Hello Jonathan and Andew,

Thanks for providing the step to get the mapfile. I have provided below the part of mapfile generated.


ecos.table.RedBoot_inits.data.0000do_flash_init
0x00040964 0x4 redboot-Aug8/Firmware0522/bootmonitor/src/build/install/lib/extras.o
0x00040964 _init_tab_0000do_flash_init
.ecos.table.RedBoot_inits.data.0000load_flash_config
0x00040968 0x4 redboot-Aug8/Firmware0522/bootmonitor/src/build/install/lib/extras.o
0x00040968 _init_tab_0000load_flash_config
.ecos.table.RedBoot_inits.data.9999net_init
0x0004096c 0x4 redboot-Aug8



At address 0x00040964 there is a do_flash function. I have included a printf statement at the beginning of "do_flash"
function. But I am not seeing that printf getting executed.


Could please let me know what could be missing or wrong?

regards
G.Muruganandam

I did print out init_entry->fun, it shows 0xffffffff
It looks like the entries have not been populated with the correct function pointers.
Could you please let me know how this can be resolved?


Generate a linker map and find out where that entry should have come from. Relink redboot and add -Wl,-Map,mapfile to the link line.

Would it be possible for you to list the steps to do the above step?

In your CDL configuration edit CYGBLD_GLOBAL_LDFLAGS and append -Wl,-Map,mapfile then save and rebuild. Or uncomment and change the user_value for CYGBLD_GLOBAL_LDFLAGS in ecos.ecc in the command line tools if that's what you are using.


When you rebuild redboot, you'll probably find "mapfile" in redboot/current/mapfile in your build tree (or v2_0 instead of current if using eCos 2.0).

Last I knew the intel tools worked (although they may have been updated since I last used them).

I am currently using the Intel's Xscale toolcahin xscale-010827

There are other versions, up to 021022 http://www.intel.com/design/intelxscale/dev_tools/021022/index.htm
