Greetings,
I have configured the kernel to use 3 serial ports and enable the uarts in arch/arm/mach-davinci/board-dm646x-evm.c as below:
static struct davinci_uart_config uart_config __initdata = {
.enabled_uarts = (7 << 0),
};
Still I am unable to send data on UART1.
PINMUX0 and PINMUM1 and VDD3P3V_PWDN are OK. But the MDR1 register is 0x07 indicating that UART is disable. Even if I enable it, I still cannot transmit.
Am I missing any thing?
Has anybody enable UART1 with open source davinci linux 2.6.32?
Thanks,
Amit
