technical support to get mfg firmware. however, due to COVID-19, I could not submit the new case.

 May I have your support to have proper wl and mfg firmware for FCC test? Thanks.

Although i have success to make my cypress wifi work.,but i notice that there is a error when wifi bringup:

[ 135.200000] cfg80211: failed to load regulatory.db

And i have read though  a Regulatory wiki(https://wireless.wiki.kernel.org/en/developers/Regulatory), but I don’t have enough expertise to really understand it.

Should any one tell me how to do deal with wifi regulatory？  if  our wifi device will deploy around the world.

Hi

Is there any documentation on NVRam available parameters? I understand NVram is to configure WiFi for best performance. And every module supplier has different NVRam parameters value.

I would like to know what is available to configure, not the value for each parameter.

Thanks,
