Hello, I was working on Azurewave CM358 WIFI bluetooth module. It consist of NXP chip 88W8987. I am trying to Interface it with Nano on my custom carrier board. I already successfully interface with this module with TX2 NX. Following is the configuration in dtsi, sdhci@3440000 { status = “ok…

try bus-width = <0x4> or uhs-mask = <0x10> for SDR104

Hello, Today I checked the Nano SDIO port functionality. I can able to interface with SD card. But still I am not able to detect WIFI module with port. Please guide me on this.

Hello, Any update on the query.

The phandles are probably different. You need to compare the device trees for TX2 NX and Nano to get the right values for each node.

Hello, Thanks a lot for reply. I will check phandle for both the cases. There is one more thing I observed that when I was interfacing WIFI module with TX2NX I am getting continueous clock of approx. 45MHz. [TX2 CLK] But with Nano I am getting discontinuous clock [NANO CLK] I m missing some…

Sorry I don’t know. Did you try changing the phandles?

Hello, Thanks a lot reply. I tried to search something on phandle. But I cant find any reference on this. Still I am searching on that. One more thing I want mention here that with same device tree changes I can successfully communicate with SD card this time this phandles configuration work prop…
