Arduino nano 33 iot - program don't start #113

Closed AndyF1995 closed 4 years ago

AndyF1995 commented 4 years ago

Operating system: Win10 x64

PlatformIO Version : 4.3.4 on VScode

Description of problem

When I upload a simple "blink" on Arduino nano 33 iot, after the last reset the program don't start its execution on microcontroller. Same program works on different architectures like AVR and STM32. For a new upload I need to put my nano on bootloader mode by pressing reset button twice.

I tried to:

I find a workaround:

  1. Create a new project
  2. Copy all sources files in it
  3. Build and upload
  4. BUT... When I connect a new board, sometimes I have same issue

Steps to Reproduce

The error is not systematic, but it seems to be happening with this procedure:

  1. Plug a new Arduino nano 33 iot on USB
  2. Load "blink"
  3. Change board with different architecture
  4. Load "blink"
  5. Plug a second new Arduino nano 33 iot on USB
  6. Load "blink"

[platformio]
default_envs = nano_33_iot

Sorry, today I hardly debug it. Probably, there is an error in my custom linker script.
