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 '18 at 17:59
