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.

We have use brcmfmac on TI and NXP platform with CY wifi chip.
It seems that the SDIO hardware is different between NXP and TI because it is needed to set "sd_sgentry_align = <512>" in dts node to let brcmfmac runs on IT's SOC.
My understand is TI's SDIO hardware can not handle variable length data block but NXP can.
The question is that I can not find the same parameter sd_sgentry_align in bcmdhd driver source code.
Is there a same parameter in bcmdhd code?
And If some one has the experience on porting bcmdhd to TI's SOC?

#### Build the kernel image
```bash
#1. Have the BSP kernel source available
git clone https://source.codeaurora.org/external/imx/linux-imx
cd linux-imx
git checkout imx_4.9.88_2.0.0_ga
#2. Set up build environment and kernel configuration
source /opt/poky/1.8/environment-setup-cortexa7hf-vfp-neon-poky-linux-gnueabi

How can I do the following in step 2?
source /opt/poky/1.8/environment-setup-cortexa7hf-vfp-neon-poky-linux-gnueabi
I think you need to download from Yocto, please tell me about the download procedure and installation method.

Show LessHi experts,
We are using Linux BSA_Server to implement BT Sink function. Application layer uses UIPC_Open(tUIPC_RVC_CBACK) to receive AVK PCM/AAC data from BSA_Server.
The question is: what AVK audio receiving timeout should we set? It also means how big of intermediate buffer should we use before sending the audio data to audio ALSA interface. We notice the receiving of most of the audio package is timely and stable. But some packages may arrive application layer with a significant delay, some one may be lost. We guess it may be due to interference and audio package re-transmission.
We want to make sure that all the audio packages arriving device end before Bluetooth A2DP timeout can be played out normally.
What's the application layer audio receiving timeout should we set?
Thanks very much for your time!

Show LessHello,
Firstly, this is my setup

# DUT1 #===================================# DUT2 #

###################
# #
# Spectrum analyser #

###################
I putted DUT1 in tx mode in channel 7 and txchain 3 ( tx in 2 antennas), and i putted DUT2 in rx mode in channel 7.
when i put the DUT2 in rxchain 1 ( Antenna 1) and check the value of wl pkteng_stats to get the rssi : i get the value of -14 dbm
and when put the DUT2 in rxchain 2 (Antenna 2), i have a fixed value of rssi : -128dbm
when i put the DUT2 in rxchain 3 (Antenna 1 and 2) i have -14 in rssi value.
I want to know why the antenna 2 is blocked at -128dbm ?
is there any other commands to get the rssi value by antenna ?
i already tested the command : wl phy_rssi_ant and the retuen was :
rssi[0] 0 rssi[1] 0 rssi[2] 0 rssi[3] 0
the command : wl rssi return 0 also.
Best regards.
Show LessI'm using a AP6476 WiFi+BT combo module with BCM43362.
Until recently I have been using an old firmware from linux-firmware (43362a2-roml/sdio-g-pno-pktfilter-keepalive-wapi-wme-p2p Version: 5.90.195.89 CRC: bd1e3e5a Date: Mon 2013-04-22 17:24:44 CST). With the old firmware, WiFi and BT work together without any problems. Only P2P is broken.
Now I'm trying to use the updated Cypress firmware for BCM43362/CYW43362 from Cypress Linux WiFi Driver Release (FMAC) [2019-05-08] (version: 5.90.251). It works mostly, including P2P, but WiFi/BT coexistence appears to be no longer working. WiFi stops working as soon as BT is active. This looks like a firmware regression since it works fine with the older firmware.
The WiFi problem can be seen by running continuous ping and then enabling BT. The ping response times go up to 20 seconds. (see ping.txt). As soon as BT is disabled, ping is back to normal.
Was there any change in the firmware that broke WiFi/BT coexistence? Is there any way to avoid this problem? Maybe with a change in the NVRAM file (attached)? In general, can the Cypress firmware be used for all BCM43362 chips, including AMPAK?
Thanks in advance,
Tom
Show LessHi expert,
We are using Linux BSA_Server to implement BT Sink function. Application layer uses UIPC_Open to receive PCM/AAC data from BSA_Server.
The data buffer pointer is: pBuffer = ((uint8_t*)(p_msg + 1)) + p_msg->offset;
The data buffer lenght is: p_msg->len
Q1. Is the maximum value of p_msg->len always 1024?
Q2. Where to configure this value or if it's a fixed value and can't be change?
Thanks very much and look forward to your feedback!

Show LessHi Cypress:
My product is using cyw43455 which is under CE certification process currently,
So my question is similar on following two threads, but they are all locked, so I raised another thread
Manufacturing test firmware for 43455
I am using wl on linux, on the raspberry pi 3 B+ model(cyw43455) with mfg.bin.
I'd like to ask What are the wl commands to set cyw43455 to transmit at a specified channel, a specified bitrate?
And how to set cyw43455 in receiver mode? Thanks a lot

Show LessHello,
We are trying to integrate a 1DX Murata module (based on BCM43430 chip) on a productbased on an Atmel (now Microchip) ATSAMA5D31 MPU running a 3.10 Linux Kernel. Is there any drivers revision compliant with such setup ?
Regarding Wifi
When compiling the out of tree backport provided on the following cypress webpage (https://community.cypress.com/servlet/JiveServlet/download/15932-1-39799/cypress-fmac-v4.14.52-2018_0928.zip) , we ended up with four kernel modules, including the low level cfg80211 layer.
Is there any (potentially old) version where cfg80211 did not need to be backported ?
Indeed our goal is to have a single kernel on several different products with different WIFI/BT modules, we would appreciate to keep the standard cfg80211 driver and just to add a few more kernel modules to support a BCM43430 based radio module.
Regarding Bluetooth
Bluez5 seems to be manadatory to support bcm43xx device when using hciattach. Could you confirm?
Is there any documentation regarding kernel configuration to support the bluetooth feature of BCM43430 chip? We did not find any related information on cypress website
