Specific sketch will not upload. The upload reports success but the old code persist

Official Hardware Nano Family Nano ESP32

Hi, I have a sketch that will not upload to the nano ESP32, although no compile and download errors are reported.

Other sketches (like blink example or a sketch similar to this specific sketch) do upload and run normally, but when I upload this specific sketch the blink (or previous) sketch remains, without any errors. See output below:

Sketch uses 1713097 bytes (54%) of program storage space. Maximum is 3145728 bytes.
Global variables use 57772 bytes (17%) of dynamic memory, leaving 269908 bytes for local variables. Maximum is 327680 bytes.

DFU state(2) = dfuIDLE, status(0) = No error condition is present
Done!

I hesitate to reveal this sketch on the internet (it is also quit big), so first I want to know what causes this problem and how can I determine what is wrong with my sketch?

I'm using arduino nano ESP32 with 2.0.18-arduino.5

Thanks for any help

It is going to be difficult to provide help unless you post the sketch that causes the problem. What devices are connected to the board and how is it powered ?

3

The upload completed normally. Check the Arduino documents for how to make the DFU sketch run. The docs should tell you how to make it run.

4

I searched on "no error condition." Maybe this helps.

status(0) = No error condition is present

Thanks for your responses. I think it is a problem with this specific sketch, because I can upload and run other sketches normally. Only with this specific sketch the upload reports succes, but the old code persist.

I used a similar sketch (with the same libraries) and had no problem with uploading and running it. Recent uploads of this similar sketch also runs without issue's.

I use Adafruit_GFX, Adafruit_BNO055 , esp_wifi.h, esp_now, Wifi.h libraries. Example sketches with these libraries runs without issue's.

What happens after the upload of a sketch and when is the new sketch "not accepted"?
Meanwhile, I'll do some more testing with the code.

6

Put a serial.print() message in setup() right after you set the Baud rate and see if that message is displayed.

7

Thanks for your suggestion. Point is that the old code (from the previous upload) persist. So it runs the code from the previous upload.

8

You have failed to tell us the difference between the old code and the new code. Adding the message will definitely produce a new code that is not the old code.

9

Is it possible that the PROGRAM has changed, but the DATA has remained (in FLASH)? Can FLASH be erased? Can all memory be erased?

Due to being unqualified to read the sketch, I could not dig through it.
