We are in the need to create a portable pocked programmer to flash units in the field. We currently have one now that reads a firmware.bin file from a uSD card. But that uses the TX,RX, EN & IO0. to the other ESP32 device. Works fine, however we are changing all out product to use the newer ESP-S3, ...

Have you programmed it yet? If not, flash some code to it. You should see a port appear. Also, another thing to try is use menuconfig and change "Channel for console output" to be USB Serial/JTAG Controler) It under Component config -> ESP System Settings. Rebuild, and flash it should work normally ...

What IDE are your using ?

I recently switched framework from Arduino to ESP IDF. I've been strugling to implement my w5500 SPI_ETH dev board for the simple fact that the featured example (https://github.com/espressif/esp-idf/bl ... ple_main.c) uses an interrupt pin that is not mapped on my board. Did you run menuconfig to c...

Though that change might be working for you. I see the EN signal toggling many times in a short period. It should not be doing that.
The typical fix is to put a 0.1uf cap from EN to GND, along with a 10k to 3.3v.

Have you looked into ESP-NOW?
With little code modification to OTA you could have your master push out the update to all units paired to it.

Did you run menuconfig on the blink example and configure the demo for your board ?

Ever since the S3 came out we have developed several products with it. It's my go to part for anything that needs a micro. Today we got a project that needs Ethernet, and I was shocked to see that they left out the RMII. Crap!!! Espressif, your products are economical, saving $0.001 to remove a feat...

ESP_Sprite, he is saying if you plug in a USB device into the kit, J4 does not supply power to that port.
If he's going to plug in a device into J4 he could jumper across D7.

I think IO16 is used for PSAM.
