Questions[nfc](ubuntu)

I would like the MFOK to find the libnfc-doc file that is in my downloads so I can execute the ./configure "command"---> make --> sudo make install.

I always get the last line (after all others end by : yes) :

-->"checking for libnfc... no"

after typing : ---> "user:Downloads/mfoc-mfoc-O.10.7"

Any help would be greatly appreciated as I'm almost there to get the ACR122U-A9 to copy my RFID badge.

If you know any other workaround on windows/Mac OS to clone it without having to get to this hack it'll be even better !

Stay safe & thanks.

Cheers.

nfc-list & nfc-scan-device both says:

No NFC device found.

usb-devices lists it as:

I:  If#=0x1 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage

The usb-storage part works in windows, and includes a software for using it in windows. But in Ubuntu it can't be mounted, running fsck.vfat /dev/sdb shows:

fsck.fat 4.1 (2017-01-24)
Read 512 bytes at 0:Input/output error

Where can I find hint on how to use it? It comes in 2 models, NFC-PM3 & NFC-PM5, where 5 supports more types/freqenses. But googeling them just gives alot of ProxyMark PM3 devices :-(

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?

After installing according to How to install MFOC

I am currently using ubuntu on VM oracle

I connected ACR122U card reader and ran mfoc -O

The reader's indicator is lit so I think the reader is working fine

pcsc_scan is able to detect the reader and card

$ mfoc -O mycard.mfd
info    libnfc.config    Unable to open file: /etc/nfc/libnfc.conf
debug    libnfc.config    Unable to open directory: /etc/nfc/devices.d

debug    libnfc.general    0 device(s) defined by user
No NFC device found.

does anyone know if NFC Host Card Emulation is supported on Ubuntu natively? if not, we would like to supply the patch for it.
