Hardware details,
Cypress Chipset Default Options WLAN Interface Devices Supported
============= ======= ======= ============== ===============
CYW43455 1MW 1LC, 1HK SDIO 802.11a/b/g/n/ac
we have integrated the cypress chipset in our PCBA with our Host processor (Device: Cortex-A7) and we booted the device. I got the attached Manufacturing test firmware files(cypress-mfgtest-v5.4.18-2020_0402.tar.gz) from murata support team. Placed the firmware files in /lib/firmware/brcm of our linux file system and we could see during the boot up of the device we observed below logs
brcmutil: loading out-of-tree module taints kernel.

In a high level i could see the manufacturing test firmware which shared doesnot contain "brcmfmac43455-sdio.txt" could you please share it.
we are planning to use the below commands for continous TX testing:
wl pkteng_stop tx
wl out
wl down
wl frameburst 1
wl ampdu 1
wl country ALL
wl rateset 54b
wl bi 65000
wl phy_watchdog 0
wl mpc 0
wl txchain 3
wl mimo_bw_cap 1
wl band b
wl txbf 0
wl chanspec -c 1 -b 2 -w 20 -s 0
wl 2g_rate -r 6
wl up
wl disassoc
wl phy_forcecal 1
wl txpwr1 -o 19
wl pkteng_start 00:11:22:33:44:55 tx 20 1500 0
Please confirm
Thank you.

You can contact Murata to obtain the nvram file brcmfmac43455-sdio.txt. Regarding the above wl commands, it can be used for testing 802.11g mode. Also wl txchain should not be 3 because 43455 is not a MIMO chip. You can use 1 or 2.

Please share the manufacturing test firmware for the cypress chipset 43455 for the version 7.45.173 for performing “RF testing”
We require below three files,
brcmfmac43455-sdio.bin
brcmfmac43455-sdio.clm_blob
brcmfmac43455-sdio.txt
whom to contact?

Thank you for your response.
Am using the below commands for Tx transmission test:
wl pkteng_stop tx
wl out
wl down
wl frameburst 1
wl ampdu 1
wl country ALL
wl rateset 54b
wl bi 65000
wl phy_watchdog 0
wl mpc 0
wl txchain 1
wl mimo_bw_cap 1
wl band b
wl chanspec -c 1 -b 2 -w 20 -s 0
wl 2g_rate -r 6
wl up
wl disassoc
wl phy_forcecal 1
wl txpwr1 -o 19
wl pkteng_start 00:11:22:33:44:55 tx 20 1500 0
All commands are working as expected without any issues , i could able to capture the power and frequency in the spectrum analyzer without any issues.
Query1:
if i give power value as 0 dbm i get below error
wl txpwr1 -o 0
One or more parameters have invalid values
why is it so?
as per the command description says
"Use this command to change the power in real time. Can also use the quarter step command wl txpwr1 -o -q XX, where XX is any value between 0 to 100."
Query2:
I need wl commands for doing wifi (rx) reception testing . Could you please share the same over here ?

Hello Mara,
I see that you shared the manufacturing test firmware, but can you share the standard firmware of this version please ?
Thank you for your time,
Best regards,
