Using IIO driver as a Loadable kernel module












0














I want use ti-ads8688 iio driver as a kernel module. I am using Beaglebone Black.



I wrote below Makefile for this work.



obj-m+=ti-ads8688.o

all:

    make -C /lib/modules/$(shell uname -r)/build/ M=$(PWD) modules

clean:

    make -C /lib/modules/$(shell uname -r)/build/ M=$(PWD) clean


ti-ads8688.ko file correctly generated and i load it with insmod command.
But there is not module in iio devices, as you can see in below:



debian@beaglebone:~/work/phase1$ ls /sys/bus/iio/devices/iio:device0

buffer           in_voltage1_raw  in_voltage4_raw  in_voltage7_raw  power          uevent

dev              in_voltage2_raw  in_voltage5_raw  name             scan_elements

in_voltage0_raw  in_voltage3_raw  in_voltage6_raw  of_node          subsystem


am i miss something?
I also add in my devicetree below unit:



adc@0 {

    compatible = "ti,ads8688";

    reg = <0>;

    spi-cpha;

    spi-max-frequency = <100000>;

};

          4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset. My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell". I can't seem to get su access, even after logging in as root (challenge password prompt, and then nothing happens), but shell gives me a proper linux shell.
