Hello XIE,

it has to be a problem with the linker script: OpenGEN/ld/arm7/lpc2468/lpc_e2468.cmd

in the script there is no section called exidx, for me is not clear why you need that section. you can add it and then it shall work. If the section is really needed we shall update the file on freeosek, but is not clear for me now, i will try to check why you need it...

Which user do you have on sourceforge, I would like to contact you per mail or chat so we can found the solution easily.

regards,
Mariano.-

Hi, Mariano:

Thanks for the help.

I try to add the following base on information: http://embdev.net/topic/129609

.ARM.exidx :
{
__exidx_start = .;
*(.ARM.exidx* .gnu.linkonce.armexidx.*)
__exidx_end = .;
} >flash

into the lpc_e2468.cmd file, but still failed to link

which arm-gcc are you using? I use the Sourcery G++.
