Hi,
It seems I am overlooking something obvious as I get the impression people have long ago resolved this issue and I am not able to move a millimeter forward. I am trying to avoid the use the JTAG 4-pin interface as the Espressif literature seems to state that the USB native port, is the way to go for simple upload and debugging of the C3 and S3 family. I paid special attention to maxgerhardt posts to no avail. My goal is to be able to setup a configuration for any ESP32-S3-DevKitC-1.1-NxRy, to upload and debug over the native USB interface. I expect to use this Wroom processors in two coming projects.
In this case I am trying to have a successful setup for an ESP32-S3-DevKitC-1.1-N8R2-v1.1 using the native ESP32-S3 USB interface (D+ and D- for uploading and debugging) and despite having played with many platformio.ini options (not shown for keeping this post as short and as clean as possible, that I tried during 2 days of dozens of suggestions) I have never been able to get a different “Flash” and “RAM” total, like the one showed in the snippet further down (327.680 RAM and 3.342.336 Flash) which is odd as many PlatformIO community posts, report having succeeded to recognize their particular processor storage FLASH/PSRAM combination (I assume my case is qio_qio).
My board has an USB and UART microUSB port (S3-DevKitC-version 1.1) and on both I am able to upload the code but only on the USB port I am able to get the output of the Serial Monitor (printf instructions in code). I have installed the libsub (Win USB) driver in my machine and when the board is plugged on the PC-USB port I get COM26. Not sure how to enforce libsub usage?
As you can notice on platformio.ini, I tried to use a different board directive “board = esp32-s3-devkitc-1-n8r2v”, that I stored in the OpenOCD “boards” directory with the changes that might have an effect, but with no success as shown further down with the message “Error: esp_usb_jtag: could not find or open device!”
Thanks for any advice, the lines staring with a bunch of “*” have text at the end describing what comes next.

. Anyway going down that path I noticed that only Interface 0 had to be seen as a COM port, which made me decide to reattempt platformIO and everything worked.
