Hi Infineon, Can I know if CYW4373E supports AP mode? If CYW4373E supports AP mode, how many device links (max.) when AP mode of the CYW4373E? Can link 10pcs and more devices in AP mode? Thanks! Show Less

Hi Team,

 

I could see the mainline has support for brcmfmac driver in the 6.1 kernel. But I couldn't get the wifi up on my device.

I could see that your GitHub firmware was updated up to 5.15.58, could you guys share the updated firmware for 6.1 kernel?

Thanks,

What guidance does Infineon offer to reduce power spikes with CYW43012 based designs.

There appear to be inrush power spikes at power-on and wake-up.

A CYW43012 based Module appears to need about 600mA-700mA peak current consumption. 

Are there options to skew or sequence functions that require large inrush to limit peak current to 500mA?

Hi,

I was trying to cross compile the cypress-fmac driver for my Ambarella S3L platform.

I prepared the .config with this command:-

make -b KLIB=$MY_KERNEL KLIB_BUILD=$MY_KERNEL CROSS_COMPILE=/usr/local/linaro-armv7ahf-2017.08-gcc7.1/bin/arm-linux-gnueabihf- defconfig-brcmfmac

I executed the build with this command:-

make -b KLIB=$MY_KERNEL KLIB_BUILD=$MY_KERNEL ARCH=arm CROSS_COMPILE=/usr/local/linaro-armv7ahf-2017.08-gcc7.1/bin/arm-linux-gnueabihf- modules

Note that, MY_KERNEL is pointing to the installed SDK linux folder /kernel/linux-3.10_s3l.

However, I encountered this kind of errors:-

<TOPDIR>/v5.15.58-backports/include/linux/list.h:308:2: error: implicit declaration of function ‘smp_store_release’; did you mean ‘__release’? [-Werror=implicit-function-declaration]
smp_store_release(&entry->next, entry);

<TOPDIR>/v5.15.58-backports/include/linux/list.h:326:27: error: implicit declaration of function ‘smp_load_acquire’; did you mean ‘__acquire’? [-Werror=implicit-function-declaration]
struct list_head *next = smp_load_acquire(&head->next);

<TOPDIR>/v5.15.58-backports/backport-include/linux/time.h:5:10: fatal error: linux/time64.h: No such file or directory
#include <linux/time64.h>
cc1: some warnings being treated as errors
compilation terminated.

Is there any patches required to fix this? The kernel in this instance is v3.10

Thank you.

Are there examples of using LInux' Traffic Control "tc" commands to reduce power consumption of WiFi modules?

Does Infineon support Linux' Traffic Control "tc" commands?

Or stated differently, is there anything built into or missing from Infineon's radios that would preclude use of Linux' "tc" commands?

I'm specifically interested in modules based on Infineon's lowest power WiFi silicon, CYW43012 and CYW43022.
