Previous version can be found from [1]. Patch 1/7 - 4/7 are error message related patches. Patch 5/7 - 7/7 are testing related patches. v1 -> v2: - Use enum for error code. - Eliminate for-loop, directly get error message from array using array index. - Classify error reason of program loading failure. - Improve message when version mismatching.
