    Aria,

    you need to direct the debugger to the location where you have installed the Sys/Bios files. The sources are there and then you can debug the issue. Above is not the debug output but a message by the tool that it can't find sources. This is usually the case if libs are built on another machine and contain the absolute paths.

    Otherwise there is a dedicated Starterware forum.

    regards,

    Aria,

    no, as we can't guess what code you have here: E_dataAbort: pc = 0x8000e6e4

    You really need to single step through this and figure out what is happening. Hint: usually it is some kind of peripheral that has not been enabled (clocked). So ARM can't access the registers and will throw an exception.

    Regards,

    I don't think this is a public release. At least I can't find it on our web pages. So you should ask the person who gave this to you for support. We can't discuss early engagements on the public forum.
