Hello.
I am trying to bring up TI SDIO Wifi module on Zedboard
I am using this adaptor
http://zedboard.org/product/wilink-8-adaptor
with WL1837MODCOM8I (from TI) on zedboard
I have built the hardware platform explained in this tutorial
http://zedboard.org/sites/default/files/documentations/GSG-AES-PMOD-WILINK8-G-v1_6.pdf
I use Vivado 2015.2 and kernel 3.17
In addition I downloaded the script files provided (for the build with latest ArchiTech SDK) The SDK 2.1.0 Yocto build includes Wilink8 R8.5 driver support.
During power up shows up next error:
request_irq() failed
and wlcore doesn't loaded
In device tree next lines were added:
wlcore {
compatible = "wlcore";
interrupt-parent = <0x3>;
irq = <0x0>;
platform-quirks = <0x1>;
board-ref-clock = <0x4>;
};
fixedregulator@1 {
compatible = "regulator-fixed";
regulator-name = "wlan-en-regulator";
regulator-min-microvolt = <0x325aa0>;
regulator-max-microvolt = <0x325aa0>;
gpio = <0x4 0x9 0x4>;
startup-delay-us = <0x11170>;
enable-active-high;
linux,phandle = <0x6>;
phandle = <0x6>;
};
I am wondering what is going wrong in my setting that Wifi platform cannot be configured and set up as an Wifi interface
