Is it compulsory to add the node "virtualcom" to configure a USB virtual com port via USB-OTG-HS for STM32F407 under Zephyr 2.0.99?
I got the following code in DTS from a partner but it cannot be built properly. Error indicates that virtualcom does not have necessary properties. (It is said that the code was compiled in version 1.13.0.)
.......
usb_cdc: virtualcom {
label = "CDC_ACM";
};
chosen {
zephyr,console = &usb_cdc;
zephyr,sram = &sram0;
zephyr,flash = &flash0;
zephyr,ccm = &ccm0;
};
.......
......
&usbotg_hs {
status = "ok";
};
Moreover, the sample code (usb/console) only requires to add configure entries to defconfig so that I got confused. Thanks for your reply in advance!
