Set up as required, but stopped working at the ugit.backup() :

MPY: soft reboot

If only executing ugit.pull_all() :

I've ran into this when there is a directory that has no files within it.

can you add print(dir_item) right after global internal_tree on line 131?

Or do you have an internal folder on the micropython board that does not contain a file?

I thought this issue was fixed but the dir_item should point us in the right direction.

Add print("*NOTE:"+dir_item) , distinction from others.

Ah, if you add ugit.backup to the ignore_files array it should fix this.

It is possible the file is too big or not closed when this is ran. Can you tell me which board you are using and firmware version? I can try to replicate this exactly if possible.

Replicated error with different message:
ESP32-C3 mini v1.19.1

First time I ran it I received this:

MemoryError: memory allocation failed, allocating 13032 bytes)

Executed the following:

  1. Closed upycraftv1.1
  2. Unplugged ESP32 Board and Plugged back in
  3. Restarted REPL through upycraftv1.1

Ran a second time and succeeded.

Known micropython memory persistence issues: REPL environment reboot + Mircopython Board Hard Reboot seems to fix.

gc.collect() works very well with object = none to fix. believe this to be a persistent memory issue that gc.collect() implementation might fix.

Will need some more testing to see if we can replicate after hard board reboot and REPL 'reset'.

Were you able to try again after rebooting your REPL environment and the board?

I have replicated the error but a reset of REPL and Board works every time on my end.

Also note for future. If you make any adjustments to the ugit.py file a board reset and REPL environment reset (if applicable) are almost required.
