hi, I have nand memory used for 88%, it starts from memory and used by 124.0M 0% /dev/shm, if I install other software packages could I have problems? Is this partition automatically resized by the system?
thanks for your help

Hello,

/dev/shm is a temporary memory file system (tmpfs), and its contents will be cleared when the system is restarted. It is mounted in memory, not on the storage device. Therefore, you cannot allocate space in /dev/shm directly to the / file system (ubi0:rootfs).

If your / file system is full, you may want to consider freeing up some space, deleting unnecessary files or moving files to another location to make room.

thanks for your answer.
how can I do ?
I'm supposed to have SPI NAND FLASH (256MB pico max) but it seems like I've only taken up half the memory 100.7M?
ubi0:rootfs 100.7M 88.6M 12.1M 88% /

what am I missing?

The image burned from the Google Drive link shows a total memory of approximately 186 MB. Additionally, if the camera or RKNN inference is not used, it is possible to free up operational memory by modifying it from 66 MB to 1 MB.
