Is is possible to check if my NXP iMX 8M Cortex A53 + M4 already has Android Things flashed on it?
Or do I need to explicitly flash it on the hardware?
NXP i.MX 8M isn't currently supported by Android Things, only NXP Pico i.MX7D.

Hi I am trying to study PCI device in gem5 system. I am trying to use a ready device from gem5 /dev folder. However, I am not sure how to use the PCI device. Is there anyone can give me some hits about the software driver or hardware configuration. THANKS.
The file is in /gem5/src/dev/pci/CopyEngine.py
The version is 22.
thanks.

example or some hints
I recently purchased an ESP-32 that I use with MicroPython for a web server via Wi-Fi. Everything works very well and I decided to buy 4 more.
But on none of the 4 works when I enable the Wi-Fi interface.
I get this error everytime :
>>> import network
>>> wifi = network.WLAN(network.STA_IF)
>>> wifi.active(True)
Brownout detector was triggered

rst:0xc (SW_CPU_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
I already searched on the web but I found nothing to solve my problem (changing usb cable, switching usb port, resetting and flashing micropython again... nothing works) and that on all of my 4 ESP-32
Do you have any idea of what is the problem and how to solve it ?
Infos:
D1 mini ESP-WROOM-32
MicroPython version: MicroPython v1.11-580-g973f68780
Power : 5V from computer usb
rshell
The problem is that the esp32 is drawing to much power during WiFi transmission, and the voltage drops below a threshold causing brownout. If you are not using the 3.3V pin to drive additional components (or the GPIO pins for LEDs), this should not happen and is due to poor board design. To work around, you could try the following things:
Add a capacitor between 3.3V and GND (as close to the chip as possible)
decrease current draw, e.g. by:
powering external components with 5V from USB
removing LEDs from the board (desolder)
reducing WiFi transmission power (if possible)
reducing the chip frequency e.g. to 40 MHz: machine.freq(40000000)
reduce/disable the brownout threshold (probably requires compilation of micropython)
I hope there is no other topic with the same question but I couldn't find anything related.
Is there a list of supported future devices for ARCore and when those will be probably available? I just got a Huawei Mate10 pro and would love to know when it will be supported.
I'm also up for testing alpha/beta versions.
The ARCore developer previews currently only work with Pixel (XL), Pixel 2 (XL) and Samsung Galaxy S8 devices.
You may want to follow this thread on ARCore's GitHub issues: https://github.com/google-ar/arcore-android-sdk/issues/89
In the meantime, if you want to get started developing for AR and you have an ARKit (iOS) compatible device, you can try Viro React which is a cross-platform AR/VR platform with a write once run everywhere type of a deal.
None can read the future, but you can follow the official list of supported phones as it grows:
https://developers.google.com/ar/discover/
As of 11/march/2018:
Google Pixel
Asus Zenfone AR
LG V30/V30+
OnePlus 5
Samsung Galaxy: S7, S7 edge, S8, S8+, Galaxy 8
I am working on Bluetooth LE using CoreBluetooth on macOS. The app (master) will listen to a characteristic notification from Bluetooth device (slave). And I see that, the macOS only receives 2 packets per second, while the same processing code running on iOS receives about 30 packets per second! I did use other tools for logging and get the same result.
– On iOS, I use the LightBlue Explorer:
– On macOS, I use the Hardware IO tools for Xcode:
My testing devices are:
iOS: iPad Air running iOS 10.2.1
macOS: Macbook pro 2015 running
macOS 10.12.3
So, the bluetooth on macOS is much much slower than iOS, is that true?
Thank you,
Minh
Edited on April 7, 2017:
I think I know where the problem comes from. I tried with Apple Magic Mouse 2 and the bluetooth throughput is about 2KB/s. Then, I configured my slave device with HID services. Now, my MBP can pair with the device and the bluetooth throughput is high. So I think that the unpaired bluetooth signal was filtered by the macOS. Please check this link for the supported profiles.
Google provides the AR developers with Tango platform.
There are two smart phones supporting Tango, ZenFone AR and Lenovo Phab 2 Pro.
If you are a AR developer then which one you gonna choose?
One of them isn't even out yet (Q2 2017) and couldn't be tested by anyone since there were no Tango apps installed when they showed it at CES, so how should one compare? The hardware seems to be stronger, it will be smaller, but the price is still unknown.
