Solving Storage Space Issues on Aetina Evaluation System

Use a 32 GB or larger card

We recommend using at least a 32 GB microSD card with the Aetina Evaluation System, because the onboard storage is limited.

Check available space​

First, check how much space is left on the host:

df -h /home/firefly/.cache/axelera/data
Filesystem      Size  Used Avail Use% Mounted on
/dev/root        14G   11G  2.2G  84% /

Clear the data cache​

List what is in the Axelera data cache:

ls -l /home/firefly/.cache/axelera/data
total 8
drwxrwxr-x 7 firefly firefly 4096 Mar  3 19:37 coco
drwxrwxr-x 2 firefly firefly 4096 Mar  5 14:16 ImageNet

Then remove it:

rm -rf /home/firefly/.cache/axelera/data
What this removes

This only clears downloaded datasets and cached artifacts. The SDK re-downloads what it needs the next time you run a pipeline.

Move the cache to the SD card​

Find your SD card mount point. In this example it is /axelera (partition mmcblk1p1):

lsblk -f
NAME         FSTYPE FSVER LABEL       UUID                                 FSAVAIL FSUSE% MOUNTPOINTS

Create a directory for the data on the SD card:

mkdir -p /axelera/axelera_data

Point the cache folder to the new location with a symlink:

ln -s /axelera/axelera_data /home/firefly/.cache/axelera/data

Verify the symlink:

ls -l /home/firefly/.cache/axelera/data
lrwxrwxrwx 1 firefly firefly 21 Mar  5 14:49 /home/firefly/.cache/axelera/data -> /axelera/axelera_data
