I am trying to use adreno GPU in qualcomm RB5 in ubuntu environment by using pyopencl. Does anyone have experience of similar project through pyopencl?
import pyopencl as cl
Create a PyOpenCL context
ctx = cl.create_some_context()
Query the available OpenCL devices on the system
devices = ctx.devices
Iterate over the devices and print information about each one
for device in devices:
print("Device name:", device.name)
print("Device type:", cl.device_type.to_string(device.type)
if device.name.startswith("Adreno"):
print("Adreno GPU is available.")

I am trying to use serial download with the google coral dev board with uuu, imx_usb_loader, or similar. I have a working uboot, but it does not appear to have the necessary usb functionality built into the spl because I get this error.
U-Boot SPL 2022.04 (Sep 01 2022 - 02:38:53 -0500)

I have attempted to add spl_board_boot_device() to my common/spl/spl.c to no avail. I have also tried a great many other config options. Also no change, but somtimes there are compile errors... And I have made sure that the usb entries in the uboot dtsi are marked as "okay". I am not sure where to go from here. I am mainly using imx-uboot 2022.04 and mainline 2022.07
I use DELL Precision 3541.
After rebooting my laptop, I am getting "No Wifi adaptor found". So I tried few solutions mentioned in stackoverflow. But when I hit sudo lshw -C network
I am getting this in response

There is no logical name for my wifi adaptor.
Is there any way I can enable the wifi adaptor on my laptop?
I tried something random. Dont know how it worked for me. Just followed the steps.
1.Restarted my Laptop.
2.Entered BOIS setup (F12).
3.Then inside the wireless section, I completely disabled WLAN.
4.When it booted up successfully, Restarted Laptop again.
5.Entered BOIS setup and enabled the WLAN.
Finally, when the laptop turned on, everything was working fine again.
In my case I installed ubuntu 20.04 and wifi was not working, message was same as "No wifi adaptor found".
I had onboard wifi adaptor.
Using command sudo lshw -C network, I got
*-network
description: Wireless interface
product: Wi-Fi 6 AX200
vendor: Intel Corporation
I knew that my wifi adaptor is of Intel® and now I found that Wi-Fi 6 AX200 160MHz is the actual adaptor.
After doing hours of googling, I went on intel official site and found this link Linux* Support for Intel® Wireless Adapters
I found that my adaptor was listed there under Intel® Wi-Fi 6 AX200 160MHz
I downloaded iwlwifi-cc-46.3cfab8da.0.tgz and extracted it under the directory /lib/firmware as mentioned on intel site.
wooooooooooooo, ubuntu was able to detect the adaptor and my wifi connections were listed under wifi settings.
You may need to restart the system, though in my case it worked as soon as I extracted the files in /lib/firmware.
If I have Android phone connected via USB, how do I know the commands I can send via USB to get Information like
core temperature of the device,
version of android,
power consumption details, etc.
Can I then use ADB logs, command to interact with Android mobile. Please may i know the process apart from commands if I have to send commands via ADB.
To get information from an android device, you can always use the following tools.
Use utilities like dumpsys or getprop.
Query from /sys/ or /proc/.
Eventually all utilities, fetch information from /proc or /sys, so you can directly investigate into these.
You could use dumpsys tools to get information:
Core temperature of the device
I'm not sure, what exactly do you mean by core temperature of the device.
Temperature of Device: Note
$ adb shell cat /sys/class/thermal/thermal_zone0/temp
37
Temperature of Battery:
$ adb shell cat /sys/class/power_supply/battery/device/power_supply/battery/temp
285
or
$ adb shell dumpsys battery
Current Battery Service state:
AC powered: false
USB powered: true
Wireless powered: false
status: 2
health: 2
present: true
level: 15
scale: 100
voltage: 3768
current now: -357254
temperature: 285 # <---- Temparature.
technology: Li-ion
Version of android
$ getprop ro.build.version.release
4.4.4 #<--- Android Kitkat 4.4.4
I'm not completely sure how you can get exact information:
You could start with,
$ adb shell dumpsys power
POWER MANAGER (dumpsys power)
Power Manager State:
....
Note: Results on a Linux System.
$ acpi -t # <--- apci power utility/tool.
Thermal 0: ok, 29.8 degrees C
Thermal 1: ok, 27.8 degrees C
$ cat /sys/class/thermal/thermal_zone0/temp
27800
I want this to be executed every 50 ms ?
You could write a script with above commands, that queries every 50ms.
Set-up ADB on Windows ?
A quick Google search should help you out.
Set Up Android ADB On Windows
To make proper use of Dumpsys,
See What's the Android ADB shell "dumpsys" tool and what are its benefits?

Getprop : Android ADB commands to get the device properties
I hope this should give you a good start.
You will get the Android device properties using getprop command.
Please go through this blog .Here I am listing some of the major ADB commands. Feel free to ask doubts regarding these commands.
I am trying to port eCos on an i386 PC.
I have downloaded prebuilt redboot.bin from
http://ecos.sourceware.org/ecos/boards/redbootbins/x86pc/
I boot it onto usb disk, using
dd conv=sync if/redboot.bin of=/dev/sdb1
After booting target from usb, I get "IA2!" string on the target monitor always, and on serial port on 38400 8n1 configurations, I receive nothing.
I tried using i386-elf-gdb, but it is not able to connect to the target and starts printing "Ignoring error packet, Continuing..."
I also tried to build redboot using configtool for i386, but it is only able to build library, when I try Tests, It gives ERROR: multiple definition of cyg_start()
I am very new to eCos, and I don't know what I am doing wrong!!.
Ok, I figured out how to boot Redboot on a target i386 pc with RealteK RTL8139 ehternet card.
install grub on usb stick,
mkdir /mnt/USB && mount /dev/sdx1 /mnt/USB
grub-install --force --no-floppy --boot-directory=/mnt/USB/boot /dev/sdx
Build Redboot using ecosconfig, make sure the number of pci bus are less than 8 or more, if more, then need to increase the pci bus range from from 8 inside pci.h, I had my realtek ethernet card on bus 10 dev 10, I had to increase the bus to 11, so that redboot finds realtek card on bootup.
ecosconfig new pc redboot
configtool ecos.ecc
add common ethernet support
Build Library
copy redboot.elf on usb.
on grub startup menu,
insmod multiboot
multiboot /redboot.elf
boot
Thats it, redboot will use BOOTP and provide IP Address, then I can test redboot commands like ip_address, reset, ping, version etc.
I've been looking into Ubuntu Touch.
So I installed ubuntu on a Nexus 10 following the instructions here
I built the sample app following the instructions here
So now I have a device running ubuntu touch and an application, how do I put the application on the device?
You can use Qt Creator: Connect your Ubuntu Touch Device through usb open your project and simply press Ctrl+F12.
This works only if you have once installed ssh-server on the device.
Alternatively you can do it manually. Copy the necessary files (*.qml and *.desktop) to the device and start the application via ssh
qmlscene --desktop_file_hint=/usr/share/applications/qmlscene.desktop YourApp.qml
Source
Remember, this is all beta and if you are not a developer then you won't have much use for Ubuntu Touch at this stage. Eventually, Ubuntu Touch will have its own app store where it will be much easier to download apps and install them on your device.
If you are using the sdk provided by Ubuntu, then all you have to do is go:
Build -> Ubuntu Touch -> Install Application on Device
This will actually install the App instead of just running it. Now you can bring your prototypes with you =)
