Nanopi M1 plus boot error

[franksmith]

Hello,
I’m new to the Nanopi M1 Plus development board. I followed the instructions on FriendlyARM's wiki page. I loaded the image from my Ubuntu OS and connected the device to my PC. The blue LED is blinking normally. I used PuTTY to view the logs, and during booting, it shows:

Hello I am new to Nanopi m1 plus development board. I followed the instruction as on friendlyarm's wiki page. I loaded the image from my Ubuntu OS and connected my device to the pc. The blue led was blinking normally. I used Putty to view the logs. While booting it is showing:

I uploaded nanopi-m1-plus_friendlycore-xenial_3.4.y_YYYYMMDD.img.zip image.

What is the issue and how can it be resolved?

Hi!
Based on the log you posted, the error Bad magic number in super-block usually means that the root filesystem on your SD card is corrupted or not properly written.
Here’s what I suggest:

Verify the image file: Make sure the .img.zip file downloaded correctly. Check its MD5 or SHA256 checksum if available.

Re-flash the SD card: Use a reliable tool like Etcher or dd to write the image to your SD card. Sometimes the write process fails silently.

Use a different SD card: Some cheaper or older SD cards can cause filesystem corruption. Try using a Class 10 or UHS-I card.

Check partitioning: Ensure the image was properly extracted and written to the SD card; the root filesystem (/dev/mmcblk0p2) should exist and be mountable.

After re-flashing, try booting again. If the problem persists, it might be a bad image build or incompatible SD card.

Hi, I ran into a very similar issue when I first started with my NanoPi board.

That error usually means the root filesystem on the SD card is either corrupted or wasn’t written correctly, so the system can’t find /sbin/init.

A few things I’d suggest checking:

Make sure the image was fully extracted before flashing (don’t write the .zip directly).
Re-flash the SD card using a reliable tool like dd or Etcher, and double-check there are no errors during the write.
Try a different SD card if possible — I’ve had cards that seemed fine but caused exactly this “bad magic number / no init found” issue.
Also ensure the image matches the board (M1 vs M1 Plus can matter).

In my case, it turned out to be a bad flash on the SD card, and rewriting it fixed everything.

Quick question: did you verify the image checksum or try another SD card already? That would help narrow it down.

This error usually means your SD card image is not written correctly or is corrupted.

The important messages:

“Bad magic number”
“Couldn't find valid filesystem”
“No init found”

In simple terms: the system can’t read the files it needs to start, so it crashes and reboots.

What you should do:

1. Reflash the image

Extract the .img file from the zip
Flash it again using a tool like Balena Etcher
Make sure the process finishes completely

2. Try another SD card

Some SD cards cause this problem
Use a good quality Class 10 card if possible

3. Re-download the image

Your download might be corrupted

Most of the time, simply flashing the image again or using a different SD card fixes it.
