xjm's questions

I need to install ofono, so I cloned this ofono repository and did autoreconf -fi and ./configure in the directory. But when I am running make or sudo make install I am encountering the following error:

make[1]: *** No rule to make target 'ell/util.c' needed by 'ell/util.lo' Stop.
Makefile:2093: recipe for target 'all' failed
make: *** [all] Error 2

I checked the folders and ell/util.c exists, but ell/util.lo does not. I also tested on another PC and I'm also getting the same error. Are there any dependencies or steps I missed?

I would like to check my laptop's sensor (e.g. simple device orientation sensor, gyrometer, hinge, etc). I came across the sensor diagnostic tool for Windows 10 but I don't know if it has any equivalents for Ubuntu and I couldn't seem to find any.

Any recommendations?

I need to install a driver on Ubuntu with this guide but i'm having some trouble with some parts of it.

Below is the definition to be added to the platform definition file:

I'm using Ubuntu 18.04 and dug around where the platform data file might be located and i saw /lib/modules/$(uname -r)/build/include/linux/platform_data/nxp-nci.h. Is this the correct platform definition file?

pn5xx_i2c.h must be included in the platform definition file

since there was a part of the instruction that says "pn5xx_i2c.h file must be copied to include/linux kernel source sub-folder", to do this part i just referenced pn5xx_i2c.h in the nxp-nci.h file by adding:

#include<linux/pn5xx_i2c.h>

Then the declared nfc_board_info structure must be added to the platform using dedicated procedure (platform specific).

From my understanding, I'd have to edit this part of the code:

static struct i2c_board_info __initdata nfc_board_info[] = {
{
I2C_BOARD_INFO("pn547", 0x28),
.platform_data = &nfc_pdata,
},
};

that I added to the nxp-nci.h file and change 0x28 to whatever my platform is.

Assuming I did this part correctly, there should be a /dev/pn544 device node created which i can check by running cd /dev/ and ls. However, there is no pn544 device listed in my /dev folder so there must have been something wrong in one of the processes.

I also tried using device tree as was suggested here but I did not find any .dts files from the /lib/modules/$(uname -r)/build/arch/arm/boot/dts folder. I was also told that it might not be applicable because my PC is not an ARM-based Linux device.

Did I miss a process or could it be an NFC compatibility issue with Ubuntu?

I inserted a sim card in the sim card slot of my laptop and was expecting the mobile broadband option to appear on the system menu, but it doesn't. I have a Fibocom L860 and WWAN is also enabled via bios so I'm thinking that it should work. As far as I know, Fibocom L860 should be supported in Ubuntu.

I checked by running mmcli -L on the terminal and it says that there were no modems found. I also tried to run sudo modem-manager.mmcli -L, but I keep getting error: couldn't get bus: Could not connect: Permission denied. I tried installing a modem manager gui, but it's still not able to recognize my sim card.

I tried solving my problem using this solution but there's no CD/DVD drive option appearing, so I couldn't proceed with it.

I am not sure why this problem is happening. Is there a way to check if the problem is with the sim card, the sim card slot, or anything else?

Edit: I switched the OS to Windows to check if it was a hardware problem, but my sim card was easily recognized and I was able to use it to access the internet.

Switching back to Ubuntu, I entered nm-connection-editor on the terminal and added a mobile broadband connection for my sim card. I also tried running mobile broadband by entering sudo service mobile-broadband-connection start, but I still cannot access the Internet, and mobile broadband option still isn't appearing in the system menu either.

What could be causing this problem?
