During the linking, i have these 2 warnings :
portage_task_latency.sct(15): warning: L6329W: Pattern LPC23_EMAC.o(ZI) only matches removed unused sections. portage_task_latency.sct(15): warning: L6314W: No section matches pattern LPC23_EMAC.o(RW).
It seems to be link to LPC23_EMAC.c; i put in options of file (memory assignement): ZI : IRAM2, Other Data IRAM2 (As in example Http_demo for MCB2300 with rtx)
I'll try to guess. The code and variables in the file LPC23_EMAC.c have been optimized away since they are unused in your program. Perhaps, you added the file to your project recently and the rest of your program doesn't reference it yet.
