[SooDragon]

Board

ESP32 C3 dev board

Device Description

Hardware Configuration

ESP32-C3FH4
USB_N to GPIO18
USB_P to GPIO19
Schematic.pdf

Version

latest master (checkout manually)

IDE Name

Arduino IDE 2.3.2

Operating System

MAC OS Sonoma 14.4.1

Flash frequency

80MHz

PSRAM enabled

no

Upload speed

921600

Description

After Updated to 2.0.16, Error occurs and says
"
A fatal error occurred: No serial data received.
Failed uploading: uploading error: exit status 2
"

It happens when I activate USB CDC On Boot function.
if I turn it Off, it is fine
I also tried Upload Speed to 115200, but it also didn't work.
I tried remove Arduino IDE and Arduino15 folder and re-installed, but it didn't work either

These are the scenarios worked for me

1. Flash dummy firmware through VS Code, Espressif IDF extension
   it will allow Arduino IDE to flash code for once.
2. Or when I installed Version 2.0.14, It worked just fine.
   

Sketch

void setup() {
  Serial.begin(115200);
}

void loop() {
  ;
}

I have the same issue.

i still didn’t fine the solution

any help is welcome :)

[me-no-dev]

This is fixed in RC3, but for first flash you will need to manually enter download mode (hold Boot while resetting)

[spilz87]

@me-no-dev thanks for your reply

For people who use stable release 2.0.X
It will be fixed in next release too ?

[me-no-dev]

@spilz87 yes. Fix will be ported to 2.x and new 2.0.17 will probably be released

[spilz87]

Nice 👍

Do you know what file(s) we have to modify to solve it in 2.0.16 release ? (If it’s not too much)

[me-no-dev]

There will be a pull request with all changes. You can copy then the changes to your current install. I think only HWCDC.cpp will be modified, but some small edits might need to be done in other places too.

[SooDragon]

Thank you for reply!

[SooDragon]

thank you for reply😆 it’s now clear, I’ll wait for next update.
should I close this issue? or leave it for Todo - core project roadmap?

[me-no-dev]

let's wait for the backport to 2.x first, then can be closed

I dont have this issue when I go back on v2.0.15 do I trued to get HWCDC.cpp and put it on V2.0.16 but doesn’t solve it

[ColdFireHunter]

Good day,
the same problem also happens with the ESP32-S3.
With v2.0.14 it works with v2.0.16 not but with RC3 it does again.

[VojtechBartoska]

@ColdFireHunter as mentioned above, it is fixed in 3.0.0-RC3 but it awaits a backport to 2.X version.

[spilz87]

If there is a way to know how to quickly fix it on 2.0.x (not official way but still a way) it would help a lot. I have to unmount everything everytime I want to upload a new software 🤯

thanks in advance

[SuGlider]

The 2.0.x core version shall be fixed and merged in about 2 weeks.

@SooDragon - PR #9660 is merged into release/2.x branch. This PR solves this HW USB CDC issue.

[SuGlider]

Feel free to confirm it before we close this issue.

applying this merge solve the issue for me, thanks a lot
