Trying that it gives me the output:

  fconfig test started
  ... done

Any suggestions?

Uhhh - not really. A few dumb questions though ...
Does issuing a Redboot command fconfig -l -n show the variables as 
expected ?
Do you have the virtual vector interface enabled 
(CYGINT_HAL_VIRTUAL_VECTOR_SUPPORT) ?

For the record, I can confirm that CYGACC_CALL_IF_FLASH_CFG_OP() is
working correctly on Adder II in eCosPro 2.0.51 for retrieval of the
RedBoot IP address.

Could you try the following code ? It should display all available 
variables. It works on my system which is eCosCentric's v2.0.50:
HTH

#include <stdio.h>

#include <pkgconf/hal.h>
#include <cyg/hal/hal_if.h>
#include <cyg/infra/diag.h>

void test_func(void)
{
    // Testfunktion 1: Ausgabe der fconfig-Variablen
    struct cyg_fconfig fc;
    char key[64];

    diag_printf("fconfig test started\n");
    fc.offset = 0;
    fc.key = key;
    fc.keylen = sizeof(key);
    while (CYGACC_CALL_IF_FLASH_CFG_OP2(CYGNUM_CALL_IF_FLASH_CFG_NEXT, 
&fc)) {
        diag_printf("  Offset: %d, key: '%s', type: %d\n", fc.offset, 
fc.key, fc.type);
        fc.keylen = sizeof(key);
    }
    // zurück
    diag_printf("... done\n");
    return;
}

This version number only means something to eCosCentric.  It corresponds
to a pretty old version of eCos (around 2 years old).

I tested using the most up-to-date eCos from CVS.  It looks like
if you want this to work, you'll need to update your repository.

[ECOS] re: Reading flash config value from application

[Andre-John Mas]

Hi,

Just tried the code below and the 'CYGACC_CALL_IF_FLASH_CFG_OP' call returns false, just as in the code I had.

Its possible as Thomas suggests that maybe I have code which does not match what Gary has. I am currrently using 2.0.51, I believe.


#include <stdio.h>
#include <cyg/kernel/kapi.h>
#include <cyg/hal/hal_if.h>
#include <network.h>

#define CONFIG_IP 5

int
main(int argc, char *argv[])
{
    unsigned long addr;

    if (CYGACC_CALL_IF_FLASH_CFG_OP(CYGNUM_CALL_IF_FLASH_CFG_GET, 
                                    "bootp_my_ip", 
                                    &addr, 
                                    CONFIG_IP)) {
        diag_dump_buf(&addr, sizeof(addr));
    } else {
        printf("Can't get 'bootp_my_ip'\n");
    }
    printf("fconfig_test done\n");
    return 0;
}
