I have asked about CYW43353 bt host wake here:

https://community.infineon.com/t5/Wi-Fi-Bluetooth-for-Linux/CYW43353-BT-host-wake-on-LWB5/td-p/471652

The thread was then locked and the accepted answer points to tutorial for CY20xxx parts.

Forgive me asking,  but will this actually work with CYW43353 series as well ?

Is it true then that the commands for BT host wake are the same across the whole range of your BT ICs ?

Kind regards.

I bought some amount of CYW20719B1 (CYW20719B1KUMLG in specific) for some project I'm working on. I set them on a small board with a UART connection. I got them working with BtAttach and was able to communicate using standard Linux bluez. However, all of them have the same BT-Mac address of AA:AA:AA:AA:AA:AA. My question is what's the simplest way to flush a new address to the chip, as I have many boards to process. I read in this very forum something about .btp files, but either I don't understand something, or I don't have the .btp file for this chip. Where do I get the right .btp file if I really need one?

Thanks ahead,

Assaf

Hello,
We have a custom hardware board based on STM32MP1 mpu along with cypress43455 and 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 . We used to get the kernel oops message and the network crashes when I copy files bigger than 1MB from the target to host (https://community.infineon.com/t5/AIROC-Wi-Fi-MCUs/The-Network-Crashes-while-transferring-files-over-WiFi-Need-Backports-for-kernel/td-p/462819 ).

So we decided to use the latest backport drivers, and downloaded the latest cypress linux WiFi driver release [ cypress-fmac-v5.15.58-2023_0801 ] ( https://community.infineon.com/t5/Wi-Fi-Bluetooth-for-Linux/Cypress-Linux-WiFi-Driver-Release-FMAC-2023-08-01/td-p/459849 ).

We successfully compiled the drivers from the backport  as per the software user guide.

And for the firmware, since those were missing in the recent releases, used the cyfmac43455-sdio.bin and cyfmac43455-sdio.clm_blob files from 2022_0511 Release from https://github.com/Infineon/ifx-linux-firmware/tree/dc38e700612b334080e0b6df69070a88c4c2a12b/firmware . 

For the nvram file cyfmac43455-sdio.txt, we got it from murata ( https://github.com/murata-wireless/cyw-fmac-nvram/blob/master/cyfmac43455-sdio.1MW.txt )

We copied the new driver files and all the above mentioned files and booted the target board, but, the WiFi interface (wlan0) itself is missing.  There is no network.
