On the E7T with a ROM Redboot I observe the following: - loading the app to RAM via GDB and starting it (continue) works fine. Application has not crashed in months. - loading the same code to RAM via Redboot (load -m xmodem) and starting it (go) will start the application but the systems hangs after a few seconds. Anyone a clue as to why this could be happening? Thanks, AS >From: Gary Thomas >To: Ali Sina >CC: eCos Discussion >Subject: Re: [ECOS] E7T ROMRAM startup anyone?
