Hi Daniel, I managed to set up DDD today and do some debugging. What I did:
- configure the kernel for zImage - CONNFIG_ZBOOT_ROM, so that my zImage can run from flash - then I loaded this zImage to the Flash and using my JTAG adaptor I can connect with the DDD debugger and step through the code, even with C symbols when I use the file arch/arm/boot/compressed/vmlinux. With the help of this, I could see that the Code works until it reaches inflate.c, Line 579. There it comes to an endless loop, and I don't know why :-( Do you have some idea?
