Seeing Cortex Flash timeout

Mark Kraft

Starting up a Luminary Micro design with Keil.

Getting a Flash timeout message when attampting to download to flash.

Telling me to reset target and try again.

Anyone have an idea what message may indicate?

    I have resolved this issue by removing then adding back in the flash algorithms for the LM3S3748.

    I verified this using the 3748 eval board. My project was based on the USB-mouse example. I erased the flash and attempted to download. I received the same error message as I did with my own hardware.

    "Flash timeout".

    To resolve this I removed the flash algorithms present in the original project for 128k and 32k flash. I placed the 128k back into the list and was able to program.

    Oddly, before erasing the flash on the eval board. The flash settings as they were originally set in the project worked!
