Hi, I'd like to get a kernel running on a z6. I've tried modifying the line for the "E2/A1200/E6/A910" for the correct usb device (it already has the right ep_in/ep_out) and tried booting a kernel I'd made and one I pulled from a .sbf file. In both cases it downloads it but I get a black screen for ~20 seconds then the builtin kernel/OS boots. Substituting something random for the kernel has the same affect. I'd also played around with boot_usb using lbl or a modified one that has an alternate kernel address but I'm not really sure the usb boot method would provide it the right data anyway so I haven't tried to modify boot_usb enough to do that the right way.
I see reference to signed validation of booting with the A1200, but then I also see that people appear to be using it. I also have no idea how one determines the legal value for kernel_addr, etc. (Is this loading this in an arbitrary place within the valid address space, or some expected location?) Can someone summarize the known issues that I need to deal with and how they were dealt with or differed in the ezx models? Thanks, -Will
