USB on MitySOM-5CSx Development Kit
Added by aggelis aggelis over 8 years ago
I bought a miniB to type A connector in order to connect to MitySOM-5CSx Development Kit USB port various slave devices eg webcam , usb drives etc.
When i connect a device to the usb port of Development kit i run dmesg on the terminal and there are no new messages . running dmesg|grep usb before and after i insert eg a usb drive
i get. I
root@node1:~# dmesg|grep usb

Hello,
I see from your defconfig that you are using the 3.12 kernel, is this from our git repository or is this Altera's LTSI kernel?
We do have USB OTG working with the 5CSx, in our 3.16 branch of the kernel if you use the mitysom5csx_devkit_defconfig it should have everything needed to use OTG.

git clone -b socfpga-3.12 git://support.criticallink.com/home/git/linux-socfpga.git
make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- mitysom5csx_devkit_defconfig
then
modified .config file to enable various features among others usb functionality issuing
make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- menuconfig
and finaly
make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- j 4 LOADADDR=0x8000 uImage LOADADDR=0x8000 all
for uimage
and
make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi
to compile modules
then mkdir /tmp/newroot
make modules_install INSTALL_MOD_PATH=/tmp/newroot
then coppied the uImage from arch/arm/boot/uImage to /boot/uImage on sdcard
and modules from /tmp/newroot/3.12.0-00008-g619f7bd to /lib/modules/3.12.0-00008-g619f7bd on sdcard and
booted the system
and if we run uname -a the new kernel is installed
root@node1:~#uname -a
Linux node1 3.12.0-00008-g619f7bd #7 SMP Fri May 20 14:38:02 EEST 2016 armv7l GNU/Linux
the problem is that for our project kernel 3.12 is used and i am not sure we can change that. I will try to diff the
.config files generated with the mitysom5csx_devkit_defconfig for 3.12 and 3.16 to see the USB differences in configuration.
Also i will first try kernel 3.16 to verify usb functionality as a hub (connect a usb flash drive eg or a web cam)
and reply with results.
