4.2 How to mount the root FS on a SD card
The on-board flash is a raw flash. It is with limited write cycles (about 100,000 times) and without
wear leveling mechanism and atomic write operation. So it is not recommended to write user
data to the on-board flash frequently. Besides, its storage is also limited to 32MB, the spare space
might not be sufficient for storing lots of user data and software packages. As a result, it is
recommended to mount the root FS on a SD card for getting more and reliable storage.
Steps:
Below are the steps for making this work. For details, please refer to the OpenWrt WiKi for
