Dear community members,
We are working in the development of a robot autonomous control system running inside an Intel Edison, which -in turn- runs in a PixHawk automatic pilot module . This system uses ROS (Robot Operating System) and therefore we had to install Ubilinux. Our system requires being connected with a 360-degree laser (RPLIDAR-360) that sends data through a serial channel, so we are trying to get laser's data through USB-to-UART adapter (Silicon lab's CP2102) (the PixHawk only has a USB available for data transfer).
In summary, the laser is connected to the USB2UART adapter, and the adapter is connected to Edison's serial port.
However, we are stuck with some kind of driver issue. When tracing 'dmesg' the device is detected (idVendor=10c4, idProduct=ea60):

But no /dev/ttyUSBX device is created, and there are no error messages about missing Drivers or configuration failures.
We are using Ubilinux 3, which reports the following with the 'uname' command:
** 3.10.17-yocto-standard-r2
And the following is the listing of the installed drivers:
usb
/lib/modules/3.10.17-yocto-standard-r2/kernel/drivers/media/usb:
/lib/modules/3.10.17-yocto-standard-r2/kernel/drivers/media/usb/gspca:

usb_f_acm.ko
/lib/modules/3.10.17-yocto-standard-r2/kernel/drivers/usb/serial:
usb_wwan.ko
Does anyone has had a similar configuration and managed to make work a CP2102 adapter?
As a last resort, we are trying to compile and install the driver by ourselves, using this reference: [url=https://askubuntu.com/questions/941594/installing-cp210x-driver]Installing CP210x Driver?Installing CP210x Driver? - Ask Ubuntu[/url]
The 'make' process crashes due to a lack of headers. We were unable to download the headers through APT, but at the end, we managed to compile the '.ko' module by downloading the headers manually from a Website.
However, after doing:
insmod cp210x.ko
We got:
Insmod: ERROR: could not insert module cp210x.ko: Invalid module format
So, at this point we have several questions... any advice about any of them would be really appreciated:
Does anybody know how to install the Kernel headers in Ubilinux - 3.10.17?
What is the official procedure to upgrade the Kernel in Ubilinux?, we already have ROS working on the board... do you think a kernel upgrade could mess our ROS configuration?
In general, do you have any successful experience in the configuration of a cp210x device?
Thanks in advance,
Héctor
The driver for cp2102 already exist in kernel, no need of extra efforts. Just use the correct udev rule file (not present by default in linux distro). An example is here. With this file /dev/ttyUSBX will be created.

I am trying to run Linux (buildroot) + baremetal app on Xen.
Xen boots great and buildroot is ok on the first CPU.
My problem is the baremetal application.
The baremetal app is generated by Vitis (my A53 is in the FPGA).
This is the simplest example application : just an hello world and exit.
I am able to boot directly on this app using the jtag but when I try to run the baremetal app in Xen the app just hand and doesn't print anything.
My configurations :
FILE : xen.cfg
name = "test"
kernel = "/opt/baremetal_app.bin"
memory = 8
vcpus = 1
cpus = [1]
iomem = [ "0xff010,1" ] # UART1
Xen command line :
console=dtuart dtuart=serial0 dom0_mem=1G bootscrub=0 maxcpus=1 timer_slop=0
dom0 command line :
console=hvc0 earlycon=xen earlyprintk=xen maxcpus=1 clk_ignore_unused root=/dev/mmcblk0p2
Vitis is configured to include the hypervisor_guest the in binary.
I already tried to change the psu_ddr_0_MEM_0 to 0x40000000, len 100000.
When I run the command "xl create xen.cfg", the system print "Parsing config from xen.cfg" and returns. I see my app test in "xl list".
The uart1 doesn't print anything and the "xl console test" neither.
With "xl top" my app test seems to use 100% of the cpu.
Any idea ?
I'm trying to run ElectronJS app to Buildroot-based Operating System for a vehicle instrument. The SBC is Raspberry Pi 4B and target packages are included based on Debian's dependencies list. Then after I run the app, it throws this message:

Keep in mind that glxgears and glxinfo are working perfectly. The frame rate is around 198 FPS. Thus, GPU supposed to not be blamed.
I am pretty sure something wrong with ALSA libraries or DBUS, perhaps anyone experiencing same problem? Thanks!
Adding { frame: false, fullscreen: true } in the electron BrowserWindow constructor options make it work.

I'm trying to build a VM for model training in Azure. I found this Data Science Virtual Machine for Linux (Ubuntu) VM which seems to be a suitable candidate.
Unfortunately, when I spun up the VM and installed the caffe prerequisites I wasn't able to run the tests. I'm getting the following error on make runtest (make all and make test were completed without errors):

Is it possible to spin up a virtual machine in Azure suitable for GPU enabled machine learning using caffe?
All the details about the VM here
The Data Science Virtual Machine (DSVM) for Ubuntu already has Caffe installed in /opt/caffe. To use it on a GPU, create a VM with a K80 GPU by choosing the one of the NC sizes. (Be sure to choose HDD as the storage type, or the NC sizes will not appear.) Caffe will then be available out of the box.
Also note that PyCaffe is available. At a terminal:
source activate root
And python will then have PyCaffe available.
