DS-5 bare metal wait error after run "debug"

CKO

I tried to run the bare metal script ("Hello World ANSI C Project - ARM Compiler 5 DS-5 built-in") on DS-5 debug software. However, it hangs on somewhere on "wait" commands as below which is not yet reached the breakpoint on main function. Notes, it could not even proceed to the "Step Over Instruction (F6)".

Commands:

Stopping running target Altera - Arria 10 SoC on connection
Connected to running target Altera - Arria 10 SoC
Execution stopped in SVC mode at S:0x8001E748

Looking for helps :(

    I don't have a board to test this code with - from it looks like the code is loading correctly to 0x80000000. I recommend setting to "debug from entry point", and see if you can single step the first instruction.

    I see from your connection, that the target is in an abort mode when you connect to it... it may be that the board needs to be running an independent boot loader to initialize memory etc. These are usually pre-installed on boards, but you may wish to contact the board vendor for specifics.
