Thanks. Now it makes sense.
The FAQ link was difficult to see on my browser.

So a possible solution is to insert some delay (more than 10ms) after os.sync()?

Hi, Using MPy 1.17, stm32F405 I have a program that will do some os tasks on the flash memory such as renaming and moving files and directories. After this, it issues: os.sync() pyb.hard_reset() In some rare cases, it won't reboot as the file system became corrupted. So is it possible that os.sync()...

To create an integer array with a fixed length.
x=array.array('i',[0]*10)
This seems to create an array of 10 ints with zero initialization.
Very handy!

I found a solution. Basically it involves disabling USB (CDC and MSF) under certain conditions. Secure BLE is used to lock/unlock the REPL.

Hi, I would like to utilize a method to run python code that is signed or to look for a key file on the filesystem. I'm not looking for the ultimate security, but something better than what exists. I am not looking at encrypting code at the moment. Just a mechanism that resets the MCU if a signature...

so 'opt=3' prevents emitting any code for "assert" statements. So if I am using assert, I should set it to another value?
Where can i find a list of the options?

Well. This is embarrassing.
Thanks for pointing this out. Sometimes you can't see the forest from the trees...

Hi, I am trying to freeze some code. Board is a modified pyboard using a STM32F405 It works fine if I do not include __init.py__ in the manifest. Here is my manifest file: include("$(MPY_DIR)/extmod/uasyncio/manifest.py") freeze("$(MPY_DIR)/drivers/dht", "dht.py") freeze("$(MPY_DIR)/drivers/display"...

I am able to read and write to this region of SRAM with MicroPython with a STM32F405 (same as PyBoard) using upower.py.
Is it safe from normal MicroPython programs? In other words, is there a chance the bytecode or data can overwrite this region?
