Connecting M.2 modules

I am planning to use a Murata M.2 Wi-Fi/BT module with my i.MX 6UL EVK. However, this EVK does not have the M.2 interface? How do I connect the Murata module to the EVK?

Murata has a uSD-M.2 adapter for NXP’s i.MX6 platforms. With this adapter, you can evaluate Embedded Artists’ M.2 1DX, 1MW and 1LV EVB as Fig 1 shows. Fig 2 shows how it works together with i.MX6 UL EVK. For more information, please visit the landing page of Murata wireless solutions.

Hi,

>>I am planning to use a Murata M.2 Wi-Fi/BT module with my i.MX 6UL EVK. However, this EVK does not have the M.2 interface?

i.MX6UL has no PCIe or SATA interface, so M.2 connector is not supported on i.MX6UL EVK board.

>>How do I connect the Murata module to the EVK?M.2 connector is designed for SATA signals or PCIe signals, i.MX6UL has no these 2 kinds of signals. So if you want to use M.2, you will have to define signals on the connector by yourself, and design a WIFI card with M.2 interface.

Have a nice day!

Hi Wigros

Yes, i.MX6UL EVK doesn't have PCIe or SATA. But it has SDIO interface.

Embedded Artists' Wi-Fi/BT M.2 modules use key id; E, which defines pinning for PCIe(2x), SDIO, UART, PCM, USB2.0, and I2C interfaces. For more information, please refer to Embedded Artists' documentation for M.2 here.

The chipset of the EVBs mentioned in Fig1, 1DX/1MW/1LV are all SDIO interfaced, so they can talk to i.MX 6UL via the M.2 adapter. Murata has provided software support for this adapter and validated it on NXP's i.MX6 UL/ULL EVK, i.MX6SL EVK, i.MX 6SX SDB, and i.MX 6Quad SDB. For more detail, please refer to Murata's quick start guide. https://wireless.murata.com/datasheet?/RFM/data/murata_quick_start_guide_linux.pdf

Best regards,

Bill

Hello Bill,

Yes, right. SDIO signals can be defined on M.2 connector. So WIFI module with M.2 can also be connected to the connector.

Next, you need to confirm with Murata whether there is a SDIO-based M.2 module, if there is such a module, there will be no problem.

Have a nice day!

Hi I am using an iMX8MM Mini lpddr4 cpu2 EVK board. I intend to connect the Murata uSD to M.2 connector Rev A board to microSD card slot of the iMX8MM mini EVK board and connect CYW54591 on M.2 connector of murata.

I have made the connections for this board based on Section 6.3 of this link.

https://www.murata.com/-/media/webrenewal/products/connectivitymodule/asset/pub/rfm/data/murata_user_guide_linux_cyw.ashx?la=en-sg&cvid=20210615064931000000

Does MicroSD card slot of iMX8MM support reconfiguration of SDIO or SDMMC on microSD card slot?

I am getting the following issues from when make the setup as described above.

IF573 with IMX8m mini

Sadatan123 — Wed, 28 May 2025 09:55:22 GMT

I am trying to plug a IF573 module connected on IF513 DVK to uSD card slot of IMX8M mini EVK using a high speed cable and conveter like as given below:

It's not working .
Also attched here is chages we made in default IMX8m mini image and also the logs of teraterm.

Please let me know what could be the reason for Wifi module not getting detected.
