Hi All,

We are using brcm4356 chip on Xilinx and we are seeing the below errors.  We use wifi AP mode, and use iperf to test Throughput.

Could you give me some help from Cypress?

We do not support BCM4356 from Broadcom. We support CYW4356. Please clarify whether this is a Cypress CYW4356 chip.

Hi DS_Lin,

  My linux version is 4.14.0, so I use cypress-fmac-v4.14.52-2018_0928  driver. And our chip is brcm4356s(sdio interface).
