Yes, I think the intention of the error above is that ecosadmin "detects"
error in pkgadd.db and exists making tar also exists. Anyway, the file is
OK, I've decomplressed it and did
cat pkgadd.db >> <path>/ecos.db
I've also copied Jerzy's if_npe.c and now I'm fighting with various
compilation issues. Generaly Intel code's complaining about RebBoot not
enabled. Is RedBoot required for this to work? i.e. do I need to build my
NPE-enabled eCos app including RedBoot just to be able to build it?
Now, you do not want RedBoot.
I also though that, but unfortunatelly whole code looks like expecting
RedBoot... Now I'm fighting with this (RedBoot still not enabled in
config), which seems to be MAC address "detection":
if_npe.c file from Jerzy:
806 // Set MAC address
807 #if defined(CYGSEM_NPE_REDBOOT_HOLDS_ESA)
808 {
809 char *cfgname = NULL;
810 #if defined(CYGSEM_INTEL_NPE_USE_ETH0)
811 if (p_npe == &npe_eth0_priv_data)
812 cfgname = "npe_eth0_esa";
813 #endif
814 #if defined(CYGSEM_INTEL_NPE_USE_ETH1)
815 if (p_npe == &npe_eth1_priv_data)
816 cfgname = "npe_eth1_esa";
817 #endif
818
819 #elif defined(CYGHAL_GET_NPE_ESA)
820
821 mac_ok = CYGACC_CALL_IF_FLASH_CFG_OP(CYGNUM_CALL_IF_FLASH_CFG_GET, cfgname,
822 p_npe->mac_address, CONFIG_ESA);
823 }
1. cfgname is used here, but it is not defined. It is defined in above
#ifdef statement.
2. CONFIG_ESA is not defined. It seems CONFIG_ESA is defined to 6 when
RedBoot is enabled
824 #else
825 #error No mechanism to get MAC address
826 #endif
827
828 if (!mac_ok) {
829 #ifdef DEBUG
830 diag_printf("Error getting MAC address.\n");
831 #endif
832 return 0;
833 }
here we test !mac_ok, but strangely when CYGSEM_NPE_REDBOOT_HOLDS_ESA is
defined, then mac_ok is not set to true.
So now, I'm searching where is all these defines provided to find out more
info about this issue.
Thanks,
Karel
