Re: [RSHELL on nucleo L476rg ] Unable to copy py files to flash
@Pythoncoder I tried the commands and this is what I got
Code: Select all
D:\nw\upython\stm32\nucleo_l46rg\code> repl
Entering REPL. Use Control-X to exit.

MicroPython v1.14 on 2021-02-02; NUCLEO-L476RG with STM32L476RG
Type "help()" for more information.

>>> import os
>>> os.listdir('/flash')
['boot.py']

Re: [RSHELL on nucleo L476rg ] Unable to copy py files to flash
Thanks for your prompt reply @pythoncoder. I tried the commands as per your suggestion. I got ['Flash'] after running the commands and then I again tried putting a .py file into flash and nothing happened. I waited for whole 5 minutes and the screen was stuck at the last line in the code mentioned b...

Creating zip file in ESP32 flash
Hello everybody,
Is there a way to create a zip file in esp32 flash using micropython. I need to create a zip file of multiple .csv files containing sensor data.

Getting Image file(jpg/jpeg) in esp32 file system.
Hello Everyone
I just want to know, is there any way by which we can get an image file in esp32's file system(SPIFFS) serially similar to what we have in Arduino through the ESP sketch data upload mechanism.
Thanks!

Disabling REPL on ESP32
I have an application where I store wifi credentials on a text file inside the flash. I have encrypted the password using the cryptolib library but still, REPL exposes the file system and keys would be accessible making the encryption useless. Even if I store my keys in a frozen module, it wouldn't ...

Double underscore before a name isn't working in micropython
It's a sample code I executed in micropython. class Student: def __init__(self,name): self.name=name self._name1=name self.__name2=name p=Student('abc') print(p.name) print(p._name1) print(p.__name2) and the output I received abc abc abc p.__name generally generates an error in the python interpreter.
