[ariga masahiro]

Hi,Sergei and others,

I found plf_misc.c,
but content is very diffrent with your answer.
I  put all content down.

Would you elaborate how to include your tweak
int my file?

Next is content of
C:\cygwin\opt\ecos\ecos-2.0\packages\hal\sh\inserter\current\src\plf_misc.c
------
#include <pkgconf/hal.h>

#include <cyg/hal/hal_if.h>             // interfacing API
#include <cyg/hal/plf_io.h>

externC void cyg_hal_init_superIO(void);

void
hal_platform_init(void)
{
#ifdef CYGPRI_HAL_SH_SH77X9_SUPERIO
    // Init superIO before calling if_init (which will use UARTs)
    cyg_hal_init_superIO();
#endif

    hal_if_init();
}

// eof plf_misc.c
--------

I am very obliged to you.

Masahiro Ariga

That was just a canvas. So, place the include lines on top of the
source, as you do it as well

#include <pkgconf/system.h>
#ifdef CYGPKG_REDBOOT
#include <redboot.h>            // script declaration
#endif

and the function in any other place

#ifdef CYGPKG_REDBOOT
# ifdef CYGSEM_REDBOOT_PLF_STARTUP
void
cyg_plf_redboot_startup (void) {
    ...
}
# endif // CYGSEM_REDBOOT_PLF_STARTUP
#endif // CYGPKG_REDBOOT

You use a very obsolete a eCos stuff. I would suggest you to update the
eCos stuff from the official eCos anon CVS:

http://ecos.sourceware.org/anoncvs.html.

I don't sure that RedBoot from ecos 2.0 did contain the needed things
for my tweak.

Re: [ECOS] Is there any way to branch in Boot Script

[ariga masahiro]

Hi,Sergei and others,

Thank you,Sergei,for your very "brainwashing" answer.

But although I earnestly grepped "cyg_plf_redboot_startup",
or even "CYGSEM_REDBOOT_PLF_STARTUP",
I could not hit any file in my ecos source directory.

Since your answer is very suitable to "what I want to do",
please elaborate a little more,please?

By the way my target uses SH7709 CPU.

I am looking forward to your kindly answer.

Masahiro Ariga

A bit more, redboot.cdl contains yet another option... So, with a code
above, you can run an alternate script instead default one, if you put
there something like this

cdl_option CYGDAT_REDBOOT_DEFAULT_BOOT_SCRIPT {1 {alt_script}};

Note: a declaration/filling that `alt_script' is your deal, certainly.

It's pity, but RedBoot != shell, so it hasn't such behaviours. Some guys
dream about those behaviours :-) But, every RedBoot command (redboot.h)
is just it

typedef void cmd_fun(int argc, char *argv[]);

Therefore, it is no way to return any result (Ups, I did think about
`argv' :). Also, there is no global variable, something like the DOS
`errorlevel' (to check/collect the fails) there. More that, if the
RedBoot's parser does meet wrong line in a script, it passes the line a
bit noisely and then it continues to parse a rest of the script.
 
>  3.Is there any way to realize above-mentioned "what I want to do".

I had same needs (to read the DIP switches). And I did use such a way.
Well, if your RedBoot/eCos aren't fucked binaries, i.e. if you have the
target sources, you can put same stuff in your plf_misc.c file

---------------------------------------------------------->8
#include <pkgconf/system.h>

#ifdef CYGPKG_REDBOOT
#include <redboot.h>            // script declaration

#define DIPSW_MASK (1 << 7)     // FIXME: put yours

#ifdef CYGSEM_REDBOOT_PLF_STARTUP
void
cyg_plf_redboot_startup (void)
{
    int             switches = 0;

    // put a code to read the switches here

    if (switches & DIPSW_MASK)
        // don't run the script
        script = 0;
}
#endif // CYGSEM_REDBOOT_PLF_STARTUP
#endif // CYGPKG_REDBOOT
---------------------------------------------------------->8

Note: before to build RedBoot with this tweak, set this option in your
`ecos.ecc':

cdl_option CYGSEM_REDBOOT_PLF_STARTUP {user_value 1};

For more details, look at cyg_start () in redboot/current/src/main.c,
you would find your own way for that.

[ECOS] Is there any way to branch in Boot Script

[ariga masahiro]

Hi,Everyone,

 I beseech you to help me out of next predicament.

 What I want to do is this:
  In RedBoot Boot Script,read Target Board DIPSW-settled value,
  and compare already-written value in a certain address.
　(for example,use mcmp command)
  If same, continue next Boot Script command.
  If differs,quit Boot Script and return to RedBoot's prompt.

 My questions are:
  1.Is there any way to know mcmp result(that is ,succeeded or errored).
    Preferably in RedBoot Boot Script.
　2.Is there any way to use branching statement(like,if-else),
    in RedBoot Boot Script
  3.Is there any way to realize above-mentioned "what I want to do".

 Please enlighten me,I am willing to accept any hints.

 Masahiro Ariga
