LPC546xx SDIO Wifi porting from USDHC

[PIHL]

Hi,

I would like to set up Wifi connection by Cypress CYW43012 using LPC54607 MCU. I have it connected through voltage level shifter and I checked that the communication on command line is going both ways without issues.

I was searching for example code for device setup and found out that there is an example for the Cypress Wifi driver for iMX RT1170 (evkmimxrt1170_wifi_iperf_cm7). It uses USDHC1 paripheral instead of SDIO, but used pins are exactly the same. Additionally the example uses sdio library, but have some higher level code added to it.

Do you think that there is a possibility to port this library to LPC54607? 

Thanks,

Piotr

Hello Piotr,

You mentioned the Cypress CYW43012. Murata supports a module with this chipset (link below). If you are using their module perhaps, they may be able to provide more help.

The i.MXRT USDHC module supports the SDIO standard so that shouldn’t be a problem. There are some examples with Cypress chips on the i.MXRT1170 SDK. For the Murata uSD-M.2 there is the  wiced_iperf_4343W_cm7 example. However, please read the included readme carefully as there are Hardware considerations.

There is a guide for an Embedded Artist board i.MX1060 that is helpful to see more details on the SDK examples, albeit this board is manufactured and supported by Embedded Artist and based on the i.MXRT1160, but it may be useful as a general reference.

I hope that this information helps.
