What could cause this? Should I assume the program was loaded successfully as it says?

Hello Westin,

Do you use the built-in xds100v2 or an external standalone JTAG emulator?

It seems to me that the program has been loaded correctly.

I use an standalone xds100v2. It does look like it loaded correctly. I just didn't know if there was anything else it had to do after flashing which it failed to do.

I have more information that may help. The issue doesn't happen if the "Run Target After Program Load" checkbox in the settings window is unchecked. Can anyone tell me what unchecking this actually does? If it is unchecked, does it prevent the module from running the program until it has been rebooted?

Additionally, this checkbox state doesn't seem to persist when the UniFlash is reopened. Is that behavior expected?

It seems to me that the problem is caused by your code which has been programmed into the flash.
