I've been building a small app on a TWR-K60N512 (includes the serial card) for several days using a Segger JLink programmer connected to the 20-pin debug header. This has been working just fine. Now I tried removing the programmer to allow the board to run standalone and it doesn't boot. I'm not using the JLINK for power (J13/USB does that); so I'm confused.
With JLINK attached, I can power cycle the board and then just run a JLINK script (see below) to restart it and that works fine; so that tells me that the boot flash is properly programmed (doesn't it?).
I noticed that with the JLINK attached, the "RESET" button on the TWR-K60N512 also just locks up the board (I assume it goes to the same "space" as a powerup). Any ideas what I might be doing wrong?
