Hi,
My home made bootloader passes the following command
line "console=ttyS0,96008n" via ATAG_CMDLINE without
any issue. Also the bootloader takes care to configure
the uart1.
I had to add the printascii() in order to have some
debug messages.
I loosing something during the console_init()
execution flow.
console_int() @ printk.
|-> serial8250_console_init(); @ 8250.c
|-> serial8250_isa_init_ports(); @ 8250.c
|-> All the serial8250_ports[].port elements = 0
|-> register_console(&serial8250_console); @ printk.c
|-> serial8250_console_setup(console,
console_cmdline[i].options)
|-> port = &serial8250_ports[co->index].port;
if (!port->iobase && !port->membase)
return -ENODEV;
So since All the serial8250_ports[].port elements = 0
the configuration seated "console=ttyS0,9600n8" will
not be used to reconfigure the console.
If this is not the path used to reconfigure the
console via command line. Which one is the right one??
I probably missing something, or following the wrong
path.
Thanks in advance for any comments.
