Unfortunately, the BCM4334 is not one of the products supported within the broad market and here on the community website.
Please work with the local/regional Cypress sales rep/distributor that enabled you for this product and ask them to line up factory support.
Unfortunately, WiFi SoC designs are not considered broad market and thus not supported here on the IoT Community (very limited direct support as well). You will want to reach out to the Cypress personnel in your region that enabled you for this device and ask them to setup direct factory support if possible.
Also note that your schematic says proprietary and confidential.
