I just bought the Kuman 3.5 inch touchscreen display for the Raspberry pi, and I installed all of the drivers correctly using this link: How can I install the KUMAN 3.5 inch-display? After I finished installing them, the system rebooted, but i got an error saying:

---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)

and I don't know how to fix it. People were saying

What I found was that the root file setting in the "cmdline.txt" entry that the >driver tries to install was incompatible with the setting in the original "/boot/cmdline.txt". E.g. The original cmdline.txt has "root=/dev/mmcblk0p7" where the driver tries to overwrite it has "root=/dev/mmcblk0p2". After changing "mmcblk0p2" to "mmcblk0p7", the system boots up and the LCD screen works


Download driver: http://www.waveshare.com/w/upload/3/3d/LCD-show-160811.tar.gz

Add to /boot/config.txt

hdmi_cvt 800 480 60 6 0 0 0

Install: tar xzvf /boot/LCD-show-YYMMDD.tar.gz; cd LCD-show/; ./LCD35-show

Touch function will work after restart...

They were all mentioning various .txt files, so I tried looking in my pi's microSD card, but nothing was there. I do not want to flash a ROM to it, because my computer isn't working well and I don't have that much time. Is there any quick fix to this problem? Thanks!

    nothing was there ... do you mean that the SD card is blank?

  • No, I have the raspbian installation files, and a bunch of backup files, but I can't locate the files from github. My raspi did say that the cloning completed successfully. Is it something to do with partitions that my computer can't read? Mar 2, 2018 at 17:59
