Missing __thumb_startup()

[randylee]

so I've got this thing to go towards linking (all the direct compile problems somewhat taken care of) and it's saying it's missing __thumb_startup from the vector table.

Where should I be finding that and why isn't it there?

[randylee]

OK, so I figure this is something screwy with Beta version.  V1.1 comes out (production version) and I've done the same thing: Created the project and then export from CW10.5 and import to here (all the PE stuff) and then import the files into it.

Still missing this __thumb_startup() which is because I do not have a start.c file that got generated anywhere.

How do I tell this thing to generate one then?  Can I just import it from another project and put it there?

Hi Randy,

i had the same problem. There must a checkbox "generate startup code" in CPU settings, which is disabled.

Yep, sure enough.  Under Build Options->Startup in the component inspector for the CPU.  I'd guess this to be something that doesn't map exactly between CW and KDS export/import.

Fixed it tho by checking the box involved.

Typically this thumb_startup is part of the startup code. Have you added a startup code to your project?

I suggest you look at the examples created by the new project wizard to have a starting point.

This particular project, I created with the new project wizard and then imported my exported PE from the 10.5 project and then added all my code to it.

Any other project I've created in CW 10.X already has that sort of stuff created as part of the project. So, KDS, I have to explicitly add that sort of deal?  Interesting.
