I have a FT2232H-56Q Mini Module and can't detect GPIOs with gpiodetect using Ubuntu 20.04 and Kernel 5.4.
Seems to be similar to this but it should actually be fixed in Kernel 5.4.
Any help would be appreciated

we are trying to run our app that integrates jsbrowser on Raspbian 4.4.50-v7+ (raspberry pi 3) and get the message that the operating system is not installed.
we integrated the linux 32 and 64 bit libraries.
how to get jxbrowser running on Raspbian ?
The Raspberry Pi is an ARM-based platform. According to JxBrowser system requirements this platform is not supported at the moment by the JxBrowser library.
I have a waveshare 3.5 inch touch LCD display and I m trying to get it working with the latest version of Raspbian A.K.A Raspbian Jessie. I followed futurice.com 's tutorial on getting it to work (tutorial is titled I'd like some LCD on my pi) and it worked on Raspbian Wheezy just fine. All I get now is a blank white screen. All help is greatly appreciated! (I must use the official Raspbian Jessie image without NOOBS from the Raspberry pi website.) I have a Raspberry Pi 2 Mobel B +.
From the product page:
Why the LCD doesn't work with my Raspbian? To use the LCD with the
Raspberry Pi official image, driver should be installed first. Please
refer to the user manual. However, for the first testing, you may want
to use our provided image directly. Why the LCD still doesn't work
with the Waveshare provided image? Make sure the hardware connection
is correct and connects fine. Make sure the image in TF card is burnt
correctly. The PWR will keep on and the ACT will keep blinking when
the Raspberry Pi starts up successfully, in case both of the two LEDs
keep on, it is possible that the image was burnt incorrectly OR the TF
card was in bad contact. Which power supply should I use? It is
strongly recommended to use a stand-alone 5V/2A power adapter, because
the PC's USB port might doesn't have enough power to support the Pi
and LCD. For more info, please check the wiki page
You can find more info on their wiki.
It sounds like you either need to use their Raspian image, or install the driver for this display on your existing Raspian install:
wget http://www.waveshare.net/w/upload/7/73/LCD-show.tar.gz
tar xvf LCD-show.tar.gz
cd LCD-show/
sudo ./LCD35-show
I am getting the following error when running the emulator like this:
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please Ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAX kernel module is not installed!
And here I use AMD processors, is there any solution ?
Intel HAXM only runs on certain Intel processors that support Virtualization and ND bit. There are other alternative emulators to the built in one - like GenyMotion
to run the emulator in the new Android Develop Studio, I need to turn on the virtualization support (VT-x) on my guest windows 7 running in KVM, which in turn is on RHEL6.
Google shows we need vmx & vme in the guest processor definition, which I have them as 'require' from dumpxml. But in Android Develop Studio in my guest win7, it still complains about missing virtualization support.
Cannot launch AVD in emulator.
Output:
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAX kernel module is not installed!
I then download 'haxm-windows_r05' and run 'intelhaxm.exe' to install it, with error:
VT not supported
This computer does not support Intel Virtualization Technology (VT-x). HAXM cannot be installed.
Please refer to the Intel HAXM documentation for more information.
In summary, my guest (windows 7) on KVM (running on RHEL 6) can not turn on Intel Virtualization Technology (VT-x).
Thanks for any help

Unfortunately, RHEL6 lacks support for Nested Virtualization. RHEL7 does but it's still very premature and new changes keep getting added. Your best bet is to install the current upstream kernel. To enable Nested Virtualization, load kvm_intel with "modprobe kvm_intel nested=1".
And ofcourse, you need to advertise vmx in your cpu definition.
I would like to use some parallel computing function using the GPU. I tried to use gpuarray function but I have got the following error message:
There is a problem with the CUDA driver or with this GPU device. Be
sure that you have a supported GPU and that the latest driver is
installed.
Caused by:
The CUDA driver could not be loaded.
The library name used was
'/usr/local/cuda/lib/libcuda.dylib'.
The error was:
dlopen(/usr/local/cuda/lib/libcuda.dylib, 10): image not found
Therefore I would like to know how to install, load CUDA driver and set Matlab to do GPU processing on my Apple Macbook Pro Retina running OS X 10.10 Yosemite ?
My GPU is a NVidia GeForce 750M. My Macbook Pro Retina (15") is from the late 2013 generation.
I'm running Matlab 2014b
Thank you for your help and support,
Best,
Adrien
EDIT: thank you Robert C., I followed these instructions and Matlab with GPU seems to work fine now :)
I succeeded following the instructions in the CUDA getting started guide for Mac OS thanks to Robert.
