Sainsmart 3.2" LCD screen and Kali Linux

Former Member

Hello all,

 

 

I have a SainSmart LCD that can be found here http://www.sainsmart.com/sainsmart-3-2-tft-lcd-module-320-240-touch-screen-display-for-raspberry-pi.html and a Raspberry Pi 3 Model B that is running the version of Kali Linux found here: https://www.offensive-security.com/kali-linux-arm-images/ and labeled "RaspberryPi w/TFT"

 

 

When I plug in the Pi nothing appears on my LCD screen, and when I plug in an HDMI a brightly colored rainbow rectangle appears on my screen. Plugging in a keyboard and attempting to run commands does not seem to do anything. I also am unable to ssh into the Pi using this version of Kali Linux, as the Pi does not show up on my network. I have it connected via ethernet. Due to the Pi not appearing on the network I suspect that this distro is somehow crashing when I attempt to boot it.

 

 

I attempted to use a different version of Kali Linux (The one labeled RaspberryPi 2/3 from the link above) and was able to get it working on my Pi, with the display functioning through HDMI and ssh fully functional. However, I was unable to get the LCD screen to function using that version of Kali. I also tried using both Rasbian Jessie and Raspbian Jessie lite along with a number of tutorials for the LCD screen that I found online, still with no luck.

 

 

Does anyone have any suggestions on how to get this screen working? I would prefer to use Kali, but if I need to use Raspbian Jessie and install pentesting tools as I go that would be fine as well. The only thing I need the screen to display is a command line interface.

    Hi,

     

    The colored square usually means "low voltage", i.e. the power supply and/or USB cable needs changing.

    No idea how to get your screen running though, are you sure it is supported on the Pi 3 and latest builds?

    Have Sainsmart confirmed that it works on the Pi 3? (a lot of vendors do not provide drivers or test,

    so you might be on your own or have to find someone else with the same display).

    Hi Shabaz,

     

    Thanks for the quick reply. Sainsmart specifies that a 5V/2A power supply should be sufficient to power the LCD and the Pi. I am using a power supply with exactly those specs but I will try something with a little more amperage when I return home. I have also reached out to the manufacturer to see if this is compatible with the Pi 3. I could always pick up a Pi 2 if need be.
