Show LessHi there,
We are trying to fcc wifi certify our project which uses a custom buildroot toolchain and arm processor.
We need help to compile the wl_tool so we can proceed with certification, but we need it to be cross compiled for our architecture (arm 32bit).
Can I ask a representative to help us to compile it with our custom toolchain?
CPU Info:
- armv7l
- little-endian
- hard-float ABI
- neon/vfpv4
Custom Toolchain Instructions:
- download toolchain
- extract toolchain:
tar jxf arm-co6-linux-uclibcgnueabihf_sdk-buildroot_2021.02.1.tar.xz - cd to arm-co6-linux-uclibcgnueabihf_sdk-buildroot
- ./relocate_sdk.sh
- add toolchain into path e.g.
export PATH="$PATH:$PWD/usr/bin" - Set cross compile variables:
export ARCH=arm
export CROSS_COMPILE=arm-co6-linux-uclibcgnueabihf-
Tagging @VinayakS_26 / @raks_99 / @DoubleLo as I found they have helped another customer to do this.

Hi
Our product is working on imx6u platform and wifi module is 1mw, the wifi is working fine when I specify a channel no. like 1 or 11 in hostapd.conf, but I encounted a problem when configuring acs in hostapd.conf.
The embedded linux version is 4.19, and hostapd version is 2.6.
Hostapd is built with CONFIG_ACS.
and I tried both channel=0 or channel=acs_survey.
But I always get the same error message in the log file, "No survey data received. ACS: unable to collect survey data", and then wlan0: AP-DISABLED.
Do you have any suggestions for thie issue?
Thanks a lot.
Show LessHi All,
We are using brcm4356 chip on Xilinx and we are seeing the below errors. We use wifi AP mode, and use iperf to test Throughput.
Could you give me some help from Cypress?

Hello,
We are moving from the cymdhd driver to the brcfmac backport with an CYM43455. We needed to set the following dhd build flags in order to achieve good 5Ghz WiFi throughput. What are the equivalent settings in brcmfmac?
DHDCFLAGS += -DCUSTOM_AMPDU_MPDU=16
DHDCFLAGS += -DCUSTOM_AMPDU_BA_WSIZE=64
DHDCFLAGS += -DCUSTOM_GLOM_SETTING=8
DHDCFLAGS += -DBCMSDIOH_TXGLOM -DCUSTOM_TXGLOM=1
DHDCFLAGS += -DDHDTCPACK_SUPPRESS
DHDCFLAGS += -DRXFRAME_THREAD

Thanks!
Show LessHello,
I am trying to test the bluetooth functionality of the CYW54591 chipset on the NVIDIA Jetson Nano (running Linux 4.9). The PCIE (WiFi) interface is working as expected but I am not able to 'attach' to the UART interface of the m.2 module that I am testing. I've tried different hciattach commands, such as:
hciattach /dev/ttyTHS2 any 921600 noflow
but I am not able to find one that successfully finishes initialization. Is there an 'hciattach' command that should work for the CYW54591?
I don't see any drivers specifically for the bluetooth in the driver package that I downloaded for WiFi:
is there another package that contains the bluetooth drivers for the chip?
Thanks for your help
Show LessHello,
As channels 12 & 13 seem to be disabled, I assume wifi chipset is configured for US.
How can I change the country under Linux?
I add country=FR in wpa-supplicant conf file without success
I try to use iw without success too
# iw reg get

What is Cypress recommend way to set the Country in Linux?

Hi,
I have been trying to connect phone on the i.MX8QM development board with Bluetooth module Cypress CYW4356. My phone is connected to the board and i am able access the caller app on the board. Using that i made a call to another device and calling is done. But no audio is getting in both devices, which i guess some issues in routing call from the board. The board is connected with a speaker system and we can able able play a music from phone via Bluetooth using an app (media player). I think Bluetooth audio routing has any issue. Could you suggest a method so that i can able to use Bluetooth for telephonic purpose. Thank you.
Regards,
Aravind
Hello,
We're using a CYM43455 with Android 8.1, Kernel 4.9, with the brcmfmac driver from the backports package in Cypress Linux WiFi Driver Release (FMAC) [2020-09-25].
We are not able to achieve the same 5GHz throughput using iperf in lab conditions using the brcmfmac driver compared to our vendor's (AzureWave) preferred cymdhd driver. The cywdhd driver achieves 103 Mbits/sec in client mode, while the brcmfmac driver only achieves 86 Mbits/sec.
For the cymdhd driver to achieve its highest throughput, its driver required optimizations such as "tcp delayed ack", "rx frame thread" concurrency, and others that do not look to be available options in the brcmfmac driver.
What is the highest 5Ghz throughput we can expect with the bcrmfmac driver and CYM43455, considering the cymdhd driver can achieve 100+MBits/sec on the same hardware under the same conditions? Is it possible to match the performance of the cymdhd driver when the offloading and concurrency it depends on does not seem to be available in the brcfmac driver?
Thanks!
Show LessHello,
We're currently using the BCMDHD driver with an Allwinner A50 BSP with Android 8.1 oreo and Kernel 4.9. We are moving to the CYW43455 with Azurewave as our module provider and we're not clear what would be the best driver to use:
1. BCMDHD is provided in the A50 BSP, and we have been using it successfully with our previous module supplier
2. CYWDHD is provided by Azurewave as their preferred driver, but seems like it is an older fork of BCMDHD and has seen very little development compared to the BSP's BCMDHD.
3. BRCMFMAC is Cypress's preferred path forward for security updates and feature support (WPA3/DPP etc), but we're not sure how risky / labor intensive it is to port it to our BSP's 4.9 kernel?
Any insights would be much appreciated - which driver should we use? Thanks!
