IW61x / IW41x support for LPC5528

[MarcinB]

We are looking for WiFi/BLE module from IW61x / IW41x family to connect with LPC55S28 microcontroller (by SDIo / or SPI .. UART is too slow). 

Is there any chance for support such option in NXP MCUXpresso SDK ?

Hi,

We don't have support for wireless SoC's with the LPC series. The main reason is due to flash limitation. The FW must be stored in the host so it can be streamed into the SoC (the SoC doesn't have flash which means every time the application boots the fw has to be downloaded). Theoretically, you could store the FW on an external flash, but we don't have any reference code for this.

If you would like to use an embedded flash MCU, MCXN947 could be an option.

By the way, there is an example on the RT1060-EVKB which can use the RW612 as NCP via SDIO, SPI, USB, or UART. 

I hope this helps.

Regards,

Daniel.

How about RW610 / RW612 ? We also consider to use this SoC, but we need to connect some large storage as eMMC/SD Card. SDIO interface is slave only ? Am I'm right ?
Is there any other option possible to use it ? (standarx FLEXCOM SPI is 30MHz limited, so it is unfortunately too slow for us )

Unfortunately, seems these are the only options we have. If you would like to know more about the NCP app, there is UM12133 available in the RW61x documentation.

I'm sorry for the inconvenience this might cause you.

Daniel.
