I have an issue with my ESP32-P4 Function_EV_board version 1.2. When using pioarduino 53.03.11 with Arduino framework, I get no output over serial, not even boot sequence. When I try with ESP-IDF as framework, everything works as expected.
I noticed that the eval board version 1.2 is missing a USB-to-UART Bridge chip, which the version 1.4 has. Could this have anything to do with that?
Is there any workaround? Has anyone encountered the same issue?
EDIT: I managed to figure it out, I found this thread ESP32-S3-LCD-EV-Board and added a few lines to build flags, so my platformio.ini looks like this:
[env:esp32-p4-evboard]
platform = https://github.com/pioarduino/platform-espressif32/releases/download/53.03.11/platform-espressif32.zip
board = esp32-p4-evboard
framework = arduino
monitor_speed = 115200
build_flags =
-DARDUINO_USB_MODE=1
-DARDUINO_USB_CDC_ON_BOOT=1
Now everything works as expected, even with board version 1.2.
