Hello All,

I would like to get the latest Cypress's Linux brcmfmac driver and firmware support package for cym43455.

Also checked the latest release version v5.15.58-2023_0523 but no support for cym43455 firmware is found.

 

Thanks in advance

Hello to everybody!
I'm working with the CYW954907AEVAL1F Evaluation kit, that mounts the CYW54907.

I would like just to ask if this chip support SAE-PK (the WPA3 feature) and/or if it allows to activate the Transition Disable mode (and if so, which mode is supported... like WPA2 -> WPA3, SAE-> SAE-PK, etc.).

Thank you in advance 🙂

Hi,

Can you please advise if the CYW43012 device and its evolution CYW43022 have integration with Apple Homekit (direct IP integration not dependent on Matter). This requires the PSoC to have a library that implements mDNS along with other homekit requirements.

Thank you,

Marcelo - FAE at Neutronics

Since the IIC of CYW43907 does not support clock stretching, I have to use bit banging I2C driver. On this driver, it takes up to 100us to switch IO port input and output, resulting in extremely low IIC clock. Could you please provide me a register manual? I would like to operate the register directly Show Less

Using Fedora38 on two systems with BCM4356 802.11ac Wireless Network Adapter I get these messages and WiFi results:

Dell Inspiron 660

2.4GHz and 5GHz are not working

For both cases I have tried with several available firmware files that we can get from linux-firmware and although I get rid of the log error, nothing changes.

For the imx board, we need a configuration file to get the 2.4GHz band working and get a correct association although 5GHz band is still not working. The configuration file that I have tested is a generic one (https://chromium.googlesource.com/chromiumos/third_party/linux-firmware/+/f151f016b4fe656399f199e28cabf8d658bcb52b/brcm/brcmfmac4356-pcie.txt).
While, for the commented intel platform, the configuration file is not necessary to get the 2.4GHz band working and get a correct association but 5GHz band is not working with everyone I have tried.
I have read that this configuration file is related to some nvram configuration values but nothing else.

We would need to be able to use the 5GHz band for both cases.

I have asked to NXP, Intel and Broadcom and everyone redirects me to Infineon in order to solve these issues with this card.
Could yu help me? Could you clarify which firmware and configuration files are necessary?

Thanks

Hello team,
We have a custom hardware board based on STM32MP1 mpu along with some other peripherals too.
For our use case, we are using yocto linux and uses openstlinux (arm-openstlinux_weston-linux-gnueabi-gcc), Kernel version 4.19.9 .

For the WiFi, we are loading the following Cypress WiFi drivers to the kernel.
-brcmfmac.ko
-brcmutil.ko
-cfg80211.ko
-compat.ko

The network works fine, but, when I try to transfer some files from my target board to my host machine, for ex. using scp,
the network crashes, and I am forced to do a Power On Reset to restore the network.
I am pasting the log below.

What we were told is that we need to use a backport of the drivers to solve this problem. I tried v5.10.9-backports &
v5.15.58-backports but I am still getting the same problem.
Please help me out. I request to provide the exact backports to solve this issue.
