For testing, it may be easier to load U-Boot into RAM that flash it every time. If so, since there's only 1 USB port, you'll need to use "usb reset" to re-scan that USB port. That will only work with the following patch, which I'll send in a minute: diff --git a/include/configs/tegra-common-post.h b/include/configs/tegra-common-post.h index c3ad8beb903d..9ab58555378c 100644 --- a/include/configs/tegra-common-post.h +++ b/include/configs/tegra-common-post.h @@ -26,10 +26,11 @@ #define STDIN_KBD_KBC "" #endif -#ifdef CONFIG_USB_KEYBOARD +#if defined(CONFIG_USB_KEYBOARD) && !defined(CONFIG_SPL_BUILD) #define STDIN_KBD_USB ",usbkbd" #define CONFIG_SYS_USB_EVENT_POLL #define CONFIG_PREBOOT "usb start" +#define CONFIG_SYS_STDIO_DEREGISTER #else #define STDIN_KBD_USB "" #endif
