Hi,

after upgrading with sysupgrade some weird files have appeared in the / directory.
We've tried with old images that worked before and the files stayed there, not sure if they have the same names. The only difference is that we are working with brand new carambolas. We also tried flash erase from uboot and reflashing with tftp and still the same.
Also tried with another device (also new) with the same results.
Those "files" can be erased with rm but they will appear after a reset.

Any ideas?
Thanks in advance
