Trying to boot a PocketBeagle 2 Industrial from a 256GB sandisk uSD card fails with a panic,
can’t find init.

try reflashing, this looks like ext4 corruption..

OK - will try but I made a few of these 256GB uSD and they all fail the
same way. I didn’t think of re-flashing…

I tried re-flashing - the GUI puts up a “Failed” notice.

Repeatable.

Can you take a screenshot of which image and share the bb-imager log?

I will retry today and send logs. Thanks for the follow-up.

“corrupt” in sense I suppose, I will have to return these useless Sandisk uSDs.
They seem to have their controller code in a hidden partition that the Beagle programmer
writes on. After that, they become raw 64GB locked volumes.

The uSD/SD Association “format any SD the right way” app says “this is broken”.

I will order other uSDs now.

Thanks for the diagnostic help!

FYI

with image: pocketbeagle2-debian-13.7-iot-v6.18-k3-arm64-2026-09-20-10gb

Sandisk 512GB A2 U3 works (had to power cycle it a few times on first boot)

Samsung 128 EVO works

I am not sure these are genuine.

I will keep trying to find out what’s up here.
Your results are encouraging.
