I did so from lowest and when I come to 115200 baud something strange happened
I got this output. And still this even if I changed to 115200 in my program

You are seeing the boot log in formation from the board which is at 115200. Since you know that printing to the monitor at that speed works correctly, I suggest that you change the baud rate in the sketch to 115200.
There may be some information available from the download if you go to file> preferences in the ide and select show verbose output on upload.
Please post the messages you receive.
Maybe try for now with Tools -> PSRAM: Disabled
I had already set 115200 baud in my program. After verbose output I got this message output which I think is the same as before changing verbose output

Ok, that is odd. Well there is only one more PSRAM setting left:
Tools -> PSRAM: QSPI PSRAM
The messages in #24 do look OK though.
I tried that too and it didn’t build
Are you still trying to load the simple serial printing test of Post #15?
sdkconfig.h is a file which should have been created when the esp32 core loaded into the ide.
On my computer it is at
"C:\Users\Owner\AppData\Local\Arduino15\packages\esp32\tools\esp32s3-libs\3.3.7\sdkconfig"
This error would speak to an issue with the core installation. Since this thread started with a problem of long download times perhaps the installation is not correct.
Yes the same program you posted only for now I have sett baudrate to 115200.
I do have a file called sdkconfig in the corresponding folder as you. But it is listed as FILE type not a .h file. But i could be opened in notepad
Yes. That's what I have.
I am running out of ideas and I'm starting to think you have an Alidud.
Have you tried to reload the board package?
There are many options available with the esp32S3 as the mcu. Why did you chose one in the Uno format?
Given that you have to chose the generic dev module for that board, there may be an issue with the pins file for the i/o.
Look in the variants file for all the boards with specific pin maps and ide support.
C:\Users\Owner\AppData\Local\Arduino15\packages\esp32\hardware\esp32\3.3.7\variants
Alidud ? What do you mean ?
I tried Reload Board data under tools. It didn’t change anything.
Do you ask why I purchased this particular board ?
In that variants folder I have 371 entries
That doesn't reload the board package to the ide.
Tools>Board>Board Manager>esp32 by espressive systems V3.3.7
Alidud ? What do you mean ?
Board from a low cost, low quality Chinese manufacturer which is DOA.
Dud purchased from AliExpress.
Hopefully not and lets see what a reinstall brings.
Are you on a laptop? If so, I would take it to a coffee shop where you can download in less time.
EDIT:
Do you ask why I purchased this particular board ?
Yes, It's unusual, and not listed as one of the 371 variants.
Do you mean remove and then install again ?
It is purchased from AliExpress. I ordered it since I saw it at a low price. My impression is not bad quality but rather lack of documentation.
But since a build and upload pass without any error is that not a clear sign that I have selected the correct board ? Also the ESP unit put out text messages (it continue with this without interruption). If it has command over the serial port how can a sketch print anything ?
I modified the program with a blink function which does not work. But when I got the board a blink proigram was already installed and blinking the led. After uploading my sketch no more blinking. So the original sketch was clearly overwritten. But not being run
In the variant folder I find a entry called esp32_s3r8n16. That seem to be my board
I am not on a laptop but a desktop computer running Win 10
Yes.
In the variant folder I find a entry called esp32_s3r8n16. That seem to be my board
Thr r8and n16 relate to memory and not the pin outs. You can look in the variants file for that board and see if the pin outs match up with yours.
Removing and then install didn’t change anything
But changing the board to ESP32-S3-USB-OTG did make the print in the sketch work
But Blink does still not work
Very strange. What are your Tools selections for upload mode and usb mode? In you select that board, can you print at different baud rates, or just 115200?
But Blink does still not work
It's not clear what i/o pin is connected to the built in led. Based on board position, I think that i/o 12 is in the position of pin 13 on a uno which is the built in led for blink.
These guys sell the board and maybe make it as well. They have some online customer service, and you may be able to ask questions about the built in led and the serial printing anomalies.
Uploadmode = UART 0 hardware CDC
USB mode = USB OTG
I have tried many pin numbers for led pin (including 12) and no one work. According to AI it should be 48 but that does not work
Your board is very confusing to me and I leave you to sort things out with TZT when they open for business.
Good luck finding the LED. It looks like it might be multi colored and could be either common anode or cathode.
I solved it with AI. The LEd was indeed a RGB multicolored one and coud not be turned on by setting a pin to high. I needed a Adafruit library
