Cannot use rshell or ampy about maixpy-v1 HOT 8 CLOSED

The current release of MaixPy does not support most of these features, we are developing another version of MaixPy, this version of MaixPy will support the fat file system. In addition, zmodem can be used to transfer small size script files to the development board.

This is awesome!

It worked on my jupyter_micropython_kernel first time!

The code I tried it out on is here: https://github.com/goatchurchprime/jupyter_micropython_kernel/blob/master/Maixpy_demo.ipynb

from maixpy-v1.

zmodem file transfer does not work well. The recommended xshell starts, but does not finish. Teraterm works, but is awfully slow (like 50 chars/second).

I have a patched code (main.c, uart_core.c and mpconfigport.h) here, https://github.com/robert-hh/K210-Stuff, which supports at least some of the ampy commands, like ls and put. ampy get is not supported. It looks as if ampy tries to upload code which fails at MaixPy.

from maixpy-v1.

Ampy get fails, because file read on MaixPy returns '' at the end of the file, and the code ampy uploads expects b'' as the EOF signal. The implementation of file.read() fails here for MaixPy. When opened in mode "rb", like ampy does, file.read() should return a bytes object. Instead that, it returns a string.

For ampy and rshell I have made a PR that fixes it (https://github.com/sipeed/MaixPy/pull/33). For rshell these changes were required, which are a little bit "hacky":

• board.name shall return a board name. That can be done by assigning one in boot.py, like
  board.name="maixpy"
• os.stat("/") shall return a tuple with 0x4000 in the first element. Since nitrogen spiffs does not know directories, that would require a special treatment of that name, and I doubt that it is worth the effort.

we support ampy and GUI tool uPyloader now, but not support rshell yet, see doc

we will close this issue, and if have question you can reopen or create a new one, thanks
