CYW43012 WiFi firmware upgrade

[PIHL]

Hi,

I am using a CYW43012 (Murata LBEE59B1LV) with LPC56407 on a dedicated PCB. I try to set up the WiFi by creating Access Point or scanning local networks to verify the hardware.

At the moment I can reliably communicate with the module using SDIO and enable functions 1 and 2. I can read the state of those functions - function 1 is enabled and ready, function 2 is enabled but not ready.

I have found an example code for RT1170 and CYW4343W using the same initialization protocol. In this example during initialization there is a part of writing firmware for WiFi.

My question are: 

- do I need Function 2 ready to scan WiFi or create Access Point?

- do I need to write WiFi firmware to the CYW43012 before scanning WiFi or creating Access Point?

Thanks,

Piotr

1. Yes. You need to have the sdio completely working before you can start wifi related transactions.

2. Yes, the wifi radio won't boot up without the WiFI firmware.

I am not sure what the LPC56407 is but you can use this https://community.cypress.com/t5/Resource-Library/STM32F469-porting-in-WICED/ta-p/246317 as  a reference for your porting effort.

Thanks
