From fc2b399ac03b91339a1cb1bfd4d1a9ca87fe95c6 Mon Sep 17 00:00:00 2001 From: Loic Poulain Date: Thu, 25 Nov 2021 18:16:15 +0100 Subject: usb: gadget: Add CDC ACM function Add support for CDC ACM using the new UDC and gadget API. This protocol can be used for serial over USB data transfer and is widely supported by various OS (GNU/Linux, MS-Windows, OSX...). The usual purpose of such link is to access device debug console and can be useful for products not exposing regular UART to the user. A default stdio device named 'usbacm' is created, and can be used to redirect console to USB link over CDC ACM: > setenv stdin usbacm; setenv stdout usbacm Signed-off-by: Loic Poulain --- include/stdio_dev.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/stdio_dev.h') diff --git a/include/stdio_dev.h b/include/stdio_dev.h index 8fb9a12dd8..270fa2729f 100644 --- a/include/stdio_dev.h +++ b/include/stdio_dev.h @@ -103,6 +103,7 @@ int drv_lcd_init(void); int drv_video_init(void); int drv_keyboard_init(void); int drv_usbtty_init(void); +int drv_usbacm_init(void); int drv_nc_init(void); int drv_jtag_console_init(void); int cbmemc_init(void); -- cgit v1.2.3
