After further debugging the issue, I found that after powering on, when I
first successfully download the file "1.txt", I can see it when I execute "ls
/mnt/w25a/". However, when I execute "ls /mnt/w25a/" for the second time, the
"1.txt" file is no longer present. I also tested with "cat /mnt/w25a/" and "cd
/mnt/w25a/", and the same phenomenon occurs. I traced the execution and found
that there is a point where the node of the file is freed. It seems that after
the first "ls" command, the node of the file is freed, causing subsequent "ls"
commands to not be able to see "1.txt". However, I didn't fully understand the
logic and reason behind this. Do any developers in the community know why this
is happening?
