Having trouble disabling USB to reclaim pins 19 and 20

[IcedRooibos]

In the past I had disabled USB on a custom build of micropython by changing sdkconfig.usb (#11315)

This time around when I change sdkconfig.usb to either of the following, the build still fails. Any advice on how I might fix this? Thank you!

CONFIG_USB_OTG_SUPPORTED=n
CONFIG_TINYUSB_CDC_ENABLED=n

CONFIG_USB_OTG_SUPPORTED=n
CONFIG_TINYUSB_CDC_ENABLED=n
CONFIG_TINYUSB_CDC_RX_BUFSIZE=256
CONFIG_TINYUSB_CDC_TX_BUFSIZE=256

I've worked out that CONFIG_USB_OTG_SUPPORTED is being set to y despite me setting it to n - checked through cmake build logs.

mpconfigboard.cmake

set(IDF_TARGET esp32s3)

set(SDKCONFIG_DEFAULTS
    boards/Q/sdkconfig.base
    ${SDKCONFIG_IDF_VERSION_SPECIFIC}
    boards/sdkconfig.ble
    boards/sdkconfig.spiram_sx
    boards/Q/sdkconfig.board
    boards/Q/sdkconfig.usb
)

sdkconfig.usb

CONFIG_TINYUSB_CDC_ENABLED=n
CONFIG_ESP_CONSOLE_USB_CDC=n
CONFIG_ESP_CONSOLE_USB_SERIAL_JTAG=n
CONFIG_USB_OTG_SUPPORTED=n

For now I manually removed all CONFIG_USB_OTG_SUPPORTED bits of code but that doesnt seem ideal - does anyone happen to know why this might be happening?

Does it help to remove the line

  espressif/esp_tinyusb: "~1.0.0"

from the main_esp32s3/idf_component.yml file?

[IcedRooibos]

Gave this a shot and it fails when trying to import usb.c

So I removed the usb.c and usb_serial_jtag imports from esp32_common.cmake

At which point it unfortunately fails the same way as it did earlier. Thank you for giving it a shot though!

Sorry for the slow reply on this one. There is an open issue that tracks this problem at #14217, there's currently no "good" way to do this. (Although there is a workaround described at #15769)
