I can't upload large program code

[Zsolt56]

Board

Arduino Nano ESP32

Device Description

PLATFORM: Espressif 32 (6.5.0+sha.9b0c95d) > Arduino Nano ESP32

Hardware Configuration

HARDWARE: ESP32S3 240MHz, 320KB RAM, 16MB Flash

Version

v2.0.14

IDE Name

PlatformIO

Operating System

Windows 10

Flash frequency

240 MHz

PSRAM enabled

yes

Upload speed

115200

Description

I run into an upload problem: step by step developing my program, I reached a size limit where i cant upload the full code any more.
While there are a plenty of room for code:
RAM: [== ] 18.5% (used 60560 bytes from 327680 bytes)
Flash: [====== ] 55.3% (used 1088161 bytes from 1966080 bytes)
the upload process stops at 95%:
Download [======================= ] 92% 1007616 bytes
Download [======================= ] 95% 1040384 bytes failed!
DFU state(10) = dfuERROR, status(3) = Device is unable to write memory
**** [upload] Error 74*

I think here should be a barrier, because if I shring the code (omitting a part of it), the upload works fine and the code runs without any problem. I tried looking for issues around the partitions.csv, but I haven't found any solution yet

Debug Message

DFU state(10) = dfuERROR, status(3) = Device is unable to write memory
  **** [upload] Error 74*

Other Steps to Reproduce

I also tried to upload similar size code on Arduino IDE 2.3.2, with the similar results

I have checked existing issues, online documentation and the Troubleshooting Guide

Could you please post the partitions.csv used in the project?

[lbernstone]

The whole platformio.ini would be useful.
To change partition table:
https://docs.platformio.org/en/latest/platforms/espressif32.html#partition-tables
To change maximum upload size:
https://docs.platformio.org/en/latest/projectconf/sections/env/options/platform/index.html#more-options

Here is the platformio.ini file:

; Library options: dependencies, extra library storages

;upload_protocol = esptool ;for data uploading
upload_protocol = dfu ;for program uploading

Earlier I have tried with 2 different partition files, without any effect. Later however I have installed the ESP-IDF and download the hello_world project with it, as a test. It worked smootly. Then I returned to my project on Platformio, built a filesystem image, uploaded it, then recomplied the program and I could upload it without any size problem (it was strange, that the program uploading was working only with esptool, not with dfu, as it was earlier). So, the ESP-IDF reapired something and now I can upload code without size problems, except the fact, that only the 1st upload worked through the USB, after it I receive the usual error 74 code. But fortunately the program includes an OTA option, so now I can upload on the OTA channel. I have no idea, what ESP-IDF could do and the PlatformIO could not. As the Arduino Nano ESP32 is really a problematic board, it is possible, that somewhen and somehow I made a wrong step during the program development...

Do not define any partition scheme yourself for this board. You will encounter issues.
The partition scheme is defined in the boards manifest https://github.com/platformio/platform-espressif32/blob/develop/boards/arduino_nano_esp32.json

This should work:

; PlatformIO Project Configuration File
;
; Build options: build flags, source filter
; Upload options: custom upload port, speed and extra flags
; Library options: dependencies, extra library storages
; Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

[env:arduino_nano_esp32]

The boards design concept is very different compared to other boards. The upload of firmware is ONLY done with the dfuutil which is installed automatically from Platformio (when this board is used). So problems with uploads have nothing to do with Platformio or ArduinoIDE. Issues with the uploader dfuutil and the board should be directly addressed to the Arduino team (the board seller).

[SuGlider]

By the way, Arduino.CC (board maker) has its own board definition for the Arduino Nano ESP32, when using the Arduino IDE (I know it's about PlatformIO, but just in case).

@Zsolt56 - any further question? Otherwise we can close the issue.

Hi Rodrigo, Yes, you can close the issue. Kind Regards, Zsolt
