I'm just getting started; using this sample app in the Codewarrior Palm tutorial. Am able to debug it using POS, but don't understand what's happening when I debug on device. I'm building with debug target, and I think the prc is being downloaded - the device shows white screen with blinking box, and the CodeWarrior Palm OS Debugger Log Window shows "Connected to: USB Process created: Address=0x176F5A Size=0x6EE CardID=0 DbID=0xFFFE87" but, the prc window (titled "MyErrandD.prc (Thread 0x0)") shows nothing in the Stack pane, "no local variables" in the var pane, and nothing in the source pane. The red X in the toolbar is enabled (kill thread), and the debug button is enabled as well (tooltip = "resume"). I can click Resume, but nothing changes either on the Device or in the Codewarrior windows.
Which device are you using? There is a device-side bug that affects many OS 4 devices where you can download an application using the debugger, but when the app stops at a breakpoint, no notification is sent back to the PC, making debugging impossible. I've seen this with the i705, the m130, and m515, and several Sony and Acer devices. If you have those devices, you need to get a serial cable or serial cradle for them to debug to them, since USB just isn't going to work.
