How to enable ftdi module on MX53 QSB linux (i.MX53 connect to arduino Mega 328)

[TKs]

I am running a java6 which sends data to a robotic kit which has the arduino mega328 as a controller.

I have tested arduino uno and it is recogized by i.MX53 and my java programm sends data.

But the arduino mega328 is not detected.

I found out that I have to enable a kernel module named ftdi_sio from the kernel.

So I downloaded this image (https://github.com/lgeek/linux-2.6.35.3-imx53)

copied to /usr/src/ and renamed it to "linux". I also linked

"linux-2.6.35.3-1129" and "linux-2.6.35.3-1129-g691c09a" to "linux"

using "make a link option" in nautilus which I started with sudo sh

nautilus.

Next I copied my .config file:

cp /proc/config.gz /usr/src/linux

and in /usr/src/linux I unzipped it and rename it to .config

sudo make menuconfig

Navigated

to Drivers -> USB Support -> USB Serial Converter Support and

chose 'M' for the USB FTDI Single Port Serial Driver

sudo make modules

sudo make prepare

sudo make modules_prepare

sudo cp drivers/usb/serial/ftdi_sio.ko /lib/modules/$(uname -r)/kernel

sudo depmod -a

But dmesg shows

ftdi_sio: no symbol version for module_layout

after a rebuild:

make

doing the whole process again I get:

usb wakeup is here

ehci_fsl_bus_resume, Host 1

[art · Accepted solution]

Seems that you didn't enable the generic usbserial driver, that is required in addition to ftdi_sio driver. Also, you may have to use the kernel [*] support for the drivers rather than the module [M] one.

Please refer to the following community thread:

It seems to be helpful in that.

Have a great day,

Thank you very much for your answer!

I used this guide:

https://eewiki.net/display/linuxonarm/i.MX53+Quick+Start

TIP: in step

export DISK=/dev/mmcblk0        make sure to type yours device location

       and in step:

export kernel_version=4.X.Y-Z   this kernel version must be the kernel version of MX53.


Well I installed Ubuntu 14.04 LTS, ftdi driver works like a charm but my second usb port does not work at all and the upper USB port can not detect USB sticks.

Keyboard works.

Any suggestions??

EDIT: doing the following I can read my usb-data

file -s /dev/sdb

mount -t auto /dev/sdb /mnt

How to mount automatic?
