hi,
i have changed the line in omap_osk.c to:
static struct omap_uart_config osk_uart_config __initdata = {
.enabled_uarts = ((1 << 0) | (1 << 1) | (1 << 2)),
};
And all the three UARTs are enabled now as i can see in the kernel boot-log:
serial8250.0: ttyS0 at MMIO 0xfffb0000 (irq = 46) is a ST16654
serial8250.0: ttyS1 at MMIO 0xfffb0800 (irq = 47) is a ST16654
serial8250.0: ttyS2 at MMIO 0xfffb9800 (irq = 15) is a ST16654
A node called ttyS0 is already there which is linked to uart0.
when i type:
ls -l /dev/ttyS0
crw-rw-rw- 1 root root 4, 64 Aug 8 2004
\0x1b[1;35m/dev/ttyS0\0x1b[0m
# ls -l /dev/ttyS1
-rw-r--r-- 1 root root 16 May 21 2008
\0x1b[0;0m/dev/ttyS1\0x1b[0m
i have a question on the above output. the major and minor number for
ttyS0 are 4, 64 but fot ttyS1 i dont find a major number. what does
this indicate?
thanx for all the help.
regards,
Shareef
