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,
I want to make a wireless-repeater with a RPI3B+.
i could configure the RPI in client mode ( so the RPI connects to an AP), and also i succeeded to configure it as an AP bridged to the eth0.
But when i tried to set-up the repeater configuration with 'relayd' , it didn't work at all.

Show LessHello . I wonder if Cypress provide support for a2dp offload feature in Android . The BT chip is 43455 . For now we use default configuration and sound transmitted to BT chip by UART . However audio is slightly choppy .
Thank you .
Show Lesshi,we are use 43362 as softap,Test transmitting signal,This is shown below:
In nvram, maxp2ga0=74,softap channel is 1(2412MHz)
2.After observation for a period of time, abnormal waveform was found to be generated, and the abnormal wave power was very large,The figure above shows the maximum holding waveform over a period of time
In dynamic observation, abnormal waveforms appear and disappear immediately
3.The anomalous wave (overpowered) frequency point is also regular, always shifting about 5MHz to the right of the current channel frequency point
4.Please help to check the cause of this problem. I think the 2.4g waveform is not caused by us, but by the chip itself
Looking forward to your reply!
Show LessIs the calibration current documented anywhere ?? We see periodic ~20ms 600mA calibration current for BCM43353 and BCM4343W. Does not
seem to be documented in the chipset datasheet ...
600mA for 20ms is a problem for USB powered devices (500mA power limit).
Do all Cypress chipsets require this type of calibration current ??
Show LessI have a client using the warp7 board with murata 1DX module with Cypress/CYW4343W.
https://www.element14.com/community/community/designcenter/single-board-computers/warp7
Is this supported with the latest FMAC driver? I built a kernel with the latest FMAC [2019-10-31] following the README for Linux Stable v4.14.77 but when I run it I get an error in the log that it failed to load the firmware .bin file and I don't see the wireless come up.
If I build with the freescale community bsp (Yocto thud) which supports the board (imx7s-warp), I get a linux 4.20.0-rc6 kernel with a brcmfmac driver, is that just an older FMAC driver?
This is similar to this discussion post by GrahamS_21 which is locked but was not answered publicly.
"I have a customer trying to use the iMX7s-warp board, which has a type-1dx module (CYW4343W)
Our latest FMAC driver and firmware supports kernel 4.1.15 which has no MACHINE imx7s-warp
They imported the Yocto meta-layer for the imx7s-warp from another BSP but this overrides the preferred kernel and pulls in 4.1.32 in which then it becomes a kernel source/header file headache for FMAC.
The current Yocto BSPs all support the imx7s-warp ( 4.1.32 up ) and have the bcmdhd and brcmfmac drivers within, the brcmfmac doesn't actually work but as it's close to FMAC as far as I know - it may be a good starting point for a possible port?
Can we provide some guidance on how to enable this feature? for reference this works ok on the iMX7d board, just not the WARP one."
We want to use the latest driver to help diagnose or prevent some connection issues that were observed with an older kernel and driver.
Regards,
Aaron
Show LessHello everyone, when I designed the board using the BCM43438, I started the WL_REG_ON this pin and thought that the chip should have worked properly and that the measurement of each voltage was correct. But when I measured the voltage at both ends of the crystal, I found that there was no voltage, what was the reason? I use what seems to be the official recommendation of 37.4MHz crystal and 12pF capacitor.
Show LessHi,
This question is related to the following discussion.
Advance notification on WLAN IC / FMAC driver hangup?
To output debug log, I suppose I have to define DEBUG and enable the definition of real brcmf_debugfs_fws_stats_read() which outputs multiple parameters.
If I managed to re-produce the hangup, which parameters to look for as general indication of hangup?
Best,
Wataru Sugimoto
Show LessHello,
I am in the process of upgrading to the 2019-05-03 release of the FMAC driver and I noticed today that this release is no longer available in the community site and that 2019-10-31 is now available.
Was it removed on purpose because it should not be used? Is 2019-05-03 safe to use or should I skip this release and use 2019-10-31 instead? I am using the Murata 1DX module (CYW4343W chipset).
Thanks,
Jesse
Show LessHi All,
We are working on NXP's imx8mq processor-based custom design. We have interfaced with the Murata's LBEE5HY1MW-230 module through the SDIO interface.
We used the 4.14 Linux distro for our development. This module's Wi-Fi and Bluetooth is working fine.
For the RF CE certification, we need to communicate with channel no 13.
For that, We configuring one router with channel no 13 with AP mode. Now we are trying to scan this SSID on our Murata's LBEE5HY1MW-230 module.
we are not able to connect the 13th channel of 2.4GHz band. It seems the country code issue with our firmware.
Can you please let us know where the changes are required to make connectivity with the 13th channel?
Please note there is no issue with connectivity up to the 11th channel.
Let me know if you need further information.
Thanks,
Parth
