When a real UART (CONFIG_UARTx_SERIAL_CONSOLE) is selected as the system console while CONFIG_ESP32S3_USBSERIAL is also enabled (e.g. to keep /dev/ttyACM0 available as a secondary device alongside an external console UART), the unconditional #ifdef CONFIG_ESP32S3_USBSERIAL # define CONSOLE_DEV g_uart_usbserial #endif block silently redefines CONSOLE_DEV, clobbering the correct earlier definition that pointed it at the chosen UART device. Confirmed on real hardware (Seeed XIAO ESP32-S3): with UART0 selected as console and USBSERIAL also enabled, the board boot-looped on RTCWDT_RTC_RST every ~8s, never reaching NSH. With this fix, NSH comes up normally over UART0 and /dev/ttyACM0 remains available. Signed-off-by: Felipe Moura <moura.fmo@gmail.com> Assisted-by: Claude:claude-sonnet-5 |
