Q: Why my TF card cannot be recognized? There are some errers such as 'mmc0: error -110 whilst initialising SD card'.


1. Make a backup of /boot/cmdline.txt

sudo cp /boot/cmdline.txt /boot/cmdline.txt.bak 

2. Edit cmdline.txt file

sudo nano /boot/cmdline.txt
#Find this word in the line root=PARTUUID=xxxxxxxx-xx, then replace 'root=PARTUUID=xxxxxxxx-xx' with 'root=/dev/mmcblk0p2'
#(those x'es are placeholders, actually they are letters and numbers)
# Make sure that file is a single line like it was before.

3. Adding sdhci.debug_quirks2=4 to the end of /boot/cmdline.txt. Keep it all on one line.
