Hi Team,

We have integrated CYW43444 module with android and everything working properly.

We have to do RF testing for WIFI.

We have WL binary.. 

But We are getting error for somw commands. Can you please help here.

evk_8mm:/ # wl pkteng_start 00:11:22:33:44:55 tx sync 40 1000 0
wl: error -23

evk_8mm:/ # wl country ALL
wl: error -2

evk_8mm:/ # wl phy_watchdog 0
wl: error -23

Requirement :

1. Transmit in continuous wave mode.
2. Transmit in Packet mode (No of Packets configurable).
3. Transmit in continuous stream (duty cycle more than 90%).
4. Receive in packet and continuous mode (Time configurable).

What needs to be done for above requirement? 

Also following commands are not working:

10 wl country ALL
11 wl dump
12 wl pkteng_start 00:11:22:33:44:55 tx 20 1500 0
13 wl pkteng_stats
14 wl nvram_dump

Hi All,

My company use BCM43455 wifi- Bluetooth modules in our product. For Radio testing of both wifi and BT, I have to put them in test mode for transmitting continuously on different frequencies. How can I achieve that through Linux?

Can somebody please share how that can be done?

Any reply is really appreciated.

Thanks,

Hi Team,

We have integrated cyw43455 with IMX8MM processor in android 11 code base and it is working fine.

but as per the requirement we need to disable wifi for sometimes using reset pin. 

When I make

1. regon pin (reset pin) low - WIFI disable 

2. After that making regonreset pin high - WIFI should turn on (but it is not working) . - looks like power on sequence issue.

Could you please help here to disable wifi using reset pin? What changes need to be done here ?

thanks

Hi,

I want to port driver for CYW43455. I used this  Cypress Linux WiFi Driver Release (FMAC) [2020-06-25]  ,

Target platfrom is ST sta1275 DV12.5,

During the cross compilation of modules, I have seen the following warning.

root@sta1275-evb-mmc:~/aher_ko# insmod compat.ko
insmod: ERROR: could not insert module compat.ko: Unknown symbol in module

dmesg shows :
[ 59.569745] compat: Unknown symbol kmem_cache_alloc_trace (err 0)
[ 59.569905] compat: Unknown symbol __gnu_mcount_nc (err 0)

Could you help to fix this issue? Thanks a lot.

I am interested in using wifi easy connect/Device Provisioning Protocol, but the brcmfmac driver that is in upstream Linux kernel does not seem to have support for it.

I see in the linux-wireless mailing list archive that you did do one attempt to send in a patch for it back in December 2020.

But that one was rejected because your patch did not apply cleanly to latest Linux tree: https://lore.kernel.org/linux-wireless/20201209072159.354AAC433ED@smtp.codeaurora.org/

I do not see a second attempt.

What is the reason for this?

And is it only the kernel were the support is still missing, or is there also still work on the firmware side to be done before easy connect is in an usable state?
