Is it possible to connect WiFi chip AP6256 to the sdmmc3 and configure sdmmc3 to work with WiFi chip?
It is not guaranteed and depends on your tuning result. For Jetson nano, the SDMMC3 port is a SDIO port for your usage.
Thank you for your answer!

Can you help me with this issue? I can’t realize what is going on. Thank you!
P.S.: Interesting. I have find that in Linux 4 Tegra have “Broadcom FullMAC wireless cards support” in the “nvidia/drivers/net/wireless/bcmdhd”. How can I compile this module?
Yet another thread.
I found that file “bcmdhd.ko” already presents in “/lib/modules/4.9.337-tegra/kernel/drivers/net/wireless/bcmdhd” directory. I tried to load it via sudo modprobe bcmdhd.ko but error was modprobe: FATAL: Module bcmdhd.ko not found in directory /lib/modules/4.9.337-tegra. I copied “bcmdhd.ko” to “/lib/modules/4.9.337-tegra/” and did sudo depmod after that I tried sudo modprobe bcmdhd but error is
modprobe: ERROR: could not insert 'bcmdhd': Invalid argument
modprobe: ERROR: ../libkmod/libkmod-module.c:979 command_do() Error running install command for bcmdhd
modprobe: ERROR: could not insert 'bcmdhd': Operation not permitted
The question is: how can I load “bcmdhd.ko”?
I tried to load module with
jetson@rover:/lib/modules/4.9.337-tegra/kernel/drivers/net/wireless/bcmdhd$ sudo insmod bcmdhd.ko "firmware_path=/lib/firmware/bcmdhd/fw_bcmap6256.bin nvram_path=/lib/firmware/bcmdhd/nvram_ap6256.txt"
command . Result is:

How can I fix this error?
Sorry for the late response.
Is this still an issue to support? Any result can be shared?
I’m still working on it. Unfortunately, it is still issue and I not yet have any solution.

I need to switch mmc1 to SDIO mode not SDHCI. Is it possible to switch mmc1 to SDIO?
I have attached my dmesg.
The main question is how to enable Wi-Fi on the sdhci@700b0400?
The second problem: I can’t see mmc1 in the dmesg. Instead there is

Hi,
Actually the basic question here is not asking someone to guide you at this moment.
The issue here is does the device tree really match to your hardware design? We are not talking about you just keep trying A,B,C,D or any posts from anyone else. You have to tell others about your hardware design. Otherwise no one can provide the correct device tree.
Also, do you have enough knowledge to check the device tree by yourself or not? I am not sure how many things we need to teach you here.
For example, your partial device tree does not matter to me at all. You should dump out the full runtime device tree but not some partial code.
And one last point, it seems you don’t know what to check from dmesg. You can just attach the full log and no need to grep or parse anything from you.
Thank you for your answer!
I’m a novice at device tree/kernel modifying/etc.
Our Wi-Fi connection scheme.
WL_REG_ON_18 connected to the Jetson Nano’s 218 pin.
SD_DAT0_18 — 219 pin.
SD_DAT1_18 — 221 pin.
SD_DAT2_18 — 223 pin.
SD_DAT3_18 — 225 pin.
SD_CMD_18 — 227 pin.
SD_CLK_18 — 229 pin.
My device-tree file:

You need to write a regulator based on your schematic and give that regulator to the vmmc-supply.
For example, WL_REG_ON_18 connected to the Jetson Nano’s 218 pin.
