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
