#ifdef CONFIG_BOARD_EARLY_INIT_F

int board_early_init_f (void)

int uart_ids = 0; // bit mask of which UART ids to enable

#ifdef CONFIG_TEGRA2_ENABLE_UARTA

uart_ids |= UARTA;

#endif

#ifdef CONFIG_TEGRA2_ENABLE_UARTB

uart_ids |= UARTB;

#endif

#ifdef CONFIG_TEGRA2_ENABLE_UARTC

...........

Add some entries to 'include/configs/harmony.h. For example:

#define CONFIG_TEGRA2_ENABLE_UARTA

#define CONFIG_TEGRA2_ENABLE_UARTB

#define CONFIG_TEGRA2_ENABLE_UARTC

#define CONFIG_SYS_NS16550_COM1 NV_PA_APB_UARTC_BASE

#define CONFIG_SYS_NS16550_COM2 NV_PA_APB_UARTA_BASE

#define CONFIG_SYS_NS16550_COM3 NV_PA_APB_UARTB_BASE

8.4 Linux

Environment on Windows

If you want to implement a Linux

environment on a Windows

operating system the ORACLE

VirtualBox

is a good solution. For further information see

https://www.virtualbox.org/

VirtualBox

supports all USB interfaces from the host and configures the guest operating system with a

virtual USB controller. Likely there are some exceptions, for example the access to the

Client Port Driver
