[ECOS] Halting RedBoot

No, i'm sorry.
I found that _rb_gets() in cyg_start() returns immediately of no keys are pressed.
It has no return if i press keys until Return key.
Can turn it into a non blocked call if i press anyother keys than ^C (and timeout) ??

Yes, that does look like it will work.

[ECOS] Halting RedBoot

[S. Z.]

Hi,

I had the same problem. I solved it by using the following code in packages/redboot/src/main.c :

        while (script_timeout_ms >= CYGNUM_REDBOOT_CLI_IDLE_TIMEOUT) {
        #if 1
            if(_rb_break(CYGNUM_REDBOOT_CLI_IDLE_TIMEOUT)){
                res = _GETS_CTRLC;
                break;
            } else {
                res = _GETS_TIMEOUT;
            }
        #else
            res = _rb_gets(line, sizeof(line), CYGNUM_REDBOOT_CLI_IDLE_TIMEOUT);
            if (res >= _GETS_OK) {
                diag_printf("== Executing boot script in %d.%03d seconds - enter ^C to abort\n", 
                            script_timeout_ms/1000, script_timeout_ms%1000);
                continue;  // Ignore anything but ^C
            }
            if (res != _GETS_TIMEOUT) break;
        #endif
            script_timeout_ms -= CYGNUM_REDBOOT_CLI_IDLE_TIMEOUT;
        }

No, this is not how to fix the problem.

The problem is that this loop is calling _rb_gets() which is
expecting to read an entire line from the console.  If that
function sees any characters, it will wait until a complete
line is entered, regardless of the timeout.

The correct way to fix this would be to use mon_read_char_with_timeout()
instead of _rb_gets().  This will take a little while to update and
test, but if you're patient I'll give you a patch to try.

[ECOS] Halting RedBoot

[Stefano Mora]

Hi there,
I'm in a trouble with RedBoot cause during the boot it receives a character from the serial port (different from ^C) and the boot stops waiting for a Return.
I don't need this behaviour cause the serial port is shared with a printer that, when the board powers up, sends a char then the board stops.

My question is:
How can i jump it?
The code that enable the behaviour is
        } else {
                script = hold_script;
        }
??

If i comment out this code the bootloader can stops only with Ctrl-C ??

Thanks!
