Can't upload to ESP32-S3-DevKitC-1-N32R8V using Thonny

[ZacharyInDallas]

I bought this board:

ESP32-S3-DevKitC-1-N32R8V

WiFi Development Tools - 802.11 Gen-Purpose Dev Bd, embeds ESP32-S3-WROOM-2-N32R8V, 32 MB Octal flash & 8 MB Octal PSRAM, w/ Pin Header

I am using Thonny to upload my MicroPython code and data.
I can get a REP, which gives:

MicroPython v1.19.1 on 2022-06-18; ESP32S3 module with ESP32S3

When I try to upload a data file, it fails with:

PROBLEM IN THONNY'S BACK-END: Exception while handling 'upload' (thonny.plugins.micropython.mp_back.ManagementError: Command output was not empty).
See Thonny's backend.log for more info.
You may need to press "Stop/Restart" or hard-reset your MicroPython device and try again.

Process ended with exit code 1.0

If I try to upload main.py it fails with:

main.py (47803 bytes)

Error: Could not copy main.py to /main.py: Could not open file /main.py for writing, output:
Traceback (most recent call last):

File "", line 4, in

OSError: [Errno 19] ENODEV

The first few lines of main.py are:

import configServer
import debug
import util
import machine

from micropython import const
import time

I tried the suggestions in the page below and it still does not work. I tried both the release version and the daily build.

This device wasn't supported by the Espressif IDF until quite recently - if you're not using a recent version of the IDF to build with, you'll find that the filesystem does not mount and you'll get errors much like you're describing.

I haven't gotten around to building this myself yet but I believe it should be possible with IDF v4.4.3.

[ZacharyInDallas]

I'm not building it myself. I'm using a pre-build binary. I've tried both octal spiram versions and plain ones like GENERIC_S3.

[mattytrentini]

Sorry, I should have been clearer. I believe that none of the pre-built binaries will work. My understanding is that the build system that produces the pre-built binaries is currently using stable versions of the IDF and we need to be using more recent versions to provide support for 32MB flash.

Until the build system is updated to use newer versions of the IDF I think you'll have to build your own (using the GENERIC_S3_OCTAL board definition as a base but using a larger flash definition).

I do have one of these boards and am keen to get it working but it's not quite at the top of my priority list. I'll try and get to it sooner rather than later!

[ZacharyInDallas]

I don't have to use the particular board that I bought. I chose it because it seemed to be one of the fastest with lots of RAM and flash. What ESP32 board can I buy that is fast, has lots of memory, and has a pre-built binary that will work?

[ZacharyInDallas]

Is there a way to be notified when a pre-built binary is available for this board that works?

[robert-hh]

It may be a problem of the interaction of your board with Thonny. Please try mpremote as the official tool to upload scripts, e.g.

mpremote cp <filename> :

: is the prefix for the board's file system. Use mpremote --help for a list of options. You can use mpremote ls to show the files on the board.

The name of the firmware I linked was wrong. In fact is was the S3 build with the v4.4.3 esp-idf firmware. https://github.com/robert-hh/Shared-Stuff/blob/master/firmware_ESP32_GENERIC_S3_SPIRAM_OCT.bin

We got this board to work in CircuitPython. Here's our board-specific sdkconfig: https://github.com/adafruit/circuitpython/blob/main/ports/espressif/boards/espressif_esp32s3_devkitc_1_n32r8/sdkconfig. It may be slightly helpful.

[robert-hh]

It looks like the config for the ESP32_GENERIC_S3_SPIRAM_OCT build has the flag for octal spiram set, at a flash size of 8MB.

I have the same board but N8R8. The ESP32_GENERIC_S3_SPIRAM_OCT nightly build works for me.
