Hi, how to know the value of the variables defined in link script file? for example, the following is the target.ld in ecos, could anybody know how to extract the __xxxx values from the generated ELF file? ============== start of target.ld===================== STARTUP(vectors.o) ENTRY(__exception_reset)
