ESP32 chip problems

[przybylanikodem]

For a couple of days I had a problem where i couldn't upload any code. I managed to upload some smaller codes like oled text control manually entering bootloader (boot button hold and reset button press). But my board isn't working after uploading bigger programms, the code is succesfully uploaded but it's not working. Does anyone have a clue on how to solve this? I'd be more than happy to provide more information if needed.

You certainly would need to provide more info. What board and chip specifically, what OS are you running on the computer, what SDK are you using, how are you putting the chip into download mode, how is the uploaded code 'not working'?

Chip: ESP32-WROOM-32
Board was listed on aliexpress as esp wrover
I have windows 10
SDK: Microsoft visual studio (platformIO) and arduino IDE
I managed to upload the code by holding the boot button and pressing reset button on board
Why the uploaded code isn't working: It should create new network, create a webserver on IP displayed on OLED connected to the board. OLED screen was working when i tried uploading simplier code just to display one word.

Have you looked at the terminal output when you ran the 'broken' program? What does it say?

Well, i didn't, my original code wasn't using it. I will check right now.

Now i can't even upload, my computer keeps beeping because it connects and loses connection with the board. The board itself is visible in the device manager. So i am not able to check serial monitor.

You uploaded your code but it is not working. Are you sure there is no problem with your code itself? If you now try to upload a basic code like the LED blinking or so on, can you upload it without any problem?

[przybylanikodem]

I can't upload anything for now. And I am 100% sure code is good, it was working just fine like 3-4 days ago.

So how can I fix that?

my computer keeps beeping because it connects and loses connection with the board.

Does it also do that when you manually (boot+reset button) put the chip into flash mode?
