I edited this file, i even verified in the debugger that the compiled stub
passed the correct BAUD_LOW in hal_diag_init

But still when booting off this stub I can't connect to 115200 but I can to
38400 

It's weird...

Does the stub use this function ?? 

...
[A check later]

Well in fact i just found code in plf_stub.c that says:

// 38400, COM1
#define CYG_DEVICE_SERIAL_RS232_BAUD_MSB    0
#define CYG_DEVICE_SERIAL_RS232_BAUD_LSB    3

And there is a function:
void hal_pc_init_serial(void) 

I don't understand well what are the purpose of this function when there is
already hal_diag_init() ..??

Thanks

Not for the PC target. Instead you need to edit
hal/i386/pc/VERSION/src/hal_diag.c. Look for BAUD_LOW.

[ECOS] Serial Speed with i386 PC target

[Fabrice Gautier]

Hi,

In the ARM PID board target it is possible to choose the serial port speed.
I'm loking for the same thing for th i386 PC Target.
And can't find it. If as with the PID board, should be somewhere in "eCos
HAL"-"i386 architecture"-"i386 PC target"
I can choose the serial line (or screen) to be used as diag output, but
can't choose the serial peed. 

It seems this is 38400 by default.

Thanks

A+
