I am making a project about DS80C400. I need to relocate the program objects of some library files,but only some of them can be relocated(for example rom_task.lib),others can not,such as ROM_SOCK.LIB. The result is: *** ERROR L121: IMPROPER FIXUP MODULE: .\rom_sock.lib (ROM400_LIB_SOCK_SYNCH) SEGMENT: ?PR?_SYN_SEND?ROM400_LIB_SOCK_SYNCH OFFSET: 000000H Program Size: data=83.1 xdata=12165 const=4003 code=14931 Target not created I want to know the reason.I will appreciate your timely help very much.
