I think I have followed building instructions but the board fails to initialize. with most default config settings, except To build with psRAM support: In menuconfig select → Component config → ESP32-specific → Support for ex...

Nucleo F767 can't access REPL

Have tried accessing REPL through St-Link virtual com port that should be connected by default to Uart -3 PD8 and PD9. Virtu...

Re: STM32 Increasing Stack, Heap and/or Filesystem size

I am looking at evaluating Micropython on STM32F767ZI Nucleo development board. At this stage I am not set up with a tool chain to build my own firmware. Based on "standard" daily built firmware from Micropython downloads. 1. What is the maximum size of filesystem available in flash? 2. How much fre...

Thanks Robert,
flash_mode=dio


This did the trick, works fine now.

Thanks Robert,
Yes, clean erased and tried 0x1000 offset as you stated in earlier post but no go.
Have tried yesterday's and today's build with no success.

Re: Install is failing

Daily build ESP32 firmware is not installing on ESP-WROOM-32 using esptool. This is only happening with firmware built during last few days or so. Previous builds are OK esp32-20170807-v1.9.1-394-g79feb956.bin (latest) After install, rolling error message: Flash read error 1000, Falling back to comm...

Re: uPyCraft(micropython IDE) released

Tested briefly with ESP-Wrom32 Development board. Appears to be working OK.
Also tested briefly with ESP8266 NodeMCU.


As a windows GUI makes life very easy, can concentrate on more productive micropython development rather than command line operations.

Re: uPyCraft(micropython IDE) released

Nice, simple, effective.

Like the easy way to upgrade firmware.
Simple and easy windows mouse click to save, upload, execute applications, particularly easy switching between application code execution.

Looking forward to pyboard/stm microcontroller support.
Well done. ;)

Re: How can I use Webrepl for ESP32?

BUMP

Can anyone shed any light on WEBREPL or OTA file/code upload progress for ESP32?
