Hello everyone, I’m starting the day with this issue:
I’ve been working on the development of a device for a little over eight months, and now I’m encountering a problem with the eMMC of module 01. This module 01 is in a device that was installed a little over a month ago. Last week, it reported that the operating system was in read-only mode. Today, when I connected it to check, I found the following log output:}

I thought that reinstalling the operating system might fix it, but now it’s reporting problems with the eMMC.
