Hello
im using basic usb over console exaple on my custom board .
i believe this task wont require any pins to be configured as my custom board is routed properly to all 4 pins required for USB
But i dont see any new serial com port when i flash this example to my custom board
this is my overlay file
/ {
chosen {
zephyr,console = &cdc_acm_uart0;
};
};
&zephyr_udc0 {
cdc_acm_uart0: cdc_acm_uart0 {
compatible = "zephyr,cdc-acm-uart";
};
};
my prj config file is this
CONFIG_USB_DEVICE_STACK=y CONFIG_USB_DEVICE_PRODUCT="Zephyr USB console sample" CONFIG_USB_DEVICE_PID=0x0004 CONFIG_USB_DEVICE_INITIALIZE_AT_BOOT=n CONFIG_UART_LINE_CTRL=y CONFIG_USB_CDC_ACM=y
this is my dtsfile

i invoke the device using same get device command that this example has
still i cant see any serial port
please help
