I've recently finished a project that I want to be able to deploy to a handful of devices, and have built the hex file in release mode in Crossworks with Level 1 optimisations. I can run it properly from within Crossworks over JTAG (the USB device enumerates, and FreeRTOS starts executing tasks as expected), but when I try to deploy the HEX files via Flash Magic and then reset the device (after verifying the uploaded hex file), nothing seems to happen. When I deploy it via JTAG in Crossworks and then reset the device, it also doesn't seem to execute (I have to run via F5).

Do I need to set some specific compiler option so that the code starts executing when building for release mode? I definately was expecting it to run (or remain in flash), and I'm not really sure what I'm doing wrong???

You need STARTUP_FROM_RESET. See the CrossWorks FAQs.

Have you defined STARTUP_FROM_RESET? See the CrossWorks FAQ.

Richard:

Thanks for that ... I added it to preprocessor definitions for 'release' mode and it works fine now. Here's the link if anyone else comes across this:
