Hello to all,
I had a pointer out of range linkage error with altera 7.2. The gcc version is 3.235. It seemed I had to use "far" pointers compilation. So I have solved the issue using the compilation option G2. Now I have faced another problem. When I compile the software using G2 and some optimization level. For instance O1, O2 or other, the application links successful, but crashes at runtime. It works fine with no optimizations ( O0 ), but I need to launch it with optimization level O2. So here are my options for Debug and Release: For Debug: CC_DBG_FLAGS = -G2 -MD -DSYSTEM_BUS_WIDTH=32 -DALT_NO_INSTRUCTION_EMULATION -D_TARGET_DEBUG -c -D__hal__ -pipe $(LIB_SYMBOLS) -mno-hw-mulx $(CC_HW_FLAGS) -g -O0 -Wall $(CC_GCC_DBG_FLAGS_USER) $(INCLUDE_FLAGS) For Release: CC_REL_FLAGS = -G2 -MD -DSYSTEM_BUS_WIDTH=32 -DALT_NO_INSTRUCTION_EMULATION -c -D__hal__ -pipe $(LIB_SYMBOLS) -mno-hw-mulx $(CC_HW_FLAGS) -O2 -Wall $(CC_GCC_REL_FLAGS_USER) $(INCLUDE_FLAGS) So the only difference between debug and release flags is in the option: -O0 for Debug and O2 for release. In Release my application crashes and this is because of the combination of G2 + O2. It also crashes with the combinations: G1 or G0 + O2. same with O1 or O3. Does anybody have faced such an issue and is there a way I can fix it ? Thanks in advance.Link Copied
