执行过程如上，然后就死机了，看了网上的**，说是u-boot和linux中的参数不匹配，
但是我的U-BOOT中设置的波特率是38400，bootargs=console=ttyAM0,38400;
linux中的串口驱动：
static int __init ks8695_console_setup(struct console *co, char *options)
{
struct uart_port *port;
int baud = 38400;
int bits = 8;
int parity = 'n';
int flow = 'n';
/*
* Check whether an invalid uart number has been specified, and
* if so, search for the first available port that does have
* console support.
*/
port = uart_get_console(ks8695_uart_ports, UART_NR, co);
if (options)
uart_parse_options(options, &baud, &parity, &bits, &flow);
else
ks8695_console_get_options(port, &baud, &parity, &bits);
/* The spinlock is setup in uart_add_one_port function but that
function is not called yet.
*/
spin_lock_init(&port->lock);
return uart_set_options(port, co, baud, parity, bits, flow);
}
照目前看，两边的波特率是一样的。
问题：
1.死机的原因是由波特率的不同造成的吗？
2.我这样的分析对吗？
3.还有其它的原因及其解决方法吗？ |
