Nucleo-F411RE file UPLOAD/DOWNLOAD limit ??

[valoni]

did Nucleo-F411RE have any file UPLOAD/DOWNLOAD limit

because i have latest firmware NUCLEO_F411RE-20191220-v1.12.dfu

and tried some code to upload and i always got message download false4



can someone help me about this code to see how to run it
about memory it show me about 95100 bytes what is enought but why can not upload code that is mystery to me

all this code tried
https://drive.google.com/drive/folders/ ... sp=sharing

bat only FreeMemory.py can upload and run ..

The 411RE has 112kiB of space on the internal filesystem.

Has it ever been able to successfully copy the files? i.e. did it suddenly stop working? Have you tried copying the files with a different mechanism (e.g. rshell or pyboard.py).

i face this problem on both board Nucleo f411 or Nucleoo F401 (only short file with 3 lines can upload) ,during file upload (with more than 4 line) it give me download false4 always only and before upload i always restart board (to be able also to delete blank uploaded files on board)

seems communication breaks something

If I remember correctly, then Nucleo boards required explicit "flush" after writing each block while uploading, otherwise there was very long delay before next command could be issued and this may have confused uPyCraft.

I recommend to try freshly published Thonny 3.3.0 beta (https://github.com/thonny/thonny/releases/tag/v3.3.0b2). With it I could upload files to my Nucleo F401RE without problems.

(macOS binaries for Thonny 3.3.0b2 are coming soon)
